Operating instruction
Measuring Current
1. Connect the black test lead to the COM
jack. If the current to be measured is less
than 400mA, connect the red test lead to
the µAmA°C°F jack. If the current is between
400 mA and 10 A, connect the red test lead
to the „10 A" jack instead.
2. Set the range switch to desired „
or„ " range.
3. Select ac current or dc current measure-
ment with the „FUNC„ button, the display
shows the relevant symbol (
4. Turn off power to the circuit which you
want to measured. Discharge all capacitors.
5. Break the circuit path to be measured, con-
nect the test leads in series with the circuit.
6. Turn on power to the circuit, then read the
display. For dc current measurement, the po-
larity of the red test lead connection will be
indicated as well.
Note:
If you don't know the magnitude of the cur-
rent to be measured beforehand, select the
highest range and then reduce it range by
range until satisfactory resolution is obtai-
ned.
Measuring Resistance
1. Connect the black test lead to the COM
jack, and the red test lead to the
jack. ( Note: The polarity of the red lead is
positive „ + „. )
2. Set the range switch to Ω range, „ Ω" ap-
pears on the display.
3. Connect the test leads across the load to
be measured.
4. Read the reading on the display.

Note:
1. For resistance above 1MΩ, the meter may
take a few seconds to stabilize reading. This
is normal for high resistance measurements.
2. When the input is not connected, i.e. at
open circuit, „OL " will be displayed as over-
range indication.
" , 3. Before measuring in-circuit resistance,
make sure that the circuit under test has all
power removed and all capacitors are fully
discharged.
bzw. ).
Continuity Test
1. Connect the black test lead to the COM
jack, and the red test lead to the
jack. (Note: The polarity of the red lead is po-
sitive „ + „. )
2. Set the range switch to
the FUNC button until the symbol
pears on the display.
Note:
Before performing in-circuit continuity test,
make sure that the circuit under test has all
power removed and all capacitors are fully
discharged.
Diode
1. Connect the black test lead to the COM
jack, and the red test lead to the
jack. (Note: The polarity of the red lead is po-
sitive „ + „.)
Set the range switch to
FUNC button until the symbol
the display.
3. Connect the red test lead to the anode of
the diode to be tested, and the black test lead
to the cathode.
