Sensor Calibration

h
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.
Via the display of the transmitter, configuration tool, asset-management-tool or HART handheld
terminal you can calibrate the sensor with the "Process", "1-Point" or "2-Point" calibration
method. For the calibration methods see Operation Manual of the M400 transmitter. Via iSense
software you can calibrate the sensor with the "1-Point" or "2-Point" calibrate method. See
Operation Manual of the iSense software.
As soon as the calibration is in progress no other calibration can be started.
Sensor Calibration Menu
After every successful calibration the options "Adjust", "Calibrate" and "Abort" are available.
After selection one of these options the message "Re-install sensor and Press [ENTER]"
appears.
After pressing [ENTER] the M400 returns to the Measurement mode.

Analog sensors
Calibration values are stored in the
transmitter and used for the measure-
ment. Additionally, the calibration val-
ues are stored in the calibration data.
The function "Calibrate" is not applica-
ble for analog sensors.
Calibration values are discarded.
ISM (digital) sensors
Calibration values are stored in the
sensor and used for the measurement.
Additionally, the calibration values are
stored in the calibration history.
Calibration values are stored in the
calibration history for documentation,
but not be used for the measurement.
The calibration values from the last
valid adjustment are further used for
the measurement.
Calibration values are discarded.
