Instructions

Before the calibration can be checked, theinstrument and its aspirator sampling bulbmust be in operating condition as describedin the instrument Instruction Manual.

1. Attach the flow control to the calibrationgas tank.

2. Connect the hose to the flow control andto the instrument inlet fitting.

3. Open the flow control valve.

4. Record the meter reading after itstabilizes.

NOTE: It is not necessary to operate theaspirator bulb to obtain thecalibration sample. Depending onwhich calibration gas is used, theinstrument reading should bewithin one of the followingranges:

"This instrument has an internal span control.Adjust the span control to obtain the correct

reading for the gas used; if this cannot be done,replace the detector filament.

If the instrument does not read within theacceptable range, replace the detectorfilament unit (the black filament, part no.11355 in Models 2, 2A, 2B, 2C, 3, 4, 6, 20and 21, 40, 40S and 53 OR part no. 75476in the Model 5) and repeat the calibration

5. Close the flow control valve.

6. Remove the hose from the flow controland the inlet fitting on the instrument.

7. Remove the flow control from thecalibration gas tank.

Instructions

Test the operation of the pump and sampleflow indicator by momentarily placing afinger over the sample inlet of theinstrument. The flow indicator should be atthe top of the window when the inlet isopen; the indicator should then fall fromview when the inlet is blocked. If not, seethe instrument Instruction Manual forrequired maintenance.


2. Connect the hose to the flow control.


4. Connect the hose fitting to the inlet of theinstrument; after about 15 seconds theLEL meter should be stable and indicatingbetween 47 and 55%. If the indication is

not in the correct range, remove the rightend of the indicator and adjust the SPANor "S" control to obtain 50%.

5. Verify the oxygen meter indication; itshould be between 13 and 17%. (This is aresponse check only. The oxygen sensorshould be calibrated to 20.8% oxygen infresh air before each use.)

6. Disconnect the hose fitting from theinstrument.


8. Remove the hose from the flow control.

Instructions

Before the calibration can be checked, theModel 70 must be in operating condition.The instrument must be allowed to stabilizefor at least 1 hour in the STAND-BY mode ifpreviously stored OFF. If a sampling lineand/or moisturizing bottle are to be usedwith the instrument, they must be connectedto the instrument while the calibration ischecked.



3. Connect the hose fitting to the instrumentinlet or to the instrument sampling line, ifone is to be used.

4. Open the regulator valve.

5. Set the MODE switch to the ON positionand the RANGE switch to the range beingchecked.

6. Allow the instrument to reach a stableindication. Adjust the SPAN control, ifnecessary, to obtain the correct indicationfor the calibration gas used.

7. Remove the hose from the regulator andinstrument.

8. Close the regulator valve.

9. Remove the regulator from the calibrationgas tank.

Before the calibration can be checked, theinstrument and its aspirator sampling bulbmust be in operating condition as describedin the Maintenance section of theinstrument Instruction Manual.

The Gascope RANGE switch must be in the0-5 position (Model 60) or the LELposition (Models 62, 62S and 62 Special).




4. Record meter reading after it stabilizes.

NOTE: It is not necessary to operate theaspirator bulb to obtain thecalibration sample. Depending onthe instrument type and thecalibration gas used, theinstrument reading should bewithin one of the followingranges:

NOTE: The above procedure will calibratethe 0-5 or LEL ranges on the

Gascope Models 60 or 62,respectively. The 0-100 or GAS rangeon the Gascopes normally do notneed to be recalibrated unless theinstrument is damaged, usually bydrawing liquids into the sample inlet.If the Gascope is damaged andrepaired, the 0-100 or gas range mustbe calibrated using the additionalequipment and steps stated in theinstrument Instruction Manual.
