Feature

●DIGITAL LCD DISPLAY: Transistor tester is easy to read, displaying measurement data and graphs, rotating switch control, convenient button measurement.you can easily monitor the data and allow you to make accurate identification
●FREQUENCY MEASUREMENT: Press and hold the test button to exit the frequency measurement function. Frequency measurement range from 1Hz to more than 1MHz When the measured frequency is lower than 25KHz, the period is displayed.
●SQUARE WAVE GENERATOR: Multi range square wave frequency, rotate the left and right test button to switch different square wave frequencies, long press the test button to exit the square wave generator.Turn the test button to the left or right to adjust the pulse duty cycle from 1% to 99%. Press and hold the test button to exit the pulse generator.
●WIDE APPLICATION: This tester with fine workmanship and excellent testing performance is an ideal replacement for the old and damaged parts,suitable for electronic enthusiasts, electronic developers, designers, and electronic repairers. A necessary small instrument.
●POWER INTERFACE: The transistor tester uses 5V Type C power interface for power supply, or it can be soldered to 9V battery interface for automatic shutdown, and the shutdown current is only about 20nA,made with advanced chip which has a more powerful functions
