Introduction FNIRSI-TC2 ingeniously integrates digital oscilloscope, electronic component tester, PWM signal generator and other functions into one.Equipped with large-size color dot matrix TFT display.Built-in rechargeable lithium battery.Bring more practical functions to users with a small size,Also has good portability. FNIRSI-TC2 has various working modes such as oscilloscope and component tester.Each time you click the power button, it will enter the mode selection interface.Press the [Up] and [Down] keys of the direction keys to select,Select Mos Test item, pressOKkey to enter component tester mode;Select the Oscilloscope item, pressOKkey to enter the oscilloscope mode. "Mos Test" mode can test various types of transistors, and can identify device type, pin polarity, hFE, turn-on voltage, junction capacitance; can test capacitance, resistance, inductance components, etc. FNIRSI-TC2 is especially suitable for fast pairing of transistors, identification of mixed surface mount and wordless components, and preliminary screening of small batch components."Oscilloscope" mode to test the signal waveform of the circuit.Support online operation with computer, you can refresh the official firmware by yourself and complete the upgrade. It is hoped that FNIRSI-TC2 can make the study and work of the majority of users more efficient and interesting.
