7.4.1.1 Sensor calibration
If the measured values of the connected sensors do not match
the actual temperatures, a comparison of the sensor values is
possible in the "Sensor Comparison" menu. In this menu, all
sensors connected to the device can be corrected by ±5 K based
on the factory calibration value.
The current measured value, plus or minus the correction made
and the correction itself, appears in the display. The increment of
the compensation is 0.5 K.
ATTENTION
The sensor circuits are calibrated at the factory using precise
measuring equipment. Compensation should only be carried
out if you are sure that the amount of the deviation remains
constant over the entire measurement range.
With sensor compensation, the respective amount must be
noted down, as otherwise the factory setting is no longer
valid and the reference value is lost.
The original factory setting cannot be restored via a reset!
• Compensation in the case of very longer sensor cables
• Constant external temperature influence on sensors
7.4.1.2 Full controller reset
To revert the controller to its state of delivery, a full reset can be
performed. Here, all parameters, values and counters accessible
via the enabled code are reset and the controller is restarted.
Values that are not accessible via the set access code remain in
tact.

7.4.1.3 Controller time correction
In some special cases it may be necessary to adjust the runtime
of the clock integrated in the controller. Please contact the
manufacturer if necessary.
