Identify Device Type: Oscilloscope mode can test the waveform of the circuit, while Mos test mode can test various types of transistors, which can identify device type, pin polarity, hFE, on state voltage, junction capacitance, resistance, inductive components, etc. generator mode, you can use sine, pulse, triangular or ramp waveform.
Screen: The oscilloscope is powered by a built in 1500 mA battery, which will be fully charged in 12 hours via a 5V 2A adapter and can operate for 4 hours (green indicator for completion/red indicator for charging). The digital handheld pocket oscilloscope and transistor tester is designed with a high resolution 2.4 inch screen with adjusting backlight. Better reading experience and easy to use.
