Chapter 4
Calibration
Introduction
As with any type of gas monitor, the only true check of its performance
is to apply gas directly to the sensor. The frequency of the calibration
gas test depends on the operating time and exposures of the sensors.
New monitors should be calibrated more often until the calibration
records prove stability. The calibration frequency can then be reduced to
the schedule set by the safety officer or plant manager.
Perform the calibration procedure regularly and maintain a log of
calibration adjustments. Calibration frequency may increase for a variety
of reasons. If calibration cannot be performed at any step, STOP;
consult MSA at 1-800-MSA-INST.
