XIII.
CELL CHECK
The cell check verifies the cleanliness of the conductivity/TDS/resistivity
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. However, when testing high purity water in
resistivity (RES) mode improved accuracy may be desired. No matter
what a manufacturer claims, a sensor can and will become contaminated
or coated; therefore require cleaning. A true 4-wire sensor, as in the
Ultrameter II, helps to mitigate contamination, but NO SENSOR IS
100% IMMUNE.

If cell is clean, Good will
momentarily be displayed
(see Figure 22). If cell is
dirty, CELL cLn will be
displayed (see Figure 23),
(ref. Cleaning Sensors,

XIV. AUTO OFF
Auto off allows the user to adjust the
time the instrument is ON (up to 75
seconds) after each press of a key.
Default time is 15 seconds with 60
seconds in CAL (calibration) mode.
