Xiii. 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
the P
OOL
P
RO
, helps to mitigate contamination, but NO SENSOR IS
100% IMMUNE.
