M703E Calibrator Operator’s Manual General Troubleshooting & Repair of the M703E Calibrator

Table 11-2: Test Functions - Indicated Failures

TEST FUNCTION DIAGNOSTIC RELEVANCE AND CAUSES OF FAULT CONDITIONS.

PHOTO MEASURE

&

PHOTO REFERENCE

If the value displayed is too high the UV Source has become brighter. Adjust the variable

gain potentiometer on the UV Preamp Board in the optical bench.

If the value displayed is too low:

- < 100mV – Bad UV lamp or UV lamp power supply.

- < 2000mV – Lamp output has dropped, adjust UV Preamp Board or replace lamp.

If the value displayed is constantly changing:

- Bad UV lamp.

- Defective UV lamp power supply.

- Failed I2C Bus.

If the PHOTO REFERENCE value changes by more than 10mV between zero and

span gas:

- Defective/leaking switching valve.

PHOTO FLOW

Gas flow problems directly affect the accuracy of the photometer measurements and

therefore the concentration accuracy of cal gas mixtures involving O3 and GPT mixtures.

- Check for Gas Flow problems.

PHOTO LAMP TEMP

Poor photometer temp control can cause instrument noise, stability and drift. Temperatures

outside of the specified range or oscillating temperatures are cause for concern.

Possible causes of faults are the same as PHOTO LAMP TEMP WARNING from Table 11-1

PHOTO SPRESS

The pressure of the gas in the photometer’s sample chamber is used to calculate the

concentration of O3 in the gas stream. Incorrect sample pressure can cause inaccurate

readings.

- Check for Gas Flow problems. See Section Table 11-1.

PHOTO STEMP

The temperature of the gas in the photometer’s sample chamber is used to calculate the

concentration of O3 in the gas stream. Incorrect sample temperature can cause inaccurate

readings.

Possible causes of faults are:

- Bad bench lamp heater

- Failed sample temperature sensor

- Failed relay controlling the bench heater

- Failed Relay PCA

- I

2C Bus malfunction

- Hot Lamp

PHOTO SLOPE

Values outside range indicate:

Contamination of the Zero Air or Span Gas supply.

Instrument is miss-calibrated.

Blocked Gas Flow.

Faulty Sample Pressure Sensor or circuitry.

Bad/incorrect Span Gas concentration.

PHOTO OFFSET Values outside range indicate:

Contamination of the Zero Air supply.

TIME

Time of Day clock is too fast or slow.

To adjust see Section 6.7.2.

Battery in clock chip on CPU board may be dead.
