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.
