7.4.1.1Sensor calibration

Function 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With sensor compensation, the respective amount must be noted down, as otherwise the factory setting is no longer valid and the reference value is lost.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!

Application • Compensation in the case of very longer sensor cables

• Constant external temperature influence on sensors

7.4.1.2Full 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.

Activation Press the ¢, ¥, ¦ and § keys simultaneously

7.4.1.3Controller 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.
