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

6.Broken PMT temperature control circuit or broken PMT cooler power supply. Check PMT TEMP - TEST function.

7.Mis-calibration. Check NO/NOx SLOPES in TEST function.

8.Reaction cell pressure too high – leak on vacuum side or bad sample pump. Check RCEL

-TEST function.

9.2.6 Unstable Span

Common causes are:

1.Leak in pneumatic system.

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

3.Instrument not fully warmed up.

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

5.Plugged sample inlet orifice - clean with methanol and sonic cleaner.

6.Defective HVPS - see HVPS test procedure.

7.Bad or defective PMT detector - replace.

8.Reaction cell temp not stable - observe warning messages, or RCELL TEMP in TEST functions. Check diagnostic LED in Power Supply Module for normal cycling.

9.Large variations in ambient temperature - observe warning messages, or BOX TEMP in TEST functions.

10.Large variations in line voltage. - Line voltage should remain within ±10% of nominal.

11.Pump not maintaining steady vacuum - observe warning messages, or RCEL in TEST functions.

12.Sample vent line too short, allowing room air to mix with span gas. Line should be a minimum of 15" long.

13.Calibration gas source unstable.
