4 MEAS switch

5 ON/OFF switch Turns ON/OFF the meter. 6 CAL switch 7 Waterproof gasket Makes the meter waterproof.

Place a sample on this sensor. This sensor consists of a liquid junction (A) and response membrane (B). Both A and B must be covered with the sample.

Shields the sensor from light, which affects the sensor. Close the light shield cover before starting measurement. If using the sampling sheet holder cover (refer to page 15), shield the flat sensor from light with an alternative.

Switches the calibration mode to the measurement mode, activates/deactivates the reading locking function in the measurement mode, and starts/applies settings in the special setting mode.

Starts calibration, and switches items/settings in the special setting mode.

Blinks until the measured value is stabilized, and lights steadily when the measured value is settled, while the reading locking function is active.

Blinks during calibration, and lights steadily when calibration is finished.

Lights up when the batteries are low and need to be changed.

Blinks when the measuring environment temperature does not meet the specified operating temperature (5qC to 40qC).

Displays a measured, set, or status value. A unit symbol lights up corresponding to the valu e displayed

on the measured value display (14). “%” lights up for salt concentrations.
