A Word About Safety - Radio Shack 22-812 Owner's Manual

A WORD ABOUT SAFETY

We have taken every precaution in
designing this meter to ensure that it
is as safe as we can make it. But safe
operation depends on you, the opera-
tor. We recommend that you follow
these simple safety rules:
• Never apply voltages to the
meter that exceed the limits
given in the specifications. Never
apply more than 1000V DC or
750V RMS AC between the input
jacks and ground.
• Use extreme caution when work-
ing with voltages above 100V.
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
voltage source when you set the
meter's function selector 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 meter's battery or
fuse.
• Never operate the meter unless
its back cover and battery cover
are in place and fully closed.

• 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 meter is fully calibrated and test-
ed. Under normal use, no further ad-
justment should be necessary except
as noted in this Owner's Manual. If
the meter requires repair, do not try to
adjust it yourself. Take it to your local
RadioShack store.
