cELL chEcK

The cell check verifies the cleanliness of the conductivity/MIN/

SALT/TDS sensor. In normal use the cell may become dirty or

coated and require cleaning. If the display is showing “.00” when

the cell cup is dry, the sensor is probably clean. No matter what a

manufacturer claims, a sensor can and will become contaminated or

coated and, therefore, require cleaning. A true 4-wire sensor, as in

P
