Readout for a good battery
The indicator is in the green area, which means this battery is
still good.
Multitesters have many uses, and
one of the handiest is testing
common household batteries.
A weak or dead smoke alarm battery in a fire,
or a dim flashlight bulb during a blackout, can
be downright dangerous. Pull out that multitester
and check those vital batteries so they're
ready when you need them.
Insert the black probe into the (-) terminal,
and the red probe into the (+) terminal.
Rotate the voltage selector switch until it
points to the voltage you're testing, and then
test batteries as shown in Photos 1 and 2.
