Feature: 1. Digital LCD display: Transistor tester is easy to read, displaying measurement data and graphs, rotating switch control, convenient button measurement.2. 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. 3. Square Generator: Multi range square frequency, rotate the left and right test button to switch different square frequencies, long press the test button to exit the square generator. 4. Pulse 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. 5. 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. Specification: Item Type: Transistor Tester Package List: 1 x Transistor Tester1 x Knob Cover 1 x Storage Box Note: Before testing the capacitance, discharge the capacitor before inserting it into the test holder for measurement, otherwise the tester's microcontroller may be damaged.
