on the spare electronics module and the serial number of the sensor
correspond.
Then all application-specific settings must be entered again. Carry
out a fresh setup after exchanging the electronics or load the stored
data of the setup.

First of all, you have to transfer the device-specific sensor data to the
new electronics module.
You can download these individual, device-specific data of your sen-
sor from our homepage.
Under "Instrument search (serial number)" you can download the
specific sensor data as XML file with the sensor serial number directly
to the sensor.
After the transfer of the sensor data, you have to verify the correct
transmission by means of a check sum. Only then, the instrument will
be ready for operation, again.
You can find the detailed process of the electronics exchange in the
supplementary instructions "
Electronics module
".
Then all application-specific settings must be entered again. Carry
out a fresh setup after exchanging the electronics or load the stored
data of the setup.
If you saved the parameter settings during the first setup of the sen-
sor, you can transfer them to the replacement electronics module. A
fresh setup is then not necessary.
10.6 Exchange or shorten cable/rod
The cable or rod (meas. part) of the probe can be shortened, if neces-
sary. To loosen the rod or cable you need a fork spanner with spanner
width 13.
1. Loosen the rod or cable by applying a fork spanner to the flat
surfaces (SW 13), provide counterforce with another fork spanner
(SW 13)
2. Unscrew the loosened rod or cable manually.
3. Place the enclosed new double washer onto the thread.
Caution:
Make sure that the two components of the double washer remain
together.
4. Screw the new rod and the new cable manually to the thread on
the process fitting.
5. Exert counterforce with the second fork spanner and tighten
the measuring rod or cable on the flat surfaces with a torque of
20 Nm (15 lbf ft).
