Sample Flow

The SAMPLE FLOW test function is computed from the pressure measured up-stream of the sample flow orifice. The pressure down-stream of the orifice is also checked to assure the assumptions of the equation are valid. This will register variations in flow caused by changes in atmospheric pressure, but will not detect a plugged sample flow orifice. The nominal value is 1000 ± 100 cc/min.

Ozone Flow

The OZONE FLOW test function is directly measured by a solid state flow meter. Variations in this value indicate variations in ozone flow. The nominal value for ozone flow is 80 ± 15 cc/min.

PMT Voltage

The PMT VOLTAGE measures the PMT signal at the output of the preamp board. The waveform of the PMT voltage can be complex, and vary from near 0 mV when zero gas is in the reaction cell to 5000 mV when a high concentration of NOx is being measured. If the PMT reading is consistently 5000 mV, that indicates an off-scale reading. Typical readings bounce around, which is normal.

Normalized PMT Voltage

Like the PMT Voltage TEST function above, the NORMALIZED PMT VOLTAGE measures the PMT signal at the output of the preamp board. The difference is that several normalization functions are applied to this signal before it is displayed. The most important is the temperature and pressure compensation factors. If NORM PMT is used as suggested in the Factory Calibration Procedure (Section 9.1.6) the M200AU will be correctly calibrated.

PREREACT Voltage

This test measurement is the Pre-reactor voltage. It indicates the most recent reading from the Pre-reactor circuit. The units are mV and readings up to 1000 are considered normal.

High Voltage Power Supply (HVPS)

The HVPS reading is a measure of the scaled-up HVPS programming voltage. The voltage used to set the HVPS output is generated on the Preamp board. Its value is between 0 and 1 volt, corresponding to a voltage of 0 to 1000 volts out of the HVPS. The HVPS front panel TEST measurement should be greater than 450 volts and will typically be 500-800 V.
