MAINTENANCE
Routine maintenance of the unit is confined to cleaning the sensor and changing the batteries.
Cleaning the Sensor
Nonconductive coatings (oil and grease) can cause noisy readings or conductivity lost errors. Clean
the sensor with soap and water. If a problem still persists, clean the electrodes with a very fine grit
(600) sandpaper. Do not use hydrocarbon solvents.
Changing Batteries
A low battery flag is displayed when a low battery voltage is detected. Check the battery change guide
(Page 13) for battery-life estimates.
The battery compartment (Figure 3) is located in the bottom of the meter. To change the batteries,
unscrew the three captive screws on the bottom cover. Remove cover and replace the batteries (two D
size). Reinstall the bottom cover.
