6.6 Cleaning

If the instrument is unmounted at time of cleaning, disconnect the

instrument from the power source. Close and latch the front-panel access
door. Clean outside surfaces with a soft cloth dampened slightly with
plain clean water. Do not use any harsh solvents such as paint thinner or
benzene.

For panel-mounted instruments, clean the front panel as prescribed

in the above paragraph. DO NOT wipe front panel while the instrument
is controlling your process.

6.7 Troubleshooting

Problem:

Erratic readings of the Oxygen concentration as reported by

the analyzer.

Possible Cause:

The analyzer may have been calibrated in an inaccurate fashion.
