Mycom CLM 152
Conductive sensors
Caution:
Make absolutely sure you protect
plugs and terminals from moisture.
Moisture leads to inaccurate
measuring results!
Special measuring cable required for connecting conductivity sensors

Note:
•
The instrument has a function to
offset cable length and capacitance
to compensate for cable resistance
(see Chapter 11.5.5 „Determine
cable resistance").
•
A waiting time must be observed
depending on the sensor used
and the medium temperature
(thermal matching) until the sensor
supplies the correct temperature
readings.
