DIY IGBT Voltage Capability Diode Triode MOV MOS Testing LED Back-light Repair With LED Display Screen Release -Blue LED

Dear customers, since July 15th, we have upgrade the product with adding polarity exchange terminal, orders since July 15th on wards will sh new version, pls. note. Since July 22nd Beijing time, face and back side stickers will be added onto product and sh.

Specification:

Name: DIY Transistor Voltage Capacity .

Output Voltage: DC 100~2600V, turn voltage adjust on clockwise bigger, Counterclockwise smaller.

Output Current: 0.25~3.4mA, turn current adjust on clockwise bigger, Counterclockwise smaller. Suggest use 0.25mA to test electronic component's voltage, use 3.4mA to do LED back light's repair testing.

Product net weight: 105 g include testing line.(not include lithium battery)

Application:

Testing MOS/Triode/IGBT/Diode/Zener diodes/Diode Bridge Max. Voltage Capacity to avoid electronics bought are not comply with spec. and cause malfunction.

and Varistors' voltage verification

LED backlight and light board testing and identify fail led bead.

Power supply: 3.7V 660mAH 443441 lithium battery(battery not included in package) or DC 5V 1A mobile phone power supply

Charge port: TYPE-C

Charging current for the lithium battery: 500mA

Charging LED indicator: Charging with red light on, charging over with red light off.

Usage guide:

Power on ：Switch on and 8888 led tube show 0000 means is power on.

Set proper output voltage : pre red high voltage start on,no cl to any electronic component,8888 LED

tube shows current output voltage value. For example, testing 1N4007 diode, Spec.1000V re withstand preure，then output voltage must set to 1.4 times of 1000V, one hand pre the high voltage start on, the other hand clockwise adjust the voltage on to above 1400V.

Set proper output current : for MOS tube/IGBT/ Triode /Diode，set output current at 0.25mA（the Min. output current will be ok）；Testing LED back light, Regulated diodes，set output current at 3.4mA（the Max. output current will be ok）

Testing and read the voltage value ：use red and black cl catch two poles of 1N4007,after ensure polarity is right, pre red high voltage start on, if the voltage value shows on LED screen is lower than set value, it means the 1N4007 is breakdown.If the voltage value shows on LED screen is same as set value, it means set output voltage is not high enough, need set bigger output voltage value.

After use : pls. adjust the voltage and current on to the Min. position and turn off the power.

Below is general electronic components testing polarity reference.

Pls. note:

Don’t use it to test high voltage big electrolytic s like 450V/220UF etc. it is ok to test low voltage s like2200UF/35V.

If there is no output voltage when pre down the red high voltage start on, it is likely the lithium battery voltage is

lower than 3.1V and can’t power on the , need charge in time.

Only when testing LED , the output current can be adjusted to the Max. value, for testing other components,the output current can be adjusted to the Min. value to avoid damage the components.

Package:

1pcs DIY Transistor Voltage Capacity (3.7V 660mAH lithium battery not included)&1pcs testing cable with two black and one red cl.

below is new version with polarity exchange terminal since July 15th on wards.
