sensor.
(1) Turn ON the ALTAIR 5 or ALTAIR 5 IR Multigas Detector in clean,
fresh air.
(2) Verify that readings indicate no gas is present.
(3) Attach regulator (supplied with calibration kit) to the cylinder.

(5) Attach other end of tubing to the instrument.
(6) Open the valve on the regulator, if so supplied.
•
The reading of the ALTAIR 5 or ALTAIR 5 IR Multigas Detector
display should be within the limits stated on the calibration cylinder
or limits determined by your company.
•
If necessary, change cylinder to introduce other calibration.
•
If readings are not within these limits, the ALTAIR 5 Multigas
Detector requires recalibration (see Section 3.9).
