LCR-T4 Mega328 Transistor Tester Diode Resistor Capacitor Tester ESR Meter




1. Digital 128*64 LCD display for easy readings, can display measured data and graphics.

2. Short detection time: only 1.7 seconds. It is normal to take 1 minute for bulk capacitor detection

3. Automatic detection of NPN and PNP transistors, N-channel and P-channel MOSFET, diodes, triodes, resistors, capacitors or other devices

4. Use 9V battery(not included), can also use DC power(DC 6.8-12V). Automatic shutdown, shutdown current is only about 20mA.

5. Measure the gate threshold voltage and gate capacitance of the MOSFET,Measure bipolar transistor current amplification factor and base-emitter threshold voltage
