AC/DC Voltage Measurements
Warnings
Observe all safety precautions when working on live
voltages.
1
.
Put the
function
select switch to
audible.
2
.
Touch the test probes across the circuit being
measured.
3.The tester will turn on automatically if the voltage
exceeds 12 volts.
4.The LEDs will indicate the voltage.
5.For AC voltage, the “+” and “-” LEDs will illuminate.
6.For DC voltage, the “+” LED will illuminate if the
instrument test probe is touching the positive side
of the circuit. The “-” LED will illuminate if the
instrument test probe is touching the negative
side of the circuit.
7.The buzzer will ring
when
the
Voltage
is
higher
than
about
50 volts.

Maintenance
1.keep the tester dry. if it gets wet, wipe it off.
2.use and store the tester in normal temperatures.
temperature extremes can shorten the life of the
electronic parts and distort or melt plastic parts.
3.handle the tester gently and carefully. dropping
it can damage the electronic parts or the case.
4.keep the tester clean. wipe the case occasionally
with a damp cloth. do not use chemicals, cleaning
solvents, or detergents.

Test
Warnings
Observe all safety precautions when working on live
voltages.
The
GFCI
test
function
can
only
be
used
on
120
volt
AC
receptacles
with
GFCI
protection
.
1
.
Check
the
instructions
on
the
specific
GFCI
device
you
are
testing
before
proceeding.
2
.
Put the
function
select switch to
GFCI
test.
3
.
Press
the
test
button
on
the
GFCI
receptacle
.
The
GFCI
should
trip
.
If
not
,
do
not
use
the
receptacle
and
consult
a
qualified
electrician
.
If
it
does
trip
,
press
the
reset
button
on
the
GFCI
receptacle
.
4.Insert
one
test
probe
into
hot
side
of
the
outlet
being
tested
.
5
.
Insert
the
other
test
probe
into
the
ground
of
the
outlet
being
tested
.
6
.
The
tester
should
indicate
120VAC
if
the
outlet
is
powered
and
wired
properly
.
7
.
Press
the
GFCI
test
button
.
8
.
The
indicator
lights
should
turn
off
indicating
the
GFCI
has
tripped
.
9
.
If
the
GFCI
does
not
trip,either
the
receptacle
is
mis-wired
or
the
GFCI
is
defective.Do
not
use
the
receptacle
and
consult
a
qualified
electrician
.
