BATTERY REPLACEMENT

The meter displays the remaining battery per-

centage when turned on. When the level is

below 5%, the battery symbol on the bottom

left of the LCD blinks to indicate a low battery condition.

If the battery level is low enough to cause erroneous readings, the Battery

Error Prevention System (BEPS) turns the meter

off. When the battery

needs to be replaced, remove the cover on the rear of the meter and replace

the rundown battery with a new

one, while paying attention to

the correct polarity. Reattach

the back making sure that the

gasket is in place and tighten

the 3 screws to ensure a good

seal.

Replacement should take

place in a non-hazardous area

using a 9V alkaline battery.
