unstable, and/or
measurement method is out
of control; take corrective
action such as obtaining new
calibration gas.

Perform at least once every
quarter or anytime a level
span check indicates a
discrepancy, or after
maintenance which may
affect the calibration; Subsec
2.5 (Q.A. Manual) Repeat the calibration
10.1.2. Data Recording Device
Either a strip chart recorder, data acquisition system, digital data acquisition system
should be used to record the data from the Mode; 6200T RS-232 port or analog outputs.
If analog readings are being used, the response of that system should be checked against
