Battery Replacement
When the low battery message “LO BAT” appears on the left corner of the LCD, the 9V
battery has fallen to a critically low voltage level and should be replaced as soon as
possible. The battery compartment cover is located at the bottom rear of the meter. Slide
off the battery compartment cover, change the battery, and replace the compartment
cover.
