5.2.1. Test Functions

NOTE

In any of the following TEST functions, if a value of

XXXX is displayed, that indicates an off scale and

therefore meaningless reading.

TEST functions allow the operator to examine several important operating parameters of the
M200AH to verify correct Analyzer operation. If faults are discovered, refer to Troubleshooting
Section 9.

Range (RANGE)

This is the Range of the instrument. In single range mode there is one range for all 3 rear panel
analog outputs.

The AutoRange option allows 2 different ranges for each channel, and will automatically switch
to the other range dynamically as concentration values require. By selecting Remote AutoRange,
the range change can be controlled remotely. The TEST values will show the range the
instrument is currently operating in, and will dynamically display range change information
when necessary.

Independent range option allows different ranges for each output. When enabled, there will be
three range values displayed, NO, NO

and NO

NOTE

Each of the range modes Single range, Auto range, and

Independent ranges are mutually exclusive.

Oxygen Sensor Range (O

RANGE) (Option)

For units equipped with the O

Sensor Option, this is the Full Scale Range of the rear panel O

analog output.
