2014 New Transistor Tester Capacitor ESR Inductance Resistor Meter NPN PNP Mosfet (It's not DIY kit .have soldered .you can use it directly )instruction send by email Description: the new version of the transistor tester since 2013.12.24 officially on sale , using ATMEGA168 chip ( using ATMEGA328 functions with identical ) , more powerful , in addition to all the features of the original M8 version , increasing the inductance and capacitance ESR measurement function , increasing the external circuit crystal and precision voltage reference , the measurement accuracy is greatly improved, and use low-dropout voltage regulator circuit , the power to adapt to a wider range, battery life greatly increased, while the design of external power socket, you can use the 5.5-12V DC power supply ( some Vintage charger voltage is 5.5V, but can not use 5VUSB power ) . Offers a variety of installation methods , easier to use ! Using blue and white LCD , clear and beautiful ! Shooting light causes physical display sharper than the picture ! PCB selection of military plates, giant machining , precision better ! Please note that the button is the key direction of welding : Attention ! To access the circuit often start ! Now many are fed back problems did not pay attention to the direction of the results of this component installed backwards ! This is a more intelligent than the multimeter measuring instrument , called a good helper electronics enthusiasts , with powerful measurement functions , automatic identification of various types of components , parameters, pin definitions , just a button to automatically measure ! Battery-powered portable design , you can even take it to the store pick elements ! Also has an external power supply function , the use of more economical for a long time in the indoor convenience ! Features: 1 : a key measurement operation , auto power off delay . Shutdown current is only 20nA, support battery operation. 2 : Automatic detection PNP and NPN type bipolar transistors , N, P -channel MOSFET, JFET FET , diodes , two diodes, thyristors , resistors , capacitors , inductors . Automatic detection pin definitions. 3 : Measurement of the bipolar transistor current amplification factor (B) and conduction voltage emitter junction (Uf). Darlington transistor may be identified by the amplification factor of the high threshold voltage and high current . 4 : can be detected inside the bipolar transistor and MOSFET protection diodes and displayed on the screen. 5 : the threshold voltage and the MOSFET gate capacitance measurement . 6: Support two measuring resistors , the potential can also be measured . If the potentiometer is adjusted to its end , the tester can not distinguish the two ends of the pin and the middle . 7 : Resistance measurement resolution is 0.1 ohm , the highest measurement value of 50M ohms. 8: capacitance measurement range from 25pf to 100mF (10UF). Resolution up to 1 pF. 9: can detect more than 2UF capacitor equivalent series resistance (ESR), with a resolution of 0.01 ohms. This feature is very important for the detection capacitor performance. 10 : You can display symbols of the two diodes in the right direction , also shows the forward voltage drop . 11: LED detection of diode forward voltage drop higher than normal . Dual LED detected as double diodes. Simultaneous detection of light-emitting diodes will flash . 12: each test time is about two seconds , only large capacitance and inductance measurements will take a long time . The following is an actual measurement , the use of an external 9V power supply ( negative polarity outside the positive ) : Notice: Before measuring capacitance , the capacitor must be discharged , otherwise very likely damage the meter .
