Liability Ultrasonic testing is a function of using the proper equipment (electronics, transducer, cable and couplant combination) for the inspection and a qualified operator who knows how to use this manual, the instruments and all calibration procedures. The improper use of this equipment, along with the improper calibration can cause serious damage to components, factories, facilities, personal injury and even death. ALL DANATRONICS ULTRASONIC FLAW DETECTORS AND THICKNESS GAGES ARE NOT INTRINSICALLY SAFE AND SHOULD NOT BE USED IN ANY HAZEDOUS OR EXPLOSIVE AREAS.

It is understood that the operator of this equipment is a well trained inspector qualified by either their own company or another outside agency to issue Ultrasonic Level I, 40 hour class room training in Ultrasonic Theory. Danatronics, Corp. and any of its employees or representatives shall not be held responsible for improper use of this equipment for its intended use. Proper training, a complete understanding of Ultrasonic wave propagation, thorough reading of this manual, proper transducer selection, correct zeroing of the transducer, correct sound velocity, proper test blocks, proper cable length, proper couplant selection all play a factor in successful ultrasonic flaw detection and thickness gaging. Special care should be taken when test pieces have rough or painted surfaces, particularly those applications where the test piece is thin to begin with as doubling of the echoes is possible even if the transducer is capable of measuring the desired thickness. As transducers wear or heat up, results can be either too thin due to a lack of sensitivity as a result of wear or too thick due to heating up of the transducer, referred to as “drift.”

in each mode. You can use the , to manually toggle the various screen sizes. Generally you find the parameter you would like to adjust and press on the display to adjust or choose from a menu. As an example, if you would like to change range, press range and either enter the value then press SET or scroll using the up or down arrow to the desired range. The same is true of gain. For other common functions such as Energy, click on Energy and choose 50, 100, 150, 300 or 600 Volts.

iFlaw is set up with multiple screen sizes and orientation in both portrait (up and down) and landscape modes. (Insert pixel counts in each of the six screen sizes). iFlaw can even be set up for the unit to automatically rotate the screen via a built-in gyroscope. This is under the setup menu. For maximum vertical pixel data, we recommend portrait full screen as opposed to maximum horizontal data is realized in landscape mode. See all six screen formats below, they can easily toggle by pressing

Display Screen

Please orient yourself with the display screen. You can either have the display in landscape mode as seen above or portrait mode simply by rotating the unit 90 degrees with the connectors on the side as opposed to the top. The display comes with a protective plastic screen sold separately in packages. Simply lock the display using the Lock icon then use water and a clean cloth to clean off any fingerprints or excess couplant.

Left Hand vs. Right hand icon set up. You can also set iFlaw up to have the icons conveniently on the left hand side of the screen or on the right hand side. With the left hand tab you can even turn on slew on feature where up and down keys are convenient when changing common parameters such as gain. The default settings are for landscape mode, left hand icons. To change to right hand mode, press setup, display, orientation, press right hand radio tab.

CALIBRATION

Straight Beam using auto calibration (horizontal range using a 1” test block)

1. set range to desired material range either 5 or 10 inches…5 inches is used in this example.

2. set gain up or down so you have 5 usable echoes on the screen of at least 20% amplitude on the 5th echo

3. make sure all values are set correctly such as full wave, correct frequency and filter positions…

4. in the large value box in the top right, click it and set to Gate 1 Thickness

5. Using the keys, choose if you want to measure the peak of gate one or the edge

6. move gate one by clicking and dragging to the first detected echo

7. press the CAL key

8. press Cal Zero

9. enter known thickness of 1.000 (or just 1 also will work), press the cal key

10. slide gate one to 5th echo making sure echo breaks the gate so you get a detected echo in the top right

11. press CAL VEL, enter 5.000 (or just 5)

12. Press CAL DONE

13. Now move the gate over each echo to verify the readings are correct. For a contact transducer, you can also verify the numbers by checking the zero value of less than 0.075 in and the sound velocity of steel (typically between .2220-.2390 in/usec).

