This is an economical and widely used transistor detector. It can detect NPN and PNP transistors, capacitors, resistors, diodes, triodes, N-channel and P-channel MOSFETs, triacs, and batteries. It is also capable of detecting infrared waveforms. The device features automatic detection of various components including NPN and PNP transistors, capacitors, resistors, diodes, triodes, MOSFETs, IGBTs, JFETs, and triacs. It supports Zener diode detection and includes a self-calibration function. To use the infrared detection feature, align the infrared remote control with the "IR" sensor and press a button on the remote. If the signal is decoded, the detector will display the data code and infrared waveform. Detection starts and stops automatically with a single button press. The multifunction button can be used to power off the device. Insert the component leads into the designated test area, turn the selector knob, and the device will automatically perform the test. Results are displayed on a backlit TFT screen. Unlike standard monochrome displays, this detector provides color display output.
