test
leads look
damaged.
•
Always
turn
off
power
to
the
circuit
before
cutting, unsoldering, or breaking the
circuit.
Small
amounts
of
current
can be
dangerous.
•
Never measure
resistance
in
a
circuit
when
power
is
applied
to
the
circuit.
•
Never
touch the probes
to
a
voltage source
when
the
test
leads are plugged
into
the
10A
or
300
mA
input jack.
•
To
avoid
damage
or
injury,
never use
the
meter
on
unprotected
circuits that
exceed 4800
volt-amps.
•
Never
apply
more
than
1000V
dc
or
750V
ac
rms
(sine)
between any
input jack
and
earth
ground.
•
Always be
careful
when
working
with
voltages
above
60V
dc
or
30V
ac
rms.
Such
voltages
pose a shock
hazard.

the
finger
guards on
the probe
when
making
measurements.
•
Always use a
