Precautions
Read and
follow
these safety precautions.
• 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
working
with voltages above
1
OOV.
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

A.
• Always discharge any capacitors
of
the
circuit
under
test
before
you attach
test
leads.
• Always turn
off
power
and
disconnect
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.
• Never try
to
probe
with
both
test
leads
at
the
same
time
or
hold
both
test
leads in
one
hand.
• The
test
leads
supplied
with your
meter
are rated
for
1000 volts. Use only
test
leads
of
the
same rating with
the
meter.
You
can
order
replacement leads
from
your local
RadioShack
store.
•
Do
not
use a fuse
brand
or
rating
other
than those specified here.
Doing
so
might
damage
your
meter
.
• 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.
• Your
multimeter
is
designed
primarily
to
measure
household
AC
voltages.
Because
of
the
dangers inherent in measuring
three
-phase circuits, WE
STRONGLY
RECOMMEND
YOU
DO
NOT
USE
THIS METER
TO
MEASURE
3-PHASE, LINE-TO-LINE VOLTAGE. If you still
want
to,
put
on
protective
clothing-a
face shield and
fireproof
gloves and
upper
body
protection
is
required
before
measuring. If you
do
not
have this
protection,
DO
NOT
MEASURE THESE CIRCUITS.
•
To
reduce
the
risk
of
fire
or
shock hazard,
do
not
expose this
product
to
rain
or
moisture. For
indoor
use only.
•
When
you are
not
using
the
meter, always turn
it
off
.
• If this
equipment
is
used in a manner
not
specified in this user's
guide,
the
protection
provided
by
the
equipment
may
be
impaired
