The
symbol will appear on the LCD display when the
voltage drops below proper operating range. This indi-
cates that the batteries need to be changed.
It is recommended to replace both batteries at the same
time.
• The meter must be in the OFF position and discon-
nected from any circuit or input.
• Place the meter face down and loosen the battery
cover screw with a flat head screwdriver.
• Replace the batteries with two fresh 1.5V AAA (LR03)
batteries.
• Replace the battery compartment cover and tighten
down the screw.