Danatronics, Corp.

20

Angle Beam Calibration using auto cal and IIW block type 2 in inches mode (2” and 4” reflectors)

1. Set range to 5”

2. Set angle of wedge (typically 30,45,60 or 70 degree)

3. Set shear wave sound speed to .1270in/usec

4. Enter the test block thickness to account for the depth component of the trig functions

5. verify probe angle peaking echoes back and forth on wedge (Hint: it is very useful to turn on the Peak feature to verify peak echoes)

6. Peak 2” and 4” echoes moving probe back and forth (Hint: it is very useful to turn on the Peak feature)

7. Stop and hold probe once echoes are peaked (Hint: it is very useful to press the Freeze F key as you can easily now perform a cal on the frozen echoes)

8. In the large measure box in the top right, set gate one to soundpath

9. in the other 4 measure boxes set one of them to gate one surface distance

10. in anther of the 4 measure boxes set another to gate one depth

11. Move gate one to 2” echo

12. press Cal

13. Enter 2.000 or 2 then press Cal

14. Slide gate to 4” echo

15. Press CAL VEL

16. Enter 4.000 or 4”

17. Press Cal done

21

Checking Vertical Linearity:

Couple to the 1” thick IIW type II, make sure constant uniform pressure is applied such as using a weight to hold down the transducer. Now adjust the gain so the echo amplitude is 80%, lower your gate level to 2%, use reference db and adjust to 6 db, take out 6 db and check the vertical linearity is now 40%, continue the process, take out 6 db, amplitude should be 20%, 10%, 5%. The vertical linearity of the iFlaw is 1% of full screen height.

Display contrast, colors and backlight

The iFlaw has an automatic light sensor to choose the best light and contrast or it can be manually set by pressing the Setup key, display, brightness and use scroll bar to see the contrast dynamically change. The backlight can also be set to “auto” or sensing modes. Auto uses the light sensor to change the display contrast to white on black and filled in mode for the optimal sunlight readability.

You can also change the colors of the waveform, grid, text and other choices but Danatronics has chosen the optimal colors for maximum use of display contrast and battery life. Returning to the factory settings upon reset will re-install these colors if they are changed on purpose or inadvertently.

Note: Leaving the brightness to maximum setting will reduce battery life.

Making thickness readings:

modes of thickness readings as follows:

1. Edge depth

2. Peak depth

3. 1st Peak in Gate

4. Floating gate, -6db or -12db

5. echo to echo (to ignore coatings)

there are also icons in the top left or right (depending on left hand or right hand setup, default is left hand) in landscape mode that allow you to choose between first echo in the gate 1 or 2, edge or peak as seen by these icons

iFlaw

29

1. Edge depth is used when you want to measure the leading edge of the signal breaking gate 1.

2. Peak depth is used when you want to measure the thickness to the peak or highest signal in gage 1.

3. 1st Peak in gate is used when multiple echoes break the gate but you do not want to measure the highest but the first breaking gate 1.

1. Floating gate is an option and is the most accurate for making thickness readings as the echo amplitude variation does not effect the thickness reading as it can be set to either ½ way down -6 db from the peak or 25% of the peak at -12db. When using the B-scan option or looking for the most accurate thickness readings, the floating gate is the best to use.

2. Echo To Echo is standard is used to ignore painting or coatings as they have a given thickness and a different sound velocity of Steel. To use echo to echo, turn on echo to echo mode, using one of the 5 measurement boxes at the top and make sure the first echo breaks gate 1 and the second echo breaks gate 2. For the highest accuracy, make sure both gates are set the same at either edge or peak modes.

There are 5 measurement boxes at the top of the screen, in this example, the icons above from left to right are gage 1 down arrow is depth, gate 2 down arrow depth, 2%C is gate 2 % of Dac curve and 1% MX is gate one Max amplitude while the large font box is set to Gate 2 Angular distance.

