5.6 Measuring Range Settings
The conductivity controller has 6 different measuring ranges. You need to select a
range which is the most suitable for conductivity reading of your applications/samples.
The factory default is 2000
μ
S (0 to 2000
μ
S/cm).
The measuring range you select here will affect the way the controller behaves in the
measurement mode and calibration mode. In measurement mode, if the conductivity
reading of the controller is above the selected measuring range, the LCD shows “Or”
(over range) error. In calibration mode, the controller adjusts calibration tolerance
based on full scale of the selected measuring range. The calibration is carried out
only for the selected measuring range.
WARNING:
If you change the measuring range of the controller after calibration is
done, the controller will reset back to its factory default calibration.
