Multifunction Meter DIY kit, kuman Mega 328 Graphic transistor Tester, NPN PNP Diodes Triode Capacitor ESR SCR MOSFET Resistor Inductance LCD Display Checker with case and screwdriver K77


1.Add boot voltage detection function 
2. Automatic detection of NPN and PNP transistors, N -channel and P-channel MOSFET, diodes (including dual diode), thyristors, transistors, resistors and capacitors and other components 
3. Automatic test out the pin element and displayed on the LCD 
4. Can be detected to determine the transistor emitter forward bias voltage of the transistor, MOSFET protection diode and the amplification factor of the base 
5. Measure the gate threshold voltage and gate capacitance of the MOSFET 
6. 1602 lcd display uses LCD (12864 LCD with backlight) 
7. High test speed, valid component test: 2 seconds (except in the larger capacitor of large capacitance measurement also takes a long time , the measured time of one minute is normal) 
8. One button operation , power-on test , get a key 
9. Power consumption off mode : less than 20 nA of 10. Auto power off function to avoid unnecessary waste, saving battery power, improved battery life. 
Test ranges: Inductors, capacitors , diodes, dual diode , mos, transistor, SCR , the regulator, LED tube , ESR, Resistance, Adjustable potentiometer Resistance: 0.1 ohm resolution, maximum 50M ohm 
Capacitor: 25pf -100,000 uf 
Inductors: 0.01mh-20H 

Before measuring capacitance, the capacitor must be discharged, otherwise very likely damage the meter. 
Package includes: 
1 x Mega328 Transistor Tester ESR Meter 
1 x Clear case
