The mode indicator ‘
MEAS
’ at the top of the display indicates that the conductivity
controller is in measurement mode. The upper alpha-numerical display shows the
measured conductivity value, while the lower display shows the temperature value.
The controller has six selectable measuring ranges. The unit of measurement and
resolution of the conductivity reading depend on the selected measuring range. If
the controller 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 controller 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.)