5 Using the DAC and TVG

DAC and TVG

Distance Amplitude Correction (DAC) and TVG are standard features of iFlaw. DAC is used to draw a curve or multiple curves indicating the peak amplitude of decaying echoes due to normal material attenuation (absorption of sound) and beam spreading as it passes through materials. As a general rule on the same material once a DAC curve is set up, Echoes below the curve can be considered smaller in size than that used on the DAC block (a specific hole size at various depths) while echoes exceeding the curve can be considered larger than that used from the reference block. The main reason for the DAC curve is to visually compensate for the effects of sound field, near field, attenuation and beam spreading as well as surface roughness.

1. Press the SETUP key, options and choose which type of DAC you would like from following choices:

ASME (Single Curve), ASME-3 (3 Curves of Main Peaks and -6dB and -14dB as warning curves) or JIS (Japanese Industrial Standard)

2. If you would like Ref/Correct on touch it and turn it on. If Reference Correct is chosen, the operator can easily add scanning gain proportional to the DAC reference curve. In other words, the curve will adjust up or down relative to gain increases or decreases if Ref/Correct is turned on

3. exit the SETUP menu by pressing Close

4. Use the key to enable the DAC set up the left or right side of the display (factory default setting is the left side)

5. While is activated, there are new buttons for Capture, ADD, Delete, Erase and Done to assist in the set up of the DAC Curve

6. while DAC is on iFlaw will keep the gates as active keys as the Auto 80, Gate Start, Widths and Levels will be important while grabbing the desired echoes

7. Set the Desired parameters for the chosen material and transducer such as contact, frequency, filters, range…so that all the DAC holes will be visible on screen. The below sequence applies to either contact or angle beam but contact is used here.

8. Peak up the first (Closest flaw to the surface), 9. Gate the detected echo 10. press the G1 Auto80 key (this allows for maximum display resolution even though after selecting the

second echo, the first echo will be off scale…larger than 110% amplitude) 11. Press Capture Key to store the first echoes peak, an X will be drawn on the peak 12. move the gate to the second echo, press auto 80 and iFlaw will automatically start to draw the curve

between the first X and the second echoes peak

iFlaw

31

13. Repeat this process until all points are needed and press Done 14. if any echoes need to be re-done, press either Delete entire curve or Erase a single point. 15. When using Auto 80, you will need to lower the gain to get the curve to remain on screen. 16. your DAC curve is now ready to use 17. the second gate normal operation returns to the normal operational mode 18. Once the curve is on, the operator can choose, in any of the 5 top measurement boxes db to curve or

amplitude to curve 19. while DAC is on, the operator has full command of gain, range, delay… 20. it is possible to select G1 Alarm in DAC mode to alarm on the primary curve, -6 or -14db curve by

pressing the G1 alarm key 21. it is not recommended to use echoes below 20% amplitude for flaw sizing while DAC is on. 22. it is possible to create a Time Corrected Gain (TVG) curve from a DAC curve by pressing the TVG

View /DAC view button

23. To Turn off DAC, press , the DAC off 24.

TVG is used to adjust the amplifier to create all echoes the same height independent of material wall loss or attenuation, you can adjust gain, range, delay…while TVG is on

Turn on the TVG feature from the setup, options keys

1. press the DAC/TVG button on the left hand side of the screen 2. touch the TVG radio tab to on 3. the bottom of the screen will show new keys for TVG as ADD, DELETE, ERASE and Done 4. to EXIT TVG press the DAC/TVG key 5. Gate the first echo 6. Press ADD 7. continue to gate the selected echoes and press add 8. when finished press DONE 9. Now all echoes will be at the same height from the start of TVG to the final echo added

Setting the gain,

Press the key and you can either use the up and down arrows to slew the gain and it will increase in speed as you hold the key down longer, enter a value such as 45 dB or use the “gain slew on” to place an up and down arrow on the left hand side of the display to dynamically turn the gain (echo height) up or down, simply by using your left thumb if it is in the wrist strap. Also in gain you can turn “Ref On” which will be the reference level. Once this key is pressed, you can add scanning gain + or – added to the main gain and then either add the two values together or re-set the scan gain to + or – 0.0 db

Delay:

Delay is used to shift or delay the left side of the screen. As an example you can have a 5 inch range and one inch of delay would ignore the first one inch not visible on the screen and your range would remain un-changed at 5 inches.

