9.2.7 Unstable Zero

Common causes are:

1. Leak in pneumatic system. Perform leak check, see Section 8.7.

2. Miscalibration. See Table 7-1.

3. Light leak - check the sensor module with strong light.

4. Sample lines or sample filter dirty - clean or replace.

5. PMT temp control unstable

9.2.8 Inability to Span

If the SPAN button is not illuminated when attempting to span, that means the reading is outside

of the software gain ranges allowed. In an analog instrument it would be the equivalent to the

span pot hitting the rotation stop.

Here are some things to check:

1. Check the expected span concentration values in CAL-CONC-NOX and CAL-CONC-

NO, and compare them to the values of the calibration span gas being input. They should be

nearly equal.

2. Check the NORM_PMT - TEST function. With NO span gas in the instrument, the value

should be 2x the expected span concentration.

3. Check ET and OT to verify instrument detector and signal processing is working

correctly.

4. If the above do not check out, perform the Factory Calibration Procedure Section 9.1.6.

5. If the PMT voltage is near zero with span gas, check fuse and power to ozone generator.
