M328 3.7V 20mA Transistor Tester LCR Capacitance ESR Meter

Introdution: 1. The tester uses 3.7V rechargeable lithium battery (battery model: 14500) 2. With MINI USB port,it can power the tester, or charge for the 14500 battery 3. One key measurement operation, auto power off delay. Shutdown current is only 20mA, support for battery operation 4. Automatic detection PNP and NPN bipolar transistor, N, P-channel MOSFET, JFET FET, diodes, two diodes, thyristors, resistors, capacitors, inductors. Automatic detection pin definitions 5. Measuring the current amplification factor (B) of the bipolar transistor and the turn-on voltage of the emitter junction (Uf). Darlington transistor amplification factor can be identified by the high threshold voltage and high current 6. Can detect bipolar transistors and MOSFET's internal protection diodes and displayed on the screen 7. Measuring the threshold voltage and the gate capacitance of the MOSFET 8. Support two resistance measurements, the potential can be measured. If the potentiometer is adjusted to its end, the tester can not distinguish between the middle and the ends of the pin 9. Resistance measurement resolution is 0.1 ohms, the maximum value of 50M ohms measurements 10. Capacitance measurement range from 25pf to 100mF (100000 UF). Resolution up to 1 pF, inductance measurement range 0.01MH-20H, otherwise it will appear as a resistor, inductor DC resistance is higher than if Europe 2100 will also be displayed as a resistor 11. It can detect 2UF above capacitor equivalent series resistance (ESR) a resolution of 0.01 ohms. This feature is very important for the detection of the capacitor performance 12. It can display symbols of the two diodes in the right direction, also shows the forward voltage drop 13. LED detection for diode forward voltage drop higher than normal. Dual LEDs detected as double diode. Simultaneous detection of light-emitting diodes will flash 14. Time for each test is about two seconds, only the large capacitance and inductance measurements will take a long time Notice: 1. How to calibrate: Short three test point, the screen shows into calibration step. When prompted to disconnect the short end,please disconnected three tests points, calibration will continue, plug the capacitance when prompted plug into a capacitance over 100nF between 1 and 3 feet(Please use the nonpolarized capacitors over 100nF),then the program will automatically enter the next step, until the calibration is completed, reboot to complete the correction. 2. When you use the battery first time,please activate the battery: (1) Short the 2 point on the backside as the picture shows after you install the battery (2) Charge the battery after you install the battery Package included: 1 X M328 transistor tester
