Product selling points and features: 1. The output voltage is 110-2600V DC. You can turn the voltage adjustment button clockwise to increase the voltage and counterclockwise to decrease the voltage.The output current is 0.25~3.4mAh. You can turn the voltage adjustment button clockwise to increase the current and counterclockwise to decrease the current.<br> 2. Widely used: This tool can be widely used for MOS, transistor, IGBT, diode, Zener diode, diode bridge maximum voltage capacity testing, voltage verification of capacitors and varistors, LED backlight and lamp board testing, etc<br> 3. When testing MOS transistors, transistors, and Zener diodes, it is recommended to adjust the current to the minimum scale of 0.25mA. When testing the LED backlight board, it is recommended to adjust the current to the maximum scale of 3.4mAh.<br> 4. Portable size: The small size of this tool is very convenient for daily use. You can carry it in a tool bag without occupying too much storage space.<br> 5. Equipped with a built-in 660mAh high capacity lithium battery for power supply, it can be in a timely manner through the Type-C interface.<br> Product parameters:<br> Battery capacity: 3.7V 600mAH<br> Charging port: TYPE-C<br> Input: 5V 1A<br> Charging current: Max.550mA<br> Output voltage: 120-2700V<br> Output current: 0.2-3.8mA<br> Applicable components: MOS tube/IGBT/triode/diode/Electrolytic capacitor/LED/MOV/unidirectional thyristor/rectifier bridge<br> Test objective: Breakdown voltage value of electronic components<br> Power supply: built-in lithium battery 500mah<br> Attention:<br> 1. Do not use it to test 450V/220UF and other high-voltage large Electrolytic capacitor. It is possible to test low-voltage capacitors such as 2200UF/35V.<br> 2. If there is no output voltage when pressing the red high-voltage start button, it is likely that the lithium battery voltage is lower than 3.1V and the tester ot be powered on. It needs to be in a timely manner.<br> 3. Only when testing and voltage regulator diodes can the output current be adjusted to the maximum value. For testing other components, the output current can be adjusted to the minimum value to avoid damaging the components<br> Standard: Blue<br> Material: plastic<br> colour: As Shown<br> Package Contents:<br> 1 x Transistor Tester<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.<br> Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Minnanxin
