the
protection
provided
by
the
Meter
might
be
impaired.
«
Avoid
working
alone
so
assistance
can
be
rendered.
+
Never
measure
AC
current
while
the
test
leads
are
inserted
into
the
input
jacks.
«
Do
not
use
the
Meter
in
wet
or
dirty
environments.
«
Inspect
the
test
leads
before
use.
Do
not
use
them
if
insulation
is
damaged
or
metal
is
exposed.
+
Check
the
test
leads
for
continuity.
Replace
damaged
test
leads
before
using.
«
Use
extreme
caution
when
working
around
bare
conductors
or
bus
bars.
Contact
with
the
conductor
could
result
in
electric
shock.
1
+
Do
not
hold
the
Meter
anywhere
beyond
the
tactile
barrier.
«
Do
not
apply
more
than
the
rated
voltage,
as
marked
on
the
Meter,
between
the
terminals
or
between
any
terminal
and
earth
ground.
+
Remove
test
leads
from
the
Meter
before
opening
the
Meter
case.
«
Never
operate
the
Meter
with
the
back
cover
removed
or
the
case
open.
«
Never
remove
the
back
cover
or
open
the
case
of
an
instrument
without
first
removing
the
test
leads
or
the
jaws
from
a
live
conductor.
«
Use
caution
when
working
with
voltages
above
30
V
ac
RMS,
42
V
ac
peak,
or
60
V
dc.
These
voltages
pose
a
shock
hazard.
«
Do
not
attempt
to
measure
any
voltage
that
might
exceed
the
maximum
range
of
the
Meter-
1000
V
RMS.
«
Do
not
operate
the
Meter
around
explosive
gas,
vapor,
or
dust.
«
When
using
probes,
keep
fingers
behind
the
finger
guards.
+When
making
electrical
connections,
connect
the
common
test
lead
before
connecting
the
live
test
lead;
when
disconnecting,
disconnect
the
live
test
lead
before
disconnecting
the
common
test
lead.
«
Disconnect
circuit
power
and
discharge
all
high-voltage
capacitors
before
testing
resistance,continuity,
or
diodes.
«
Check
the
operation
of
the
meter
at
a
known
source
before
and
after
use.
