LCR ESR Meter Mega328 Digital Combo Transistor Tester Diode Triode inductor Capacitance resistor MOS/PNP/NPN + Test clip

Additional Feature:

1. The square wave signal generator, optional built-in within the range of 1HZ-2MHZ stall square wave signal;
2.PWM pulse signal generator for 1-99% of the pulse width modulated signal;
3. The frequency meter function, can test 1HZ-25KHZ or higher frequency signal (in this case a slight decrease in accuracy)

How to use:
1. Resistor welding. If you are not familiar with the chromatic circles, please check the resistance with a multimeter.
2. Other components welding. Please make sure the transistor type and direction are correct.
3. Connect with power supply(9V battery or 5.5V-12V external DC power supply) instead of connecting with M328 and the LCD. Then measure the voltage between pin 7 and pin 22 with a multimeter. If the voltage is +5V, it means the meter is working in normal condition.
4. Cut off the power supply, connect with M328 and the LCD. When all installation finished, connect with the power supply.
