9.1.5 Test Channel Analog Output

Many of the TEST functions have an analog voltage associated with them. As a diagnostic aid it is possible to route the various test voltages out the 4th analog output port. Details on using the test channel analog output are in the Troubleshooting Section.

Description

PMT

0 mV

5000 mV

PMT detector output from the preamp. This

DETECTOR

 

 

signal has been amplified and filtered. Since the

 

 

 

instrument is switched and uses AutoZero,

 

 

 

normal values can vary from –100 to 5000 mV.

 

 

 

Wide variations in this signal are normal.

 

 

 

Values should be around 0 mV when sampling

 

 

 

zero air.

 

 

 

 

OZONE FLOW

0 cc/min

1000 cc/min

This signal is the output from the ozone

 

 

 

flowmeter. Values around 1150 mV indicate

 

 

 

zero flow. Typical values for 80cc/min ozone

 

 

 

flow are around 1800 mV. Voltage should be

 

 

 

steady, indicating stable flow.

 

 

 

 

SAMPLE

0 cc/min

1000 cc/min

The sample flow is calculated from the

FLOW

 

 

upstream pressure as measured by the

 

 

 

SAMPLE PRESSURE transducer.

 

 

 

 

SAMPLE

0 “ Hg-Abs

40 “-Hg-Abs

The sample pressure is measured by an absolute

PRESSURE

 

 

pressure meter. The absolute pressure at sea

 

 

 

level is 29.92”-Hg. The exact reading will vary

 

 

 

a few tenths due to passing weather fronts and

 

 

 

daily temperature cycling. The reading will

 

 

 

decrease about 1”-Hg with each 1000 ft gain in

 

 

 

altitude. For example, the absolute pressure at

 

 

 

10,000-ft (3000 m) is about 20”-Hg-A. A

 

 

 

typical value near sea level would be about

 

 

 

4200 mV.

 

 

 

 

RCELL

0 “ Hg-Abs

40 “-Hg-Abs

Like the SAMPLE PRESSURE the RCELL

PRESSURE

 

 

pressure is an absolute pressure measurement.

 

 

 

With the sample pump off, it should read about

 

 

 

atmospheric pressure. With the pump

 

 

 

operating, a typical value is 1300 mV for about

 

 

 

5”-Hg-A reaction cell pressure.
