Teledyne 9110T instruction manual Electrical Test, Ozone GEN Override, Flow Calibration

Model 9110T NOx Analyzer Setup Menu

that the analyzer measures only the light coming from the LED, the analyzer should be supplied with zero air. The optic test should produce a PMT signal of about 2000±1000 mV.

Section 12.7.12.1 presents instructions for use in troubleshooting and service.

IMPORTANT	IMPACT ON READINGS OR DATA
	This is a coarse test for functionality and not an accurate calibration tool.
	The resulting PMT signal can vary significantly over time and also
	changes with low-level calibration.

5.9.6. ELECTRICAL TEST

The ELECTRICAL TEST function creates a current, which substitutes the PMT signal, and feeds it into the preamplifier board. This signal is generated by circuitry on the pre-amplifier board itself and tests the filtering and amplification functions of that assembly along with the A/D converter on the motherboard. It does not test the PMT itself. The electrical test should produce a PMT signal of about 2000 ±1000 mV.

Section 12.7.12.2 presents instructions for use in troubleshooting and service.

5.9.7. OZONE GEN OVERRIDE

This feature is used to manually turn the ozone generator off and on. Read Section 13.2.3 to understand the ozone generator, and refer to Section 12.7.15.1 for instructions on using the override feature in troubleshooting and service.

5.9.8. FLOW CALIBRATION

This function is used to calibrate the gas flow output signals of sample gas and ozone supply. Section 9.7 presents instructions for flow calibration. Used to adjust the gas flow calculations made by the CPU based on pressure and flow sensor readings.
