Yosoo GM328 Lcd Display Transistor Tester ESR Meter Cymometer Square Wave Generator

• using the latest 2014 version V1.11 software, M328 chip, more features
• micro-controller uses 8MHz external crystal, measurement accuracy is better.
• LCD using 12864 LCD screen that can display measured data and graphics.
• main chip dual in-line with a socket, ideal for electronics enthusiasts upgrade or replace the chip.
• Current: When 9V voltage, stable operating current of about 20mA.

Product Description: LCR-T3 graphical multi-function tester resistor capacitor + + + SCR + diode + transistor + mos tube inductance LCD 12864 LCD display, with backlight , backlight color is generally yellow-green 9v battery powering stacked . If prolonged power , you can use two 8.4v lithium battery pack consisting of Function: 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 Notice: Before measuring capacitance , the capacitor must be discharged , otherwise very likely damage the meter Package include: 1 x LCR-T3 Graphical Multi-function Tester
