Resistance
Measurements
CAUTION
:
Switch
OFF
power
to
the
device
under
test
before
measuring.
Do
not
test
on
circuits
or
devices
where
60VDC
or
30VAC
is
present.
1.
Insert
the
black
test
lead
banana
plug
into
the
negative
(COM)
jack.
Insert
the
red
test
lead
banana
plug
into
the
positive
(V/
Ω
)
jack.
2.
Turn
the
Function
Switch
to
the
Ω
position.
3.
Use
the
M
button
to
select
the
Ω
icon
on
the
display
indicating
resistance
only
(without
the
continuity/diode/capacitance
icons
showing).
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
value
in
the
display.
The
display
will
indicate
the
proper
decimal
point
and
value.
If
the
reading
is
out
of
range,
the
OL
display
icon
will
appear.

Measurement
Notes:
The
display
will
show
“OL”
when
an
open
circuit
is
detected
or
if
the
resistance
>
maximum
range.
The
test
leads
introduce
an
error
of
approx.
0.1
Ω
～
0.2
Ω
for
low
resistance
measurements.
Use
the
Relative
mode
to
obtain
accurate
readings.
Short
the
test
leads
together,
press
the
REL
button,
and
then
measure
a
low
resistance.
The
meter
subtracts
the
short
‐
circuit
value
from
the
reading.
If
the
test
lead
resistance
of
probe
is
>
0.5
Ω
when
shorted,
inspect
the
test
leads
and
the
connection.
It
may
take
several
seconds
for
the
reading
to
stabilize
when
measuring
resistance
>1M
Ω
.
This
is
normal
operation.
For
personal
safety,
do
not
measure
a
circuit
with
voltages
>
30V
DC
or
AC.
