MEASUREMENTS
WARNING:
Risk
of
electric
shock.
To
prevent
damage
to
the
meter
or
personal
injury,
never
measure
current
where
open
circuit
voltages
exceed
250V.
NOTE:
‘OL’
indicates
an
over
‐
range
condition
in
manual
mode.
A
higher
range
should
then
be
selected.
1.
Use
the
probe
cover
if
making
measurements
on
category
III
or
above
installations
2.
Set
the
function
dial
to
the
mA
position.
3.
Use
the
Mode
(M)
button
to
select
AC
or
DC
.
4.
Insert
the
black
test
lead
banana
plug
into
the
negative
jack
at
the
bottom
of
the
meter.
5.
Connect
the
test
leads
in
series
with
the
circuit
under
test.
6.
Touch
the
black
test
probe
tip
to
the
negative
side
of
the
circuit.
7.
Touch
the
positive
test
probe
tip
to
the
positive
side
of
the
circuit.
8.
Read
the
current
reading
on
the
display.
The
meter
automatically
selects
the
optimum
range
or
the
user
may
manually
select
a
range
by
pressing
the
Range
(R)
button.
Press
and
hold
the
Range
(R)
button
to
return
to

DIODE
TEST
NOTES:
The
display
shows
the
approximate
forward
voltage
drop.
If
the
connections
are
reversed
or
the
leads
are
not
connected,
the
display
will
show
‘OL’.
1.
Use
the
probe
cover
if
making
measurements
on
category
III
or
above
installations
2.
Set
the
function
switch
to
the
position.
3.
Use
the
Mode
(M)
button
to
select
the
diode
function
4.
Insert
the
black
test
lead
banana
plug
into
the
negative
(common)
jack
at
the
bottom
of
the
meter.
5.
Touch
the
test
probes
to
the
diode
under
test.
6.
A
good
diode
will
indicate
approx.
0.3V
(germanium
diodes)
to
0.7V
(silicon
diodes)
for
the
forward
test
and
“
OL
”
for
the
reverse
test.
7.
A
shorted
diode
will
indicate
the
same
value
of
voltage
in
both
the
reverse
and
forward
test
directions.
An
open
diode
will
indicate
“
OL
”
in
both
test
directions.
