5.2.1Test Functions

NOTE

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

XXXXis displayed, that indicates an off scale and therefore meaningless reading.

To use the TEST functions to diagnose instrument faults, refer to Troubleshooting Section 9.1.

Range

This is the range of the instrument. Electronically, there is only one physical range. The range of the instrument is just the software expanding various portions of the single physical range to fill the selected analog output voltage range. In standard configuration there is one range for all 3 outputs.

Independent range option allows different ranges for each output. When enabled, there will be three range values displayed, NO, NOx and NO2.

Auto range mode allows a low range and high range. The M200AU will automatically switch to the other range dynamically as concentration values require. The TEST values will show the range the instrument is currently operating in, and will dynamically display the alternate range as the range changes occur.

NOTE

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

Independent ranges are mutually exclusive.

Stability

The instrument noise is computed using the standard deviation of the last 10 minutes of data, with the value being computed at the end of each NO/NOx cycle. It is computed for the NOx channel only. The stability value only becomes meaningful if sampling a constant concentration for more than 10 minutes. The value should be compared to the value observed in the factory check-out.

The Stability reading on the front panel TEST functions is different than the STABIL reading found in the DAS. Check the DAS in Section 5.3.3 for more information on the STABIL - DAS.
