30 CALIBRATION PROCEDURES

31 GENERAL

The purpose of the calibration is to attenuate the amplified voltage signal from each transducer Adjusting the resistance of a potentiometer will yield a voltage in the range of 5 VDC representing the value of the desired engineering units

The front panel of the meter is equipped with six (6) potentiometers fitted with turns counters and lever locks Each is located under the display ofthe fculction served

Please note that the analog output of the meter assembly is raw output from each of the components the analog output signal is not the same as the value displayed by the meter Calibration charts are provided at the end of the manual to display the difference in the meter and analog output

The decimal point for each display is adjusted by moving the position of a jumper (JP I through JP5) The jumpers are located at the front end of the printed circuit board near the ribbon cable connector that leads to the conespondlng output Moving to the left positions the decimal point closer to the left side ofthe display

NOTE The amount of resolution available from the meter display is a function of the units that the various outputs are calibrated in For example LIFT can be displayed in units of Ibsf Newtons or kilograms with 1936 Ibs being equivalent to 88 kg or 8632 Newtons The readouts used are 4 of dIgits They will display a value up to 9999 In

~ this case a calibration in kilograms will provide 3 digits of resolution XXXX However ifNetons are chosen then only two digits of resolution will be available (XXXX) Therefore the units that yield a suitable resolution for the measurements performed must be chosen

32 TWO COMPONENT DYNAM01VlETER

321 GEgtIERAL

The assembly has been calibrated (in grams) prior to shipping (calibration data provided at end of this manual) The purpose of the calibration is to attenuate the amplified voltage from each transducer Adjusting the resistance of a potentiomeler will yield a voltage in the range of plusmnIO VDC representing the value ofthe desired engineering units

Each signal conditioning board features a potentiometer for GAIN adjustment (RI3) (please refer to pg 6 of the L VMshy110 Instructions) This potentiometer is mounted onto the enclosure front cabinet 2) The Gain potentiometers will be used in conjunction with the brass thumbwheels ofthe dynamometer for calibration

A fixture or bench surface allowing the dynamometer to be mounted in two orientations and a weight set are required for calibration (refer to Fig 4)

322 Ln COMPONENT

Remove the dynamometer j1om the tesr section Secure it to the calibration fixture or clamp the unit LO a bench so that the strut and shroud exleod beyond the edge of the bench as shown in figure 4

2 Monitor the output from the L1FT readout Adjust the LIFT LjDT core thttmbwheel until the voltmeter display reads 00(0

6

3 Load the LIFT beams with known weights equal to the maximum desired operating range (maximum rating of 15 Ibs) Adjust the LIFT Gain potentiometer so that the digital display yields the magnitude of the des ired units (ie Ibsf or Newtons)

4 Remove weights Verity zero If necessary adjust the LIFT thumbwheel so that the display reads 0000

5 Reload the weights used in step 3 If necessary adjust the SPAN potentiometer Repeat steps 3 through 5 until ZERO is verified

6 Detenmine the slope and intercept of the calibration curve by applying decreasing loads of known weights Record and graphically plot the results of known weight versus digital display

323 DRAG COMPONENT

1 Remount the dynamometer on the calibration fixture or bench so that the drag beams may be gravity loaded (ie so that the strut is horizontal) as shown in figure 4

2 Monitor the output from the DRAG readout Adjust the DRAG LVDT core thumbwheel until the display reads 0000

3 Load the dynamometer with known weights equal to the maximum desired operating range (maximum rating of 8 Ibs) Adjust the DRAG Gain potentiometer following the same procedure described above in steps 3 through 6 for the Lift Component

33 PRESSURE TRANSDUCER

331 GENERAL

30 CALIBRATION PROCEDURES

31 GENERAL

The purpose of the calibration is to attenuate the amplified voltage signal from each transducer Adjusting the resistance of a potentiometer will yield a voltage in the range of 5 VDC representing the value of the desired engineering units

The front panel of the meter is equipped with six (6) potentiometers fitted with turns counters and lever locks Each is located under the display ofthe fculction served

Please note that the analog output of the meter assembly is raw output from each of the components the analog output signal is not the same as the value displayed by the meter Calibration charts are provided at the end of the manual to display the difference in the meter and analog output

The decimal point for each display is adjusted by moving the position of a jumper (JP I through JP5) The jumpers are located at the front end of the printed circuit board near the ribbon cable connector that leads to the conespondlng output Moving to the left positions the decimal point closer to the left side ofthe display

