subtract the readied contact resistance value from the reading value.
● For high resistance measurement(>10MΩ), it is normal taking several
seconds to obtain stable reading.
●
If The LCD display‘OL’symbol ,it is indicating open circuit for the
tested resistor or the resistance value of resistor is higher than the
maximum range of the meter.
5-6. Diode check
The diode check function used to check diode, transistor and other
semiconductor device.
In the diode testing, the meter sends a current through the
semiconductor junction, and then measure the voltage drop across the
junction. A good silicon junction will drop between 0.5V to 0.8V.
1. Set the rotary switch to the “‘Ω ” position, and then
press the ‘FUNC’
Push key to into diode check mode.
2. Insert the red test lead into the “INPUT” terminal and the black test
lead into the “COM“ terminal.
3. For forward voltage drop reading on any semiconductor component, place
the red test lead on the component anode and place the black test lead
on the component cathode.
The measured forward drop voltage will show on the LCD display.
4. Reverse the test lead and measure the voltage across the diode again.
● If diode is good, the display shows ‘OL’
。
- 17 -
● If diode is shorted, the display shows ‘0’(zero)in both direction.
● If display shows ‘OL’ in direction, the diode is open.
5-7. Continuity check
Set the rotary switch to the “‘Ω ” position.
1. Press the “FUNC” push button to switch into continuity check mode.
2. Insert the red test lead to the “INPUT” terminal, and then black test
lead to the “COM” terminal.
3. Connect the test lead across with the object being measured. If the
resistance of a circuit under test is less than 50Ω
，
the buzzer will
sound.
5-8. Capacitance measurement
Warning:
To avoid damage to the meter or to the equipment under test,
disconnect power and
discharge all high-voltage capacitors before measuring
capacitance.
You can use the DC voltage function to confirm that the capacitor
is discharged.
Capacitance ranges are 50.00nF, 500.0nF, 5.000uF, 50.00uF, 200.0uF.
To measure capacitance, connect the Meter as follows:
1. Set the rotary switch to“ ” position.
2. Insert the Capacitor under test to the “INPUT” terminal and “COM”
terminal.
The measured value will be displayed on the LCD disp
