Diagnostics and troubleshooting

9.1

General troubleshooting

When troubleshooting, the entire measuring point must be taken into account:

• Transmitter

• Electrical connections and cables

• Assembly

• Spectrometer
The possible causes of error in the following table relate mainly to the spectrometer.

Problem

Check

Solution

Nothing displayed, no
reaction from the
spectrometer

• Power supplied to transmitter?
• Spectrometer connected correctly?
• Buildup on optical windows?

‣

Connect mains voltage.

‣

Establish correct connection.

‣

Clean the spectrometer.

Display value too high or
too low

• Buildup on optical windows?
• Spectrometer calibrated?

‣

Clean the windows.

‣

Calibrate the spectrometer.

Display value fluctuating
greatly

• Air bubbles in the measurement

gap?

• Is the mounting location correct?

‣

Clean the windows.

‣

Select a different mounting location.

‣

Adjust measured value filter.

Measured value drift

Buildup on optical windows?

‣

First clean the spectrometer.

‣

Record the reference spectrum.

Pay attention to the troubleshooting information in the Operating Instructions for the

transmitter. Check the transmitter if necessary.
