And it can automatically recognize the foot position (polarity) and display relevant parameters in graphics (such as magnification, , etc.) automatic measurement and testing of parameters related to diodes, transistors, resistors, capacitors, and inductors The instrument is easy to use as long as the components are placed in the testing area and the button is pressed. Capable of measuring transistors, MOS transistors, thyristors, transistors, IGBTs(Note: high-power thyristor, IGBT, may not be tested accurately) Can test the encoding value of infrared remote control (only supports format).The instrument comes with a lithium battery and does not require an external battery to be equipped with a USB charging cable, Weight: 0.31305641204 Pounds, Manufacturer: Jaywool
