Teledyne API Model 200A NOX Analyzer Instruction Manual, 02246, Rev. G, DCN 5247
5.2.2.6 Automatic Converter Efficiency Compensation
The M200A can automatically compensate the NOx and NO2 readings for the molybdenum
converter efficiency. There are 2 ways to enter the converter efficiency into the instrument. The
first is to just type in the converter efficiency using the CAL-CONC-MOLY-SET menu. The
second method is to have the M200A compute the efficiency using the CAL-CONC-MOLY-
CAL menu. See the Calibration Section 7.8.6 - Molybdenum Converter Efficiency for details.
To disable the compensation, press CAL-CONC-MOLY-SET and enter 1.0000 as the efficiency.
Factory default is 1.0000.
5.3 Set-Up Mode

5.3.1 Configuration Information (CFG)

This menu item will tell if the installed software has factory special features or other non-
standard features. If you call Teledyne API service you may be asked for information from this
menu.

5.3.2 Automatic Calibration (AutoCal)

The AutoCal feature allows the M200A to automatically operate the Zero/Span Valve or IZS
option to periodically check its calibration. Information on setting up AutoCal is in Section 6.4.

5.3.3 Data Acquisition System (DAS)

The M200A contains a flexible and powerful built in data acquisition system (DAS) that enables
the analyzer to store concentration data as well as diagnostic parameters in its battery backed
memory. This information can be viewed from the front panel or printed out through the RS-232
port. The diagnostic data can be used for performing “Predictive Diagnostics” and trending to
determine when maintenance and servicing will be required.
The logged parameters are stored in what are called “Data Channels.” Each Data Channel can
store multiple data parameters. The Data Channels can be programmed and customized from the
front panel. A set of default Data Channels has been included in the M200A software. For more
information on programming custom Data Channels, a supplementary document containing this
information can be requested from Teledyne API.
5.3.3.1 Data Channels
The function of the Data Channels is to store, report, and view data from the analyzer. The data
may consist of NO, NOx, NO2 concentration, or may be diagnostic data, such as the sample flow
or reaction cell pressure.
