When the remaining battery life is less than 10% the battery tag
blinks on the display to warn the user.
If the battery level is low enough to cause
erroneous readings, the Battery Error Preven-
tion System (BEPS) turns the meter off.
Immediately replace the batteries with new
ones.
Battery replacement must only take place in a non-hazardous
area.
The batteries are accessed by opening the battery compartment
cap on the bottom of the instrument.
Replace the three 1.5V AAA alkaline
batteries located in the battery
compartment, observing the polarity
on the rear of the instrument.
Reattach the battery compartment
cap making sure that the gasket is
in place.
