ʻ
AC
ʼ and ʻ
V
ʼ appear on the display and the LED
next to V/ / / jack turns on.
➔
Plug the red test lead in V/ / / jack and
black test lead in
jack.
➔
Apply the test leads to the circuit to
be measured.
➔
Read the displayed TRMS voltage.
➔
If ʻOLʼ appears on the display, it
indicates over-range. Immediately
remove test leads from the measur-
ing circuit to avoid any damage to
the meter. The input voltage should
not exceed the measurement capa-
bility of this meter.
3. DC CURRENT MEASUREMENT
WARNING
: WHEN MEASURING CURRENT REMOVE ALL POWER FROM THE CIRCUIT
BEING TESTED. NEVER APPLY THE TEST LEAD TO THE MEASURING CIRCUIT WHEN CHANG-
ING THE POSITION OF THE FUNCTION SWITCH.
NOTE: The meter will be Auto ranging for this function. If you wish to measure with
Manual range, follow instructions described in Section 9. For manual ranging, start at
the highest range and work down.
a) Less than 326mA DC Current Measurement
➔
Set the function switch to
mA

ʻ
mA
ʼ appears on the display and the LED next to
µA/mA jack turns on.
➔
Plug the red test lead in µA/mA
jack and black test lead in the
jack.
➔
Remove power from the circuit that
is to be measured. Open up the
circuit and connect the black lead to
the negative side and the red lead
to the positive side of the circuit so
that the test leads are in series with
the load to be measured.
