Temperature coefficient (Ci) [%/K]
With universal inputs in "linear scaling" mode, there is no assessment of the
calibration values.
10.2.1.3 Calibration
Manual entry of calibration values
Calibration values entered incorrectly draw false readings. Accurate
measurements are essential for regulations and threshold monitoring.
If the calibration values are known, you can enter them manually.
This can be, for example, in the temperature-compensated conductivity measurements in
the case where the temperature coefficient of a liquid to be measured is known.
Enter known calibration values manually by going to:
Device menu è Calibration è Select analogue entry è Calibration values
10.2.1.4 Calibration timer
Each analysis input and universal input has its own calibration timer. Calibration timers re
reporting overdue sensor calibrations. Upon successful calibration of the respective input
be calibration timer is reset.
Signalling is done with the following icon on the display:
