For pH probes only:
Temperature measurement.

Impedance measurement (the blue wire from the transmitter's "liquid earth"): programme the control frequency and the upper and lower
limits (refer to the instructions for the 9135 transmitter):
Glass impedance: 50 Mohm - 500 Mohm
Reference impedance: 1…100 kohm
