Set the range switch to range 2. Ω .
Select auto range or manual range with the „ 3.
RANGE
” button. In manual range mode, when the display
shows the overrange symbol „OL”, a higher range has to be selected.
Connect the test leads across the load to be measured. 4.
Read the reading on the display. 5.
Note:
For resistance measurements > 1MΩ , the meter may take a few seconds to stabilize reading. This is normal 1.
for high-resistance measurement.
When the input is not connected, i.e. at open circuit, the symbol „OL” will be displayed as an overrange 2.
indicator.
Before measuring in-circuit resistance, be sure that the circuit under test has all power removed and all 3.
capacitors are fully discharged.
Measuring Capacitance
Connect the black test lead to the „ 1. COM ” jack and the red test lead to the „ INPUT ” jack.
Set the range switch to desired „ 2. 1000μF ”,” 20μF ” or „ nF ” position.
Select auto range or manual range with the „ 3.
RANGE
” button.
Connect test leads across the capacitor to be measured. Make sure that the polarity of connection is 4.
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 ).
Read the reading on the display. 5.
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
Connect the black test lead to the „ 1. COM ” jack and the red test lead to the „ INPUT ” jack (Note: The polarity of
the red test lead is positive „+” ).
Set the range switch to range
2. .
Press the „ 3.
FUNC
.” button to select continuity measurement mode, and the symbol „ will appear as an
indicator.
Connect the test leads to the circuit to be measured. 4.
If the circuit resistance is lower than about 30 , the built-in buzzer will sound. 5.
Diode
Connect the black test lead to the „ 1. COM ” jack and the red test lead to the „ INPUT ” jack (Note: The polarity of
the red test lead is positive „+” ).
Set the range switch to range
2. .
Press the „ 3. FUNC .” button to select diode measurement mode, and the symbol will appear as an
indicator.
Connect the red test lead to the anode of the diode to be tested and the black test lead to the cathode. 4.
The meter will show the approximate forward voltage of the diode. 5.
If the connections are reversed, „OL” will be shown on the display. 6.
