Diagnostic (calibration of sensor)
Here you make the calibration of the sensor. If the sensor is operating in one of the predefined liquid it is delivered with a
calibration and does normally not need further calibration. If you need higher accuracy the sensor can be calibrated
Here you can see and change the zero
calibration.
The value is normally calculated based
on an automatic calibration and should
not be changed
Here you can see
the actual meas-
urement value
Use this button to
make the zero
calibration
Wire level sensor manual 05
Warning: If you make a calibration to known level the accuracy at the
lowest 20 % will become poor – we recommend not to use this functionality.
The button and the field is used to make a calibration to a known level be-
tween 20 and 100%. This will make the sensor more accurate around the cali-
bration point, but outside the accuracy will be reduced, compared to the cali-
bration obtained by filling in the information about length, refrigerant , tem-
perature and standpipe.
Here you can see and change the SPAN
which is a part of the calibration
The value is normally calculated based
on an automatic calibration and should
not be changed
