Mycom CLM 152
Air set value channel 1
Air set channel 2 (only for difference)
(for difference, carry out for each channel separately)
Preparation
Enter simulation resistance
Measurement running
Display cable resistance
Cable resistance channel 1
Cable resistance channel 2
(only for difference)
Note:
Using the air set calibration function,
you can carry out a zero point
calibration of a connected sensor.
You can carry out the calibration for
Channel 1 and Channel 2 separately
(on the differential instrument).
To perform the calibration, remove
the sensor from the measurement
solution, clean it and hold it in air
without any contact too the liquid.
The Mycom CLM 152 measuring
transmitter then checks the stability
of the measured value. When
stability is reached, the current value
is saved.
This air set value is then transferred
to the standard measured value
calculation.
Reset the air set value by using
"Service data default"!
