Teledyne API Model 200A NOX Analyzer Instruction Manual, 02246, Rev. G, DCN 5247 9.1.6 Factory Calibration Procedure The Factory Cal procedure balances the PMT, preamp, and software gain factors so the instrument has optimum noise, linearity, and dynamic range. It should be used when you are unable to zero or span the instrument, when the slope and offset values are outside of the acceptable range, or when other more obvious reasons for problems have been eliminated.
Teledyne API Model 200A NOX Analyzer Instruction Manual, 02246, Rev. G, DCN 5247 9. Calculate the expected NORM PMT mV reading. For ranges up to 2000 ppb, multiply the expected span value by 2 to get the mV reading. For ranges 2001 to 20000 ppb, multiply the expected span value by .2 to get the mV reading. In this example the expected span gas concentration is 400 ppb and therefore the expected voltage is 800 mV. As an alternate method, the voltage can be determined from the graph in Table 9-9-7.

Permeation tube or cal gas tank exhaustion. 5. Leak in NO/NOx or AutoZero switching valves. 6. Loose pneumatic fittings. 9.2.1 AC Power Check 1. Check that power is present at main line power input. Verify that correct voltage and frequency is present.
Teledyne API Model 200A NOX Analyzer Instruction Manual, 02246, Rev. G, DCN 5247 9.2.3 No Response to Sample 1. 2. Confirm correct operation of analog output by performing Analog Output Step Test in Section 9.1.3.5. Confirm general operation of analyzer. A. Check for AC Power, Section 9.2.1. B. Do flow checks, Section 9.2.2. C. Confirm that sample gas contains NO or NO2. 3. Check instrument electronics. A. Do ELEC TEST procedure in DIAGNOSTIC menu Section 9.1.3.2. B.
Teledyne API Model 200A NOX Analyzer Instruction Manual, 02246, Rev. G, DCN 5247 9.2.4 Negative Output 1. Mis-calibration. The 'zero' gas that was used to zero the M200A contained some NO gas that is, it had more NO gas than that of the sample air. May also be caused by doing a zero calibration using ambient air. If NO/NOx OFFSET - TEST functions are greater than 150 mV, reaction cell contamination is indicated. 2. Corruption of the AutoZero filter.
Teledyne API Model 200A NOX Analyzer Instruction Manual, 02246, Rev. G, DCN 5247 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.
Teledyne API Model 200A NOX Analyzer Instruction Manual, 02246, Rev. G, DCN 5247 9.2.7 Unstable Zero Common causes are: 1. Leak in pneumatic system. Perform leak check, see Section 8.9. 2. Miscalibration. See Table 7-7-1. 3. Light leak - check the sensor module with strong light. 4. If equipped with IZS, zero air scrubber exhausted - replace charcoal and Purafil. 5. Sample lines or sample filter dirty - clean or replace. 9.2.
Teledyne API Model 200A NOX Analyzer Instruction Manual, 02246, Rev. G, DCN 5247 9.2.9 Inability to Zero If the ZERO button is not illuminated when attempting to zero, that means the reading is outside of the software gain ranges allowed. In an analog instrument it would be the equivalent to the zero pot hitting the rotation stop. Check the following: Select the PMT - TEST function. With zero gas going into the instrument, the value should be less than 150 mV, typically less than 50 mV.
Teledyne API Model 200A NOX Analyzer Instruction Manual, 02246, Rev. G, DCN 5247 9.2.10 Non-Linear Response Common causes are: 1. Leak in pneumatic system, see Section 8.9. 2. High zero background - the PMT TEST function should be near 50 mV with zero gas. Readings above 100 mV indicate a light leak, contaminated reaction cell, bad zero gas, or wet air coming into the ozone generator. If the reading is not less than 150 mV, the instrument will not zero or span properly. Check Section 9.2.9. 3.
Teledyne API Model 200A NOX Analyzer Instruction Manual, 02246, Rev. G, DCN 5247 9.2.11 Slow Response 1. Contaminated or dirty sample delivery pneumatics. A. Dirty/plugged sample filter or sample lines. B. Dirty reaction cell. 2. Sample inlet line too long. 3. Wrong materials in contact with sample - use glass, stainless steel or Teflon. 4. Sample vent line located too far from instrument sample inlet. Locate sample inlet vent as close as possible to analyzer. 5.
