5.4 Measuring Range Settings
The conductivity monitor has 5 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 µS (0 to 2000 µS/cm).
The measuring range you select here will affect the way the monitor behaves in the
measurement mode and calibration mode. In measurement mode, if the conductivity
reading of the monitor is above the selected measuring range, the LCD shows “Or”
(over range) error. In calibration mode, the monitor 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 monitor after calibration is
done, the monitor will reset back to its factory default calibration.
