A WORD ABOUT
SAFETY
We have taken every precaution in
designing this multimeter to ensure
that it is as safe as we can make it.
But safe operation depends on you,
the operator. We recommend that
you follow these simple safety rules:
• Never apply voltages to the mul-
timeter that exceed the limits
given in “Specifications” on
Page 6. Never apply more than
500V DC or 500V RMS AC
between any input terminals or
between an input terminal and
ground.
• Use extreme caution when work-
ing with voltages above 40V.
Always disconnect power from
the circuit you are measuring
before you connect test leads to
high-voltage points.
• Never connect the test leads to a
source of voltage when the func-
tion selector is set to

.
• Always discharge any capacitors
of the circuit under test before
you attach test leads.
• Always turn off power and dis-
connect the test leads from the
circuit you are testing before you
replace the multimeter’s battery.
• Never operate the multimeter
unless its battery compartment
cover is in place and fully closed
with the screw fully tightened.
• Because many AC/DC sets have
a potentially hot chassis, be sure
the top of your workbench and
the floor underneath it are made
of non-conductive materials.
This multimeter is fully calibrated and
tested. Under normal use, no further
adjustment should be necessary ex-
cept as noted in this Owner’s Manual.
If the multimeter requires repair, do
not try to adjust it yourself. Take it to
your local RadioShack store.

NOT USE THIS DEVICE IF YOU
ARE UNFAMILIAR WITH ELEC-
TRICAL CIRCUITS AND TEST-
ING PROCEDURES.
• NEVER TRY TO PROBE WITH
BOTH TEST LEADS AT THE
SAME TIME OR HOLD BOTH
TEST LEADS IN ONE HAND.
