3. Before measuring in-circuit resistance, be sure that the circuit under test has all power removed and all
capacitors are fully discharged.
Measuring Capacitance
1. Connect the black test lead to the „COM" jack and the red test lead to the „INPUT" jack.
2. Set the range switch to desired „1000μF", " 20μF" or „nF" position.
3. Select auto range or manual range with the „RANGE" button.
4. Connect test leads across the capacitor to be measured. Make sure that the polarity of connection is
observed ( The red test lead should be connected to the anode of the capacitor, the black one should be
connected to the cathode of the capacitor ).
5. Read the reading on the display.
Note:
In small range, before the test leads are connected to the capacitor, the display may show a reading, it is
normal because of the stray capacitance of the test leads and input circuit of the meter. It will not affect the
measurement accuracy.
Continuity 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 „+" ).
2. Set the range switch to range
3. Press the „FUNC. " button to select continuity measurement mode, and the symbol
indicator.
4. Connect the test leads to the circuit to be measured.
5. If the circuit resistance is lower than about 30 , the built-in buzzer will sound.
Diode
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 „+" ).
2. Set the range switch to range
3. Press the „FUNC. " button to select diode measurement mode, and the symbol
indicator.
4. Connect the red test lead to the anode of the diode to be tested and the black test lead to the cathode.
5. The meter will show the approximate forward voltage of the diode.
6. If the connections are reversed, „OL" will be shown on the display.
Transistor Test
1. Set the range switch to hFE position.
2. Connect the adapter to the „COM" jack and the „INPUT" jack. Don't reverse the connection.
3. Identify whether the transistor is NPN or PNP type and locate emitter, base and collector lead. Insert the
leads of the transistor to be tested into the proper holes of the transistor test socket of the adapter .
4. LCD display will show the approximate hFE value.
Measuring Temperature
1. Set the range switch to Temp range.
2. Press the „FUNC. " button to select °C or °F mode, and the symbol „ °C „ or „ °F „ will appear as an indicator.
