PROBE MAINTENANCE

These meters are powered by a 9V battery that is located on the rear 
of the instrument.
When battery symbol is empty a low battery condition is indicated.
When the low battery indication appears, only a few hours of working 
time remains.

It is recommended to replace the battery immediately.
When the battery level is so low that it may cause unreliable measure-
ments, the meter turns off.
Battery replacement must only take place in a nonhazardous area using 
a 9V alkaline battery.
Unscrew the three screws on the rear of the meter, remove the battery 
compartment cover and replace the 9V battery with a new one while 
observing its polarity.
Make sure the battery contacts are tight and secure before replacing 
the cover.

BATTERY REPLACEMENT

PERIODIC MAINTENANCE

Inspect the probe and the cable. The cable used for the connection to the 
meter must be intact and there must be no points of broken insulation 
on the cable or cracks on the probe stem or bulb.
Connector must be perfectly clean and dry. If any scratches or cracks are 
present, replace the electrode. Rinse off any salt deposits with water.
