Instruction Manual

3. Operation

When the conductivity monitor is powered on, the display shows all the LCD

segments briefly, and then automatically enters into the measurement mode.

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.)
