Field Calibration Procedure

1) Zero gas ranges before attempting calibration. See

previous section ZEROING THE INSTRUMENT

for details.

2) Make sure that the instrument pump is running and

the  gas  range  selected  is  compatible  with  the

calibration gas.

Note: A single press of Button One 

 toggles the pump

Off / On.

3) Remove  the  cap  from  calibration  gas  cylinder.

Make sure that the regulator valve is in the fully

closed position (Off) then connect the gas regulator

to the gas cylinder (push down gently and tighten

clockwise, hand tight). See Figure B-5 for details.
