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. 

 

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. 

 

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. 

 

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 30

Ω

, 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. 

 

Open the battery cover on the bottom case by 

screwdriver. 

 

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.