Velocity:

Every material has its own unique sound speed. You can enter the value directly or use the chart as a close approximate. iFlaw will calculate the exact sound speed when performing a calibration on a known thickness, see calibration section

Zero:

This is used in calibration for eliminated an offset created by cable length, couplant, wear surface, delay lines, water paths and wedges. See calibration

Angle:

This is used to enter the angle of a wedge to calculate angular distance, surface distance and depth to a defect.

Danatronics, Corp.

38

Thickness:

This is used to account for which leg depth component is being calculated in angle beam or for the when using the B-scan option to calculate what is displayed as a percent of the screen range.

Filter

This is used to match the general frequency of the probe being used and to filter out frequencies not wanted, choices are:

.2-10 Mhz

.2-1.2 Mhz

.5-4 Mhz

1.5-8.5 Mhz

5-15 Mhz

8-26 Mhz

2-21.5 Mhz

Rectification

Displays RF (Radio Frequency), Full Wave, half wave +, Have wave –

iFlaw

39

Range:

Selectable from 0-400” or metric equivalent or can scroll

Gates

Used as the measurement area of concern. As an example of a typical flaw detection application, gage one can be set to detect for an echo breaking the gate in a positive alarm condition and set to display amplitude while gage 2 is typically set in a negative fashion to detect the loss of a back wall echo dropping out of the gate due to a flaw appearing in gate one, attenuation or even a non-parallel crack not returning the back wall echo.

PRF

Used to set pulse repetition frequency between 30-1000 Hz. When using long sound paths it is recommended to set this value to 30 hz. So that “wrap around” or the appearance of the 2nd main bang does not show on the display.

Frequency:

The bandwidth of iFlaw is .5-30 Mhz at -3 dB. As such you can enter any frequency between these values with the text editing box to match the frequency of the probe being used.

Energy

Used to optimize the signal for the best image in signal to noise. For example, a highly attenuating cast steel would likely require the maximum vs. when looking for the best near surface resolution

you may select a low value. Choices are 50V-600V. NOTE: Danatronics does NOT ASSUME Transducer failure if the voltage above 400V is selected for transducer with inductors. This can cause serious damage and probe failure. To activate the 600 V, go to Setup, initial Settings, Energy and press the 600V tab and read the warning note.

Damping

Like energy, Damping is used to improve the image presentation. There are no set hard fast rules but rather try it to clean up the signals in terms of what you are looking to see. As an example, a flat

Danatronics, Corp.

40

bottom hole very close to the back wall, you should try to adjust the damping, energy, filters, frequency and rectification to try to get a clear separation of the two signals.

Mode

Choose between, Pulse Echo, Dual or Through transmission modes. Pulse echo is sound entering and returning to a single transducer on one side of the test block, Dual is using a dual transducer (2 elements in one housing also referred to as pitch/catch) which uses the transducer on one side of the test piece and still calculated the correct thickness. Dual transducers are typically used in corroded thickness applications. Thru mode is when using two transducer on the opposite side of a test piece where the displayed sound path will only represent one sound travel as opposed to pulse echo or dual where the thickness is calculated by T=Vt/2 where T = thickness, V = Velocity, t = measured time and we divide by 2 representing sound going into the part and back to the source. Thru is used typically attenuating materials such as rubber, fiberglass and castings where you can not get sound in and out of the part from one side. It is also used in Velocity calculations.

Reject (Linear Reject)

Used to get rid of low level signals (noise). The use of reject is typically not allowed when adhering to codes. The use or reject on iFlaw is totally linear and does not affect echo amplitude. Reject can be set to off, 1-80% FSH (Full Screen Height)

Reject can be used to get rid off unwanted baseline noise…be careful as a lot of codes do not allow the use of reject. The reject level is here in green at 20% and also indicated by a red arrow on the left side of the screen.

