1.Highly Accurate Measurements: Microcontroller using 8MHz external crystal, better measurement accuracy. Automatically detect NPN, PNP bipolar transistors, Nchannel and Pchannel MOS FET, JFET, diodes, dual diode, thyristor small power unidirectional and bidirectional thyristor 2.Multifunction Component Test: This multifunction meter can test diodes, transistors, capacitors, resistors, RLC, LCR and more. It is suitable for both low power unidirectional and bidirectional thyristors, making it a versatile tool for electronics hobbyists and professionals 3.UserFriendly Design: Onebutton operation and automatic shutdown make this tester easy to use. Its low shutdown current of 20nA ensures long battery life. Each test takes approximately 2 seconds, with longer test times for large capacitors and inductors 4.Fine Workmanship: Put the pins of component in corresponding area, then dial the little handle and the detector will test it automatically, finally the results will display on the back light TFT screen clearly. Fine workmanship and good performance Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Dadangjia
