XVI. 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 and will
therefore require cleaning. A true 4-wire sensor, as in the Dialysate Meter,
helps to mitigate contamination, but NO SENSOR IS 100% IMMUNE.

repeatedly
until you pass the “FAC SEL”
location. The display will show
“CELL ch” (see Figure 20).

to test.
If cell is clean, “Good” will
momentarily be displayed.
(See Figure 21.) If cell is dirty,
“CELL cLn” will be displayed
(see Figure 22). (Ref.
Cleaning Sensors, pg. 34.)
XVII. 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 in
measurement mode and 60
seconds in “CAL” (calibration) mode.
