Care
• If the function selector is set to
R
××××
1K
Ω
, multiply that reading by
1000 to compute the resistance.
For example, if the needle points
to 1, the resistance is 1000 ohms
(1
×
1000 = 1000
Ω
).
Hint: If you are identifying cathode
and anode ends or the type of transis-
tor (PNP or NPN), the actual polarity
of the multimeter's voltage is the op-
posite of the polarity suggested by the
test probes' color. The red test probe
is the negative source, and the black
test probe is the positive source.

Care
Keep the multimeter dry; if it gets wet,
wipe it dry immediately. Use and
store the multimeter only in normal
temperature environments. Handle
the multimeter carefully; do not drop
it. Keep the multimeter away from
dust and dirt.
Modifying or tampering with the multi-
meter’s internal components can
cause a malfunction and might invali-
date its warranty. If your multimeter is
not performing as it should, take it to
your local RadioShack store for assis-
tance.
CLEANING
To keep the multimeter looking new,
occasionally wipe it with a cloth slight-
ly dampened with water. Do not use
harsh chemicals, cleaning solvents,
or strong detergents to clean the mul-
timeter.
WARNINGS:
• DO NOT LET ANY WATER DRIP
INSIDE THE MULTIMETER
WHILE CLEANING IT.
• MAKE SURE THAT THE MULTI-
METER IS COMPLETELY DRY
BEFORE USING IT.
