Cause

Remedy

pH electrode:

– pH electrode unsuitable

– Use suitable electrode

– Temperature difference

between buffer and test
sample too high

– Adjust temperature of buffers

or test samples

– Measurement procedure not

suitable

– Follow special procedure

Cause

Remedy

– Operating condition

undefined or EMC load
unallowed

– Processor reset:

Press the

<CAL>

and

<ON/OFF>

keys at the same

time and release them again.
The software version is
displayed.

Cause

Remedy

– Time-out of the interface