NOTE The amount of resolution available from the meter display is a function of the units that the various outputs are calibrated in For example LIFT can be displayed in units of Ibsf Newtons or kilograms with 1936 Ibs being equivalent to 88 kg or 8632 Newtons The readouts used are 4 of dIgits They will display a value up to 9999 In

~ this case a calibration in kilograms will provide 3 digits of resolution XXXX However ifNetons are chosen then only two digits of resolution will be available (XXXX) Therefore the units that yield a suitable resolution for the measurements performed must be chosen

30 CALIBRATION PROCEDURES

31 GENERAL

The purpose of the calibration is to attenuate the amplified voltage signal from each transducer Adjusting the resistance of a potentiometer will yield a voltage in the range of 5 VDC representing the value of the desired engineering units

The front panel of the meter is equipped with six (6) potentiometers fitted with turns counters and lever locks Each is located under the display ofthe fculction served

Please note that the analog output of the meter assembly is raw output from each of the components the analog output signal is not the same as the value displayed by the meter Calibration charts are provided at the end of the manual to display the difference in the meter and analog output

The decimal point for each display is adjusted by moving the position of a jumper (JP I through JP5) The jumpers are located at the front end of the printed circuit board near the ribbon cable connector that leads to the conespondlng output Moving to the left positions the decimal point closer to the left side ofthe display

NOTE The amount of resolution available from the meter display is a function of the units that the various outputs are calibrated in For example LIFT can be displayed in units of Ibsf Newtons or kilograms with 1936 Ibs being equivalent to 88 kg or 8632 Newtons The readouts used are 4 of dIgits They will display a value up to 9999 In

~ this case a calibration in kilograms will provide 3 digits of resolution XXXX However ifNetons are chosen then only two digits of resolution will be available (XXXX) Therefore the units that yield a suitable resolution for the measurements performed must be chosen

3 Load the LIFT beams with known weights equal to the maximum desired operating range (maximum rating of 15 Ibs) Adjust the LIFT Gain potentiometer so that the digital display yields the magnitude of the des ired units (ie Ibsf or Newtons)

4 Remove weights Verity zero If necessary adjust the LIFT thumbwheel so that the display reads 0000

5 Reload the weights used in step 3 If necessary adjust the SPAN potentiometer Repeat steps 3 through 5 until ZERO is verified

6 Detenmine the slope and intercept of the calibration curve by applying decreasing loads of known weights Record and graphically plot the results of known weight versus digital display

323 DRAG COMPONENT

1 Remount the dynamometer on the calibration fixture or bench so that the drag beams may be gravity loaded (ie so that the strut is horizontal) as shown in figure 4

2 Monitor the output from the DRAG readout Adjust the DRAG LVDT core thumbwheel until the display reads 0000

33 PRESSURE TRANSDUCER

331 GENERAL

This procedure zeros the output of the pressure tIansducer The output of the pressure transducer is calibrated by the factory MKS Baratrol1 suggests that the transducer be recalibrated on a yearly basis Contact the local MKS representative directly to arrange for recalibrations

An instrument that provides a known or adjustable pressure has to be used The procedure below uses an ELD airwater u-tube manometer

332 PROCEDURE

I The transducer should be allowed a wanm up period of approximately 15 minutes to stabilize the zero setting

NOTE The zero wi ll shift slightly when the cabinet leg is used A small zero offset is significant only at very low pressure readings

2 Monitor the output from the PRESSURE readout

3 Insure that the manometer columns are plumb using the adjusting screw and the spirit level mounted on the base Connect the barbed fitting marked TOTAL to the valved tee fitting on one leg of the calibration airwater manometer with clear tubing (as depicted in fig 5) Set PRESSURE SELECTOR to the 0 position Note that the other leg ofthe manometer and tube marked STATIC are open to the atmosphere

4 Adjust the digital display to 0000 using the ZERO potentiometer

5 Open the valve at the tee Using the rubber bulb apply a pressure equaling the maximum range of the transducer (standard 10 WG) to the manometer and the transducer Close the valve

7

6 Adjust the SPAN potentiometer to display the applied pressure in the desired engineering units (ie inches of water TOR kPa etc)

7 Open the valve to vent the system When the manometer fluid is level check the pressure reading and if necessary readjust the zero Close the valve and reapply pressure as in step 4 Refme the digital display as in step 5 if necessary Lock the potentiometer setting

8 Repeat steps 4-7 for several measurements

9 Discornlect the manometer and reattach the TOTAL and STATIC tubing to the test section
