8.1 Calibration
Important Note:
Use a thermometer to make sure that the displayed
temperature is accurate.
Important Note:
Enter the sensor data in the configuration menu
before calibration.
Important Note:
The transmitter must be calibrated each time a new
sensor is connected.
Important Note:
If measurements are taken in an area with a cross-
section < 110 mm, use a calibration beaker with the same size and
material (metal/plastic).
Note:
Only qualified personnel should conduct the tasks described in
this section of the manual.
The transmitter is adjusted to the sensor through the calibration. Use
the following methods and passcodes for calibration as described in
During calibration the transmitter remains in the Hold mode for safety
reasons. The loop current is frozen at the value specified in the
