when the voltage drops below proper operating
range. This indicates that the batteries need to
be changed.
It is recommended to replace both batteries at the
same time.

disconnected from any circuit or input.
• Place the meter face down and loosen the
battery cover screw with a flat head screw-
driver.
• Replace the batteries with two fresh 1.5V AAA
(LR03) batteries.
