The mode indicator ‘ MEAS ’ at the top of the display indicates that the
conductivity monitor is in measurement mode. The upper alpha-numerical
display shows the measured conductivity value, while the lower display
shows the temperature value.
The monitor has five selectable measuring ranges. The unit of measurement
and resolution of the conductivity reading depend on the selected measuring
range. If the monitor reads a conductivity reading beyond the selected
measuring range, the display shows ‘Or’ (over range) error indicator.
NOTE: To guarantee accurate readings, the measuring system (the
conductivity monitor and the sensor) must be calibrated regularly.
From measurement mode you can access:
•
Calibration mode (by pressing CAL key)
•
Setup mode (by pressing ENT key)
For more details, refer section 4 for Calibration mode and section 5 for Setup
mode.)
