Caution
To avoid damage to the Meter or to the equipment under test,
disconnect power and discharge all high-voltage capacitors
before measurement capacitance.
5-4 Diode Check
You can selecting the Scanning Mode or the Diode Mode by
The ‘FUNC’ push button.
① Use the diode test mode to check diodes, transistors and other
semiconductor device. In the diode test mode sends a current through
the semiconductor junction, and the measure the voltage drop across
the junction. A good silicon junction drop between 0.5V — 0.8V.
② For forward voltage drop reading on any semiconductor component,
the test pin(connected to the ‘INPUT’ terminal) is in touch with the
component anode and the another test pin is in touch with on the
component cathode. The measured value show on the LCD.
③ Reverse the test pin and measure the voltage across the diode again.
If diode is good, the display shows “OL”.
If diode is shorted, the display shows 0 (zero) in both direction.
If display shows “OL” in both direction, the diode is open.
5-5. Continuity Check
May selecting Scanning Mode or Continuity Mode by ’FUNC’ push
button.
When the resistance reading is less than 30Ω, the buzzer
generates 2KHz beep to indicate continuity.
6. Maintenance
6-1. Replacing The Battery
When meter display , the battery must be replace to maintain
normal operation.
① Open the battery cover on the bottom case by
screwdriver.
② Remove old battery and snap new one into battery
holder
Note:
Lithium Battery type: 3V CR2032
6-2. Cleaning
The meter can be cleaned with soft clean cloth to remove any oil, grease or
grim.
Do not use liquid solvent or detergent.
