2024 Transistor Tester Functions than the previous version, increased the shutdown time countdown display KAA zone needs to be opened manually, which reduces the damage of the instrument. Optimize some parameters. Built-in 300MAH 4.2V lithium battery, rechargeable. TFT 1.8-inch color screen display, graphical display of various parameters Automatically detects NPN and PNP transistors, N-channel and P-channel MOSFETs, IGBTs, diodes (including double diodes), thyristors, transistors, resistors and capacitors. Automatically detects the pinouts of components and graphically displays them on a color screen. Can detect infrared code (support format infrared remote control) Transistors, MOSFET protection diodes, etc. can be detected amplification coefficient and the base of the determination of the forward bias voltage of the emitter transistor Depletion type and enhancement type MOSFETs can be distinguished. MOSFETs with gate threshold voltage and gate capacitance can be measured. Supports measurement and symbol display of two resistors with a resolution of 0.1 Ohm and a maximum measurement value of 50M Ohm. and can be displayed for capacitors higher than 10UF. Measures inductance for resistances below 2100 ohms and DC resistance for inductances below 10UH. Higher test speed, expiration date component test: in 2 seconds (except in the larger capacitors, large capacitance measurement also need a longer time) Equipped with a calibration needle, calibrated to test small resistors more accurately One button operation, power on test Power consumption off mode: less than 20 nA Automatic shutdown function, saving battery energy, improve the duration. Color: As Shown Material: ABS Package Contents: 1 * tester 1 set * accessories Only the above package content, other products are not included. 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.
