Error message/Warning Condition Remarks
Temperature range restricted For the chosen temperature
xx – 100 ° C coefficient α , a correct reading
can only be obtained for the
displayed temperature range
Temperature interval incorrect ∆ temperature ≥ 10.0 ° C
∆ temperature ≤ 50.0 ° C
Complete Operating Menu / Description
Calibration of temperature coefficient α
The temperature coefficient α is determined again by means of a two point calibration. During the
calibration, the metering is reduced to the set basic load and control stops. The limit value monitor and the
fault diagnosis system are reset. The standard signal of the measured value or correction value output is
reduced to 0/4 mA.
IMPORTANT
Only values determined at 25 ° C may be entered as conductivity values. The calibration
must be carried out with the same solution at both temperatures.
