RESISTANCE
MEASUREMENTS
WARNING:
To
avoid
electric
shock,
disconnect
power
to
the
unit
under
test
and
discharge
all
capacitors
before
taking
resistance
measurements.
Remove
batteries
and
unplug
line
cords.
1.
Set
the
function
switch
to
the
Ω
position.
2.
Insert
the
black
test
lead
banana
plug
into
the
negative
COM
jack.
Insert
the
red
test
lead
banana
plug
into
the
positive
Ω
jack.
3.
Press
the
SELECT
button
to
indicate
Ω
on
the
display.
4.
Touch
the
test
probe
tips
across
the
circuit
or
part
under
test.
It
is
best
to
disconnect
one
side
of
the
part
under
test
so
the
rest
of
the
circuit
will
not
interfere
with
the
resistance
reading.
5.
Read
the
resistance
in
the
display.
Resistance
Measurement
Notes
The
display
shows
OL
when
the
measured
resistance
open
‐
circuit
or
resistance
value
exceeds
maximum
range.
When
measuring
low
resistance,
a
test
‐
lead
measurement
error
of
0.1
to
0.2
will
exist.
Short
the
test
leads
and
use
the
Relative
mode
to
null
the
test
‐
lead
error.
Check
the
test
leads
for
loosening
or
other
breakage
and
verify
that
the
lead
resistance
is
0.5
or
less
by
shorting
the
leads
and
viewing
the
displayed
reading.
Replace
test
leads
if
necessary.
Several
seconds
are
required
for
stability
when
taking
high
resistance
measurements.
Do
not
input
signals
>
60VDC
or
30VAC.
CONTINUITY
CHECK
WARNING:
To
avoid
electric
shock,
never
measure
continuity
on
circuits
or
wires
that
have
voltage
on
them.
1.
Set
the
function
switch
to
the
Ω
position.
2.
Insert
the
black
lead
banana
plug
into
the
negative
COM
jack.
Insert
the
red
test
lead
banana
plug
into
the
positive
Ω
jack.
3.
Press
the
SELECT
button
to
indicate
Ω
on
the
display
4.
Touch
the
test
probe
tips
to
the
circuit
or
wire
you
wish
to
check.
5.
If
the
resistance
is
>
150
Ω
there
will
be
a
break
in
the
circuit
but
no
beeper
will
sound.
If
the
resistance
is
≤
10
Ω
,
the
beeper
signal
will
sound.
If
the
circuit
is
open,
the
display
will
indicate
“OL”.
