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 foot position and can be displayed as a graphic, 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. Start automatic measurement Capable of testing parameters related to diodes, transistors, resistors, capacitors, and inductors Capable of testing transistors, MOS transistors, thyristors, Darlington transistors, IGBT (note: high-power thyristor, IGBT, may not be tested accurately) And can automatically recognize the foot position and display it in graphics Can test the encoding value of infrared remote control (only supports NEC format) Power supply: 2xAAA batteries(Not included batteries)) Attention: Before testing the capacitor, it is necessary to discharge it first. Otherwise, it will directly damage the instrument This instrument is an active instrument and should not be used to measure live circuit boards. May cause damage to the circuit board Colour:red Material:plastic Package Contents: 1 x Digital Transistor Tester
