Made of high-quality material, durable and practical. Small size, simple application, convenient installation. Efficient and stable performance, long working life. Can automatically identify the pin position and display it graphically with large screen graphic display, easy to read and observe. Wide range of applications, with infrared waveform display and infrared receiving instructions. Easy to use: simply place the component in the testing area and press the START button to begin automatic measurement. Capable of testing parameters related to diodes, transistors, resistors, capacitors, and inductors. Capable of testing transistors, MOS transistors, thyristors, and Darlington transistors. IGBT (note: high-power thyristor and IGBT may not be tested accurately). Can automatically recognize pin position and display it in graphics. Can test the code value of infrared remote controls (supports NEC format only). Power supply: 2x AAA batteries (batteries not included). Attention: Before testing the capacitor, it must be discharged first; otherwise, it may damage the instrument. This instrument is an active device and should not be used to measure live circuit boards, as it may cause damage to the circuit board. Color: red Material: plastic Package Contents: 1 x Digital Transistor Tester Only the above package content is included; other items are not included. Note: Light reflection and different displays may cause the color of the item in the picture to differ slightly from the actual product. Measurement error allowance is +/- 1-3 cm.