6 Special iFlaw Functions

Using the Save Option/lefty vs. righty mode

For the datalogger version only, you are able to save your data via the Save option. Please note, the save key can appear either on the left side or right side in landscape mode or top right or top left in portrait mode. To move the set of icons, go to Setups, display, orientation then choose lefty or righty.

To use the Save option, follow this step:

1. From the Measurement mode screen, press [F1] (Save). Please note, if the user has been set to righty under the Display Screen, the Save will appear over the F3 key.

Note: Save is on the left (default) or right in this image as seen by this icon: . also note to save a

screen capture press and hold the key.

iFlaw

47

Note: Save is on the left in the above screen shot.

Using the Freeze Option

For the datalogger version you can freeze your data via the Freeze option. This feature is great for high temperature readings or trying to hold a signal on the screen. Once the F for Freeze button has been pressed on the right side of the screen, you can move the gates over the desired echoes for some post processing and then press the Save key to send the data to the datalogger. Freeze will highlight and toggle on or offer

simply by multiple presses. Helpful Hint: iFlaw can even accept a calibration in straight beam or angle beam from a frozen screen. This is particularly useful when doing and angle beam calibration as it is sometimes difficult to hold the peaked echoes on the test block while making adjustments.

Danatronics, Corp.

48

Peak Memory:

Peak can be set to peak, Peak hold or off. Peak retains the peak signal while scanning back and forth. Peak hold holds onto the peak envelope while showing the live waveform underneath. The last choice is off. Peak and Peak hold are ideal for peaking a signal or for holding the peak envelope which is ideal for flaw sizing using the -6db drop method. As an example if you are on peak hold and say the peak of the signal is at 80%, you can lower the gate1 level to 40%, press or drag the gate start to the edge of the envelope at 40% (-6db) then click or drag the gate1 width to the trailing edge of the envelope also at 40% and the total gate width measured units will represent the defect size.

iFlaw

49

Zoom

Zoom is preformed by setting gate 1 start and width over the desired zoom area and double clicking the gate level bar. Please note in zoom mode, delay and range tabs are grayed out and can not be change d until double pressing to un-zoom by double clicking again.

Lock simply locks the entire display ideal for scan ning and screen cleaning. To unlock, slide the unlock slide bar on the displa y when the prompt appears.

Using the DAC and TVG Features:

DAC and TVG

Distance Amplitude Correction (DAC) and TVG are standard features of iFlaw. DAC is used to draw a curve or multiple curves indicating the peak amplitude of decaying echoes due to normal material attenuation (absorption of sound) and beam spreading as it passes through materials. As a general rule on the same material once a DAC curve is set up, Echoes below the curve can be considered smaller in size than that used on the DAC block (a specific hole size at various depths) while echoes exceeding the curve can be considered larger than that used from the reference block. The main reason for the DAC curve is to visually compensate for the effects of sound field, near field, attenuation and beam spreading as well as surface roughness.

25. Press the SETUP key, options and choose which type of DAC you would like from following choices:

ASME (Single Curve), ASME-3 (3 Curves of Main Peaks and -6dB and -14dB as warning curves) or JIS (Japanese Industrial Standard)

Danatronics, Corp.

26. If you would like Ref/Correct on touch it and turn it on. If Reference Correct is chosen, the operator can easily add scanning gain proportional to the DAC reference curve. In other words, the curve will adjust up or down relative to gain increases or decreases if Ref/Correct is turned on

27. exit the SETUP menu by pressing Close

28. Use the key to enable the DAC set up the left or right side of the display (factory default setting is the left side)

29. While is activated, there are new buttons for Capture, ADD, Delete, Erase and Done to assist in the set up of the DAC Curve

30. while DAC is on iFlaw will keep the gates as active keys as the Auto 80, Gate Start, Widths and Levels will be important while grabbing the desired echoes

31. Set the Desired parameters for the chosen material and transducer such as contact, frequency, filters, range…so that all the DAC holes will be visible on screen. The below sequence applies to either contact or angle beam but contact is used here.

