Product title is labeled as "DIY kit" of both parts, you need your own assembled by welding, to demonstrate for convenience, the main picture of the products is a physical map, the second picrure is all the parts you receive, be sure to pay attention to the distinction Description: 1. Resistors, capacitors, inductors, coils, diodes, transistors, SCR and most commonly used devices will automatically identify and measure2 . The ability to measure line capacitance and ESR 3. The square wave generator4 .The PWM pulse signal generator5 . The frequency counter function6 . The graphic display of measurement results, easy and intuitive, the whole operation is performed by a rotary control encoder switch control, easy to operate. Feature: Power supply voltage: Main function: 1 . One-button measurement function, automatic power off delay . Shutdown current is only 20nA, support for battery operation2 : Automatic detection of PNP and NPN bipolar transistors, N, P channel MOSFET, JFET field effect transistors, diodes, two diodes, thyristors, resistors, capacitors, coils. Automatic detection of current amplification factor (B) Pin Definitions and activation voltage of transistor and emitter junction (Uf), Darlington transistor through high threshold voltage and high current gain identification. 3: It can detect bipolar transistor and internal MOSFET protection diode and display on the screen. It can measure the threshold voltage and gate capacitance of MOSFET. 4: Supports two resistance measurements, can also measure the potential. The highest resolution is 0.1 ohm resistance measurements, the highest measured value of 50M Euro. 5: Capacitance measurement range from 25pf to 100mF (10 ???? UF). Resolution up to 1 pF. Capacitance of 0.09UF can be detected over equivalent series resistance (ESR), resolution 0.01 ohm. To display the capacitor voltage loss value and increase the capacitance of a separate line ESR measurements, available online (in-circuit) direct measurement capacitor value and ESR, easy maintenance and troubleshooting capacitance problems. 6. Measurement range of inductance 0.01MH-20H, otherwise it will appear as resistance, if the DC resistance of the inductor is higher than 2100 will appear as European resistance. 7. It can display two diode symbols in the right direction, displaying the voltage drop forward. The LED detected as forward diode voltage drop higher than normal. Dual LED lights are detected as a double diode. Simultaneous detection LED flashes, very intuitive. 8. Each test time is about two seconds, only high capacitance and high inductance measurements will take a long time Additional feature: 1. Square wave signal generator, optionally integrated into the 1HZ-2MHZ stop square wave signal range; 2. PWM pulse signal generator for 1-99% of the amplitude-modulated pulse signal . 3. Frequency counter function, can test 1HZ-25KHZ or higher frequency signal (in this case a slight reduction in accuracy) Package includes: 1 x DIY M12864 Graphics Version Transistor Tester Kit LCR ESR PWM
