5.3 Temperature Settings
Automatic Temperature Compensation (ATC):
The conductivity value of a sample is affected by temperature. Use ATC feature of
the monitor to compensate for conductivity changes when the temperature of the
sample or process liquid fluctuates. Connect a separate temperature probe
(Pt100/pt1000) to the monitor if an integrated conductivity/Temperature probe is not
available.
Manual Temperature Compensation (MTC):
Set the monitor to MTC (disable ATC) when the temperature of sample or process
liquid is constant and a temperature probe is not available. If you disable ATC, the
monitor allows you to set your process temperature (P.ºC) and calibration
temperature (C.ºC). This allows calibration at a different temperature other than the
process temperature. Example: Setting calibration temperature of 25°C lets you
calibrate using standard solutions at 25°C, even if your process temperature is
different from 25°C.
