7. Read the reading on the display. For DC current measurements, the polarity of the positive ( + ) output lead of the clamp will
be indicated as well.
Note:
1. ln manual range mode, when the display shows the overrange indicator "OL", a higher range should to be selected.
2. Don’t touch the circuit under test with hand or skin.
3. Matching problem about the meter and the sensitivity of the clamp:
a. The sensitivity of the matching damp is 0.1A/0.1mV. lf you use a matching clamp, the present indicated value is same
to the measured value.
b. If you use a clamp whose sensitivity does not equal 0.1A/0.1 mV, you should multiply the present reading by a factor
which is determined by the used clamp, the result is the measured value.
To determine the factor, please refer to the instruction of the clamp which you use.
Measuring Resistance
1. Connect the black test lead to the "COM" jack and the red test lead to the "INPUTʺ jack.
2. Set the range switch to
Ω
range.
3. Select auto range or manual range mode wilh the ʺRANGEʺ button.
4. Connect the test leads across the load to be measured. Read the reading on the display.
Note:
1. For resistance measurements > 1 MΩ, 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, the symbol "OL" will be displayed as an overrange indicator.
3. Before measuring in-circuit resistance, be sure that the circuit under test has all power removed and all capacitors have
been fully discharged.
4. ln manual range mode, when the display shows the overrange indicator "OLʺ, a higher range has to be selected.
Measuring Capacitance
1. Connect the black test lead to the "COMʺ jack and the red test lead to lhe "INPUTʺ jack.
2. Set the range switch to desired
"1000µF"
,
"20µFʺ
or
"nFʺ
position.
3. Select autorange or manual range mode wilh the "RANGEʺ button.
4. Connect test leads across the capacitor to be measured. Make sure that the polarity of the capacitor is observed.
(The red test lead should be connected to the anode of the capacitor, and the black one should be connected to the
cathode of the capacitor.)
5. Read the reading on the display.
Note:
ln small range, before the test leads are connected to the capacitor, the display may show a reading. This is normal because
of the stray capacitance of the test leads and input circuit of the meter and will not affect the measurement accuracy.
Continuity Test
1. Connect the black test lead to the "COMʺ jack and the red test lead to the "INPUTʺ jack.
2. Set the range switch to
range.
3. Press the
"FUNC."
button until the symbolʺ
ʺappears on the display.
4. Connect the test leads across the circuit to be measured.
5. If the resistance is lower than about 30Ω, the built-in buzzer will sound.
Note:
Before test, disconnect all power to the circuit to be tested and discharged all capacitors fully.
Diode Test
1. Connect the black test lead to the "COM" jack and the red test lead to the "INPUT" jack (Note: The polarity of the red test
lead is positive "+ʺ ).
2. Set the range switch to
range.
3. Press the
"FUNC.ʺ
button until the symbol ʺ
ʺ appears on the display.
4. Connect the red test lead to the anode of the diode to be tested and the black test lead to the cathode of the diode.
5. The display will show the approximate forward voltage drop of the diode. If the connections are reversed, "OL" will be
shown on the display.
Transistor Test
1. Set the range switch to
h
FE
position.
2. Refer to the Figure 2, connect the adapter to the "COM" jack and the "INPUT" jack. Don’t reverse the connection.
3. ldentify whether the transistor is NPN or PNP type and locale emitter, base and collector leads. lnsert the leads of the
transistor to be tested into the proper holes of the transistor test socket of the adapter.
4. The display will show the approximate
h
FE
value.
