auto-
ranging
digital
multimeter.
Safety
Information
To
avoid
possible
electrical
shock,
fire,
or
personal
injury,
please
read
all
safety
information
before
you
use
the
product.
Please
use
the
product
only
as_
specified,
or
the
protection
supplied
by
the
product
can
be
compromised.
*
Examine
the
case
before
you
use
the
product.
Look
for
cracks
or
missing
plastic.
Carefully
look
at
the
insulation
around
the
terminals.
*
The
measurement
must
be
made
with
correct
input
terminals
and
functions
and
within
the
allowable
measuring
range.
*
Do
not
use
the
product
around
explosive
gas,
vapor,
or
in
damp
or
wet
environments.
Keep
fingers
behind
the
finger
guards
on the
probes.
When
the
product
has
already
been
connected
to
the
line
being
measured,
do
NOT
touch
the
input
terminal
that
is
not
in
service.
Disconnect
the
test
leads
from
the
circuit
before
changing
the
mode.
When
the
voltage
to
be
measured
exceeds
36V
DC
or
25V
AC,
the
operator
shall
be
careful
enough
to
avoid
electric
shock.
Misuse
of
mode
or
range
can
lead
to
hazards,
be
cautious.
