MEASUREMENTS
CAUTIONS:
Do
not
make
5A
current
measurements
for
longer
than
10
seconds.
Allow
15
minutes
between
tests.
Exceeding
10
seconds
may
cause
damage
to
the
meter
and/or
the
test
leads.
Before
connecting
the
meter
in
a
series
circuit
turn
off
the
power
supply
to
the
series
loop.
Start
with
the
highest
range
possible
if
unsure
of
expected
current
measurement.
Fuses
are
provided
in
the
10A
and
µA/mA
input
jacks.
Do
not
connect
test
leads
in
parallel
to
any
circuit
when
test
leads
are
connected
to
these
jacks.
Pressing
the
HZ
‐
%
button,
while
taking
AC
current
measurements,
is
allowed.
1.
Insert
the
black
test
lead

jack.
2.
For
current
measurements
up
to
6000µA
AC,
set
the
function
switch
to
the
µA
position
and
insert
the
red
test
lead
banana
plug
into
the
µA/mA
jack.
3.
For
current
measurements
up
to
600mA
AC,
set
the
function
switch
to
the
mA
position
and
insert
the
red
test
lead
banana
plug
into
the
µA/mA
jack.
4.
For
current
measurements
up
to
10A
AC,
set
the
function
switch
to
the
A
position
and
insert
the
red
test
lead
banana
plug
into
the
10A
jack.
5.
Press
the
SELECT
button
to
indicate
“AC”
on
the
display.
6.
Remove
power
from
the
circuit
under
test,
then
open
up
the
circuit
at
the
point
where
you
wish
to
measure
current.
7.
Touch
the
black
test
probe
tip
to
the
neutral
side
of
the
circuit.
Touch
the
red
test
probe
tip
to
the
“hot”
side
of
the
circuit.
8.
Apply
power
to
the
circuit.
9.
Read
the
current
in
the
display.
10.
Press
the
Hz/%
button
to
indicate
“Hz”.
11.
Read
the
