8 Sensor Calibration

Note: For best process calibration results observe the following points. Take grab sample as
close as possible to the measurement point of the sensor. Measure the sample at process
temperature.
For a detailed description of the "Process", "1-Point" and "2-Point" calibration methods see
Operation Manual of the M400 transmitter. It is also possible to connect pre-calibrated sensors,
calibrated via iSense software.
As soon as the calibration is in progress no other calibration can be started.
Sensor Calibration Menu c
After every successful calibration different options are available. If "Adjust", "SaveCal" or "Cali-
brate" is chosen, the message "Calibration saved successfully! Reinstall sensor" is displayed.
Press "Done".

Analog sensors
Calibration values are stored in the
transmitter and used for the measure-
ment. Additionally, the calibration values
are stored in the calibration data.
The function "Calibrate" is not applicable
for analog sensors.
Calibration values are discarded.
ISM (digital) sensors
Calibration values are stored in the sen-
sor and used for the measurement. Ad-
ditionally, the calibration values are
stored in the calibration history.
Calibration values are stored in the cali-
bration history for documentation, but
not used for the measurement. The cali-
bration values from the last valid adjust-
ment are used for the measurement.
Calibration values are discarded.
