Preparing for Current Measurements
x
Turn off circuit power before connecting the test probes.
x
Allow the meter to cool between measurements if current measurements
approach or exceeds 10 amps.
x
A warning tone sounds if you connect a test lead to a current input before you
select a current function.
x
Open circuit voltage at the measurement point must not exceed 1000 V.
x
Always measure current in series with the load. Never measure current across a
voltage source.
Measuring DC Current
See Figure
-4-
1.
Set the Function Switch to a current function,
µA
,
mA
, or
10A
.
2.
If the
10A
function is not selected and
RANGE
is displayed, press the
RANGE
button to enable autoranging.
3.
Connect the Test Leads: Red to
µA mA
or
10A
, Black to
COM
4.
Turn off power to the circuit being measured.
5.
Open the test circuit (
(
) to establish measurement points.
6.
Connect the Test Probes in series with the load.
7.
Turn on power to the circuit being measured.
8.
Read the display, and, if necessary, correct any overload (
-
or
-
) conditions.
Measuring AC Current (True rms) See Figure
-3- & -5-
See
Additional Features
to find out the advantages of true rms.
1.
Set the Function Switch to a current function and range,
µA
,
mA
, or
10A
.
2.
If
DC
is displayed, press the yellow button to turn on
AC
.
3.
If the
µA
or
mA
function is not selected and
RANGE
is displayed, press the
RANGE
button to enable autoranging.
4.
Connect the Test Leads: Red to
µA mA
or
10A
, Black to
COM
5.
Turn off power to the circuit being measured.
