1 Notes These calibration instructions and the calibration set (resistance decade) that comes with the replacement sensor are provided exclusively for the purpose of calibrating the replacement sensor! If a transmitter is supplied together with a sensor, then this combination is factory-calibrated. It is not possible to recalibrate such a combination using these calibration instructions and the calibration set.

“Installation” in the Operating Manual B20.2755.0 (Part No. 00444870). 3 Calibration 3.1 Requirements - The supply voltage for the CTI-500 must be present. see chapter "Installation" in the Operating Manual B20.2755.0 (Part No. 00444870). - The sensor must be connected to the transmitter.

selection with the key. - LEDs K1 and K2 blink. Pass the cable of the calibration set through the sensor opening. The calibration program will ask you to connect the first calibration resistor. The first calibration resistor is an open loop, as shown in the picture.

If an error occurs (e.g. if the plug of the calibration set was inserted in the wrong socket), a message will be displayed. The calibration must then be ended by pressing the key. EXIT The old calibration data (prior to the calibration attempt) are retained and will continue to be used.

Calibration is finished after step 5. Press the key for about 5 seconds - the calibration values are accepted and the procedure is concluded. The calibration values can be rejected by pressing the key. In this case, the transmitter will operate with EXIT the old values.