32. Peak up the first (Closest flaw to the surface), 33. Gate the detected echo 34. press the G1 Auto80 key (this allows for maximum display resolution even though after selecting the

second echo, the first echo will be off scale…larger than 110% amplitude) 35. Press Capture Key to store the first echoes peak, an X will be drawn on the peak 36. move the gate to the second echo, press auto 80 and iFlaw will automatically start to draw the curve

between the first X and the second echoes peak 37. Repeat this process until all points are needed and press Done 38. if any echoes need to be re-done, press either Delete entire curve or Erase a single point. 39. When using Auto 80, you will need to lower the gain to get the curve to remain on screen. 40. your DAC curve is now ready to use 41. the second gate normal operation returns to the normal operational mode 42. Once the curve is on, the operator can choose, in any of the 5 top measurement boxes db to curve or

amplitude to curve 43. while DAC is on, the operator has full command of gain, range, delay… 44. it is possible to select G1 Alarm in DAC mode to alarm on the primary curve, -6 or -14db curve by

pressing the G1 alarm key 45. it is not recommended to use echoes below 20% amplitude for flaw sizing while DAC is on. 46. it is possible to create a Time Corrected Gain (TVG) curve from a DAC curve by pressing the TVG

View /DAC view button

47. To Turn off DAC, press , the DAC off 48.

51

TVG is used to adjust the amplifier to create all echoes the same height independent of material wall loss or attenuation, you can adjust gain, range, delay…while TVG is on

Turn on the TVG feature from the setup, options keys

10. press the DAC/TVG button on the left hand side of the screen 11. touch the TVG radio tab to on 12. the bottom of the screen will show new keys for TVG as ADD, DELETE, ERASE and Done 13. to EXIT TVG press the DAC/TVG key 14. Gate the first echo 15. Press ADD 16. continue to gate the selected echoes and press add 17. when finished press DONE 18. Now all echoes will be at the same height from the start of TVG to the final echo added

Linear parameters are as follows:

• Prefix – up to 12 characters, used as a prefix for the IDs. • Start – the starting ID up to 12 characters; the same # of characters as End. • End – the ending ID up to 12 characters; the same # of characters as Start. • Step – the incremental step, defaulted to 1 (1-100) • Pattern – Standard or Reverse. This specifies the ordering of the IDs.

The example in Figure 7 would produce a file with IDs AAAA001, AAAA002, etc., up to AAAA100. Start and End must be the same number of characters, and the total length of the ID string (Prefix + Start or End) must not exceed 20 characters.

Note the keyboard icons next to Prefix, Start, and End. Pressing a keyboard icon causes the soft keyboard to be displayed so that the parameter can be edited.

Soft Keyboard Each text item to be entered has an associated soft keyboard button, which will activate the soft keyboard so that user can enter the information. This is illustrated in Figure 16:

Figure 16

The keyboard should have either upper case letters, lower case letters, or numbers. The up-arrow (^) button will toggle back and forth between upper and lower case. In other words, all lower case letters will become upper case or vice versa. There should also be a button which toggle between letters and numbers. If letters are displayed, the button will be labeled 123, and will cause numbers to be displayed. If numbers are displayed, the button will be labeled ABC, and will cause letters to be displayed.

Open

If the user presses Open on the Files dialog (Figure 2), the application will close the previous open file, open the selected Datalogger file, and return to the main measurement screen.

Print

If the user presses Print on the Files dialog (Figure 2), the selected Datalogger file is printed (to be specified later).

Waveform Adjustments

The main waveform adjustments on an ultrasonic flaw detector are range delay, gain, calibration (zero offset and velocity), gates and what type of measurement is needed. These are performed simply by touching what needs to be adjusted and either ender the value, slew or choose from the pick list.

Calibration blocks. It is generally a good practice to have NIST traceable calibration blocks to set up your instrument for the proper calibration and subsequent test. Common blocks are IIW type 1 and II, DSC blocks, rompus blocks, Flat Bottom Hole blocks (FBH) and step blocks of known thicknesses such as .100-.500 in .100” steps or .100”, 250”. 500”, 759” and 1.000”. It is also very important to have test blocks that correspond with the material you are testing such as Carbon Steel or Stainless Steel.

