Troubleshooting & Service
11.7.2.8. PMT HARDWARE CALIBRATION (FACTORY CAL)
258
21. Power up the analyzer and verify the basic operation of the analyzer using the
ETEST and OTEST features (refer to Section 5.9.4 and 5.9.5) or by measuring
calibrated zero and span gases.
22. Allow the instrument to warm up for 60 minutes.
23. Perform a PMT Hardware calibration (refer to Section 11.7.2.8).
24. Perform a zero point and span calibration (refer to Section 9).
The sensor module hardware calibration adjusts the slope of the PMT output when the
instrument's slope and offset values are outside of the acceptable range and all other
more obvious causes for this problem have been eliminated.

1. Set the instrument reporting range type to SNGL (refer to Section 5.4.3.1).
2. Perform a zero–point calibration using zero air (refer to Section 9).
3. Let the instrument stabilize by allowing it to run for one hour.
4. Adjust the UV Lamp (refer to Section 11.7.2.5).
5. Perform a LAMP CALIBRATION procedure (refer to Section 5.9.6).
6. Locate the Preamp PCA (refer to Figure 11-16).
7. Locate the Following Components On the Preamp PCA (Figure 11-17):
8. HVPS coarse adjustment switch (Range 0-9, then A-F).
9. HVPS fine adjustment switch (Range 0-9, then A-F).
10. Gain adjustment potentiometer (Full scale is 10 to 12 turns).
11. Set the HVPS coarse adjustment to its minimum setting (0).
12. Set the HVPS fine adjustment switch to its maximum setting (F).
