Teledyne API Model 200AU NOX Analyzer Instruction Manual, 02293, Rev. F

7 CALIBRATION & ZERO/SPAN CHECKS

There are several ways to check and adjust the calibration of the M200AU. 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. SPAN CHECKS can be done with either NO only, NO2 only or a mixture of NO and NO2 (GPT).

Zero air used for all calibration procedures, including GPT, should have 1 ppt NO and NO2, less than 1 ppt of major interferents such as SO2, NH3, and hydrocarbons and a dew point of -5oC or less. The 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 7.6.

NOTE

If you are using the M200AU for EPA monitoring, only the calibration method described in Section 7.6 should be used.

NOTE

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.