Performing a time base or Horizontal Linearity Check

1. Set a 1” IIW block on its side

2. Adjust the range to 10”

3. place transducer on 1” test block

4. Adjust the gain so that you have 10 useable echoes where the last echo is at least 40% high

5. Shut off Gate 2

6. Adjust Gate 1 start at .5”

7. Adjust Gate 1 Width to 2 inches

8. Adjust Gate level to 20%

9.

10. in the large box in the top right of the display, set to gate 1 Thickness

11. Set and toggle the gate 1 depth bar in the top right to edge

12. if you have the floating gate option, you can turn it on in lieu of setting gate 1 level to 20%

13. perform a calibrate zero offset on the one inch section

14. perform a calibration of velocity on the 10 inch section…this can be done visually to see that the 10th echo is at the 10th division at the 20% line or by moving the gate start out to the tenth echo

15. Scroll through each echo to make sure the readings are at 1.000-10.00” respectively within .020”

To adjust any of the above settings, from the main measurement screen, simply use the left, right, up or down arrow until the desired parameter is highlighted. In other words the arrow keys will act as a mouse or cursor to highlight the desired parameter. As an example, use the right arrow unit Rectify is highlighted,

then press Menu/OK to adjust the rectification mode by again using the right or left key to except, press F1=exit. You can follow the same procedure for Gain, Blanking and Range.

Note: if you are measuring a 2 inch part with a 1” range, no echoes will be visible. Please adjust range accordingly. The Wave is defaulted to a 2 inch range as a factory setting.

Rectify-RF, Full Wave, Half+ and Half – Use the left or right arrow keys to highlight RECT. for rectify the up or down arrows to select between RF, Full Wave, Half Wave + or Half Wave -. The default setting is Full Wave Rectified.

iFlaw can easily be configured with popular and common software options wither initially or upgraded in the field. The options can be found under the setup key, options. If the function is “grayed out” that means it is not installed in your unit. All units leave our factory (or as they become available) with the following

options pre-programmed into iFlaw but not necessarily turned on:

16. Floating Gate 17. B-Scan

18. Back Echo Attenuator 19. Extended range

20. DGS 21. Pipe Curvature correction

22. AWS code software

Software options: AWS angle beam flaw sizing code, JIS, TVG, AVG (Europe), Back echo attenuation, spot-weld, auto phase reversal, echo to echo thickness mode, B-Scan (time based and encoded), curved surface angle beam correction, spot weld software. Software release TBD after product introduction.

Please note, some software options may not be available at the time of initial iFlaw product release

Battery use and care:

The iFlaw uses state of the art Li Ion batteries. You can use one battery to make the iFlaw lighter and receive approximately 4 hours of continuous use or 2 batteries for approximately 8 hours of continuous use.

Backlight, brightness, contrast, pulser voltage and measurement rate (PRF) will affect battery life. Li Ion batteries do not have memory issues and plugging in the battery charge at any time will not affect the

batteries performance. There is a constant battery symbol in bottom right of the display, the below example shows they are charging

.

Either there is a charging symbol or a green, yellow 5-10% remaining life or red and flashing with 5 % life remaining for each of the batteries. At this point you should either plug in the included AC charger adapter or use the external Charger adapter sold separately. To remove one or both batteries, open the battery door on the bottom of the iFlaw, hold the iFlaw up to slide out the batteries. Insert the new battery with the top

side (terminal) up.

Danatronics Re-cycles, we ask you do the same by disposing of all batteries properly to protect our environment.

DO NOT OPERATE OR STORE THE IFLAW OUTSIDE THE RECOM MENDED TEMPERATURE RANGE AS SEEN ON THE SPECIFICATIONS PAG E.

Do not carry iFlaw by the back bail piece, this can let go an cause serious damage to the iFlaw and surrounding property.
