Features The microcontroller adopts 8MHz external crystal oscillator, and the measurement accuracy is better. Each test takes about two seconds, only large capacitance and inductance measurements take longer. Automatic detection of NPN, PNP bipolar transistors, JFETs, diodes, dual diodes, thyristors low power unidirectional and bidirectional thyristors. Two diodes can be displayed in the correct order and diode symbol, and the forward voltage of the diodes is given. 100% brand new product, all refund if unsatisfied If you have any questions, please contact our professional customer service team.
