4) Repeat steps 2 and 3 until all gas ranges have

been zeroed.

5) Proceed to FIELD CALIBRATION PROCEDURE to

calibrate the instrument.

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 Switch 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.
