CAUTION:
Remove
test
leads
from
meter
before
attempting
NCV
tests.
Always
verify
the
NCV
function
on
a
known
live
circuit
before
performing
tests.
Do
not
use
the
NCV
function
if
the
display
does
not
show
EF
when
the
function
switch
is
turned
to
the
NCV
position.
If
the

when
the
NCV
mode
is
initiated,
please
check
the
batteries.
With
the
meter
on
and
switched
to
the
NCV
mode,
holding
the
front
tip
of
the
clamp
jaw
near
a
live
electrical,
electromagnetic,
or
electrostatic
field
causes
the
beeper
to
sound,
the
display
to
shows
dashes,
and
the
red
LED
lamp
to
flash.
The
threshold
is
100V.
The
greater
the
field
strength
the
greater
the
number
of
dashes
and
the
faster
the
rate
of
the
audible
beeps
and
the
flashing
LED
lamp.
If
the
meter
does
not
emit
a
tone
or
display
dashes
in
this
mode,
there
is
still
the
possibility
that
voltage
is
present.
Please
use
caution.

3.
Place
the
meter
near
a
source
of
electrical

when
an
electrical
or
electromagnetic

detector,
this
is
normal.
