Calibration And Zero/Span Checks - Teledyne 200A Instruction Manual

Teledyne API Model 200A NO

7 CALIBRATION AND ZERO/SPAN CHECKS

There are several ways to check and adjust the calibration of the M200A. These different
methods are summarized in Table 7-1. In addition, all of the methods described in this section
can be initiated and controlled via the RS-232 port.
We strongly recommend that SPAN CALIBRATION be done with NO span gas, although it is
possible with NO
done with either NO only, NO
Zero air used for all calibration procedures, including GPT, should have < .1 ppb NO or NO
less than 1 ppb of major interferents such as SO2 and NH3, and a dew point of -5
calibration gasses should be from a reliable supplier, since the quality of the tank concentration
values ultimately determines the accuracy of the analyzer. EPA protocol calibration gasses
should be used for EPA monitoring, see Section 7.8.
If you are using the M200A for EPA monitoring, only the
calibration method described in Section 7.8 should be used.
If there are any problems completing any of the following procedures,
refer to Section 9.2.8 and 9.2.9 - Unable to Span or Zero.
