5.4 Programming the transmitter

For detailed information regarding transmitter programming, please refer to the user manual
delivered with the transmitter.
5.4.1 Set the measurement type
Make sure that both switches on the conductivity module of the transmitter are correctly configured
on position K (to indicate a 2 electrode probe).
5.4.2 Set the cell constant
On the PROGRAMMING-MEASURE-PROBE menu, set the cell constant value (K) of the probe.
This value is indicated on the probe certificate and is determined with a precision of < 2% in
compliance with standards ASTM D 1125 and ISO7888.
5.4.3 Set the frequency
On the PROGRAMMING-MEASURE-PROBE menu, set the probe frequency in relation to the
conductivity:
-1
K (cm )
0.01
0.1
1.0
Whenever possible, it is preferable to operate in the Average conductivity zone (and therefore to
choose the correct type of probe).
Low conductivity zone: To avoid causing a parallel capacitance, do not combine a long length of
cable with a high measurement frequency (measurement of conductivity too high). If using a long
length cable (> 20 meters) set the frequency to 70 Hz.
Average conductivity zone: No particular precautions are required. Set the frequency to 1 kHz.
