Continuity
Test
Warning:
Do
not
do
diode,
resistance
or
continuity
tests
before
removing
the
power
from
capacitors
and
other
devices
under
test
during
a
measurement.
Injury
to
persons
can
occur.
1.
Set
the
function
switch
to
the
position.
2.
Use
the
button
to
select
continuity
measurement.
The
indicator
will
be
displayed.
3.
Insert
the
black
probe
lead
into
the
negative
COM
terminal
and
the
red
probe
lead
into
the
positive
terminal.
4.
Touch
the
tips
of
the
probe
across
the
circuit
or
component
under
test.
5.
If
the
resistance
is
30
±
5
Ω
(nominal)
or
less,
the
meter
beeps.
Note:
This
threshold
is
user
selectable
in
the
SET
UP
menu
under
the
Cntin
(continuity)
setting:
Range:
10
‐
50
Ω
;
Increment:
1;
Default:
30
Ω
.
5.7
Diode
Test
Warning:
Do
not
do
diode,
resistance
or
continuity
tests
before
you
have
removed
the
power
from
capacitors
and
other
devices
under
test
during
a
measurement.
Injury
to
persons
can
occur.
1.
Set
the
function
switch
to
the
position.
2.
Use
the
button
to
select
the
diode
test
function.
The
indicator
will
be
displayed.
3.
Insert
the
black
probe
lead
into
the
negative
COM
terminal
and
the
red
probe
lead
into
the
positive
terminal.
4.
Touch
the
tips
of
the
probe
across
the
diode
or
semiconductor
junction
under
test.
Make
a
note
of
the
value
on
the
display.
5.
Reverse
the
polarity
of
the
probes,
by
interchanging
the
probe
test
locations.
6.
Touch
the
tips
of
the
probe
across
the
diode
or
semiconductor
junction
under
test.
Make
a
note
of
the
new
value
on
the
display
7.
The
diode
or
semiconductor
junction
can
be
evaluated
as
follows:
If
one
of
the
readings
displays
a
value
(typically
0.400
V
or
0.900
V)
and
the
other
reading
displays
OL
,
the
component
is
good.
If
both
readings
display
OL
,
the
component
is
open.
If
both
readings
are
very
small
or
0,
the
component
is
shorted.
5.8
Capacitance
Measurements
Warning:
Do
not
do
capacitance
tests
before
removing
the
power
to
the
capacitor
or
other
devices
under
test
during
a
measurement.
Injury
to
persons
can
occur.
1.
Set
the
function
switch
to
the
position.
2.
Use
the
button
to
select
the
capacitance
measurement.
The
F
(Farad)
unit
will
be
displayed.
3.
Insert
the
black
probe
lead
into
the
negative
COM
terminal
and
the
red
probe
lead
into
the
positive
terminal.
4.
Touch
the
tips
of
the
probe
across
the
part
under
test.
