<p>Function introduction:</p> <p>1. One-button measurement operation will automatically turn off the power supply after a delay. The turn-off current is only 20 nA, supporting battery operation.</p> <p>2. Automatically detect NPN and PNP bipolar transistor, N P channel MOSFET, JFET field effect transistor, diode, double diode, thyristor, resistance, capacitance, inductance. Automatically detect pin definitions.</p> <p>3. Measure the current amplification factor (B) and the conduction voltage (UF) of the bipolar transistor. transistor can be identified by high threshold voltage and high current amplification factor.</p> <p>4. It can detect the protection diode inside the bipolar transistor and MOSFET and display it on the screen.</p> <p>5. Measure the threshold voltage and gate capacitance of MOSFET.</p> <p>6. It supports the measurement of two resistances, and the potentiometer can also measure. If the potentiometer is adjusted to one end of it, the tester cannot distinguish between the middle and two ends of the pins.</p> <p>7. The resolution of resistance measurement is 0.1 ohm, and the maximum measured value is 50M ohm.</p> <p>8. The capacitance measurement range is from 25pf to 100mF. The resolution shell is up to 1pF, and the inductance measurement range is 0.01MH-20H. If it is lower than 0.01MH, it will be displayed as resistance.</p> <p>9. It can detect the equivalent series resistance () of capacitors above 2UF with a resolution of 0.01 ohm. This function is very important for detecting the performance of capacitors.</p> <p>10. It can display the coincidence of the two diodes in the correct direction and the positive voltage drop at the same time.</p> <p>11. LED is detected as a diode, and the forward voltage drop is higher than the normal value. Double LED detection and double LED, the LED will flash at the same time.</p> <p>Product name: M8 transistor tester kitProduct model: TJ-56-102</p> <p>Working voltage: DC9V DC power supply (9V stacked battery)</p> <p>Shell size: 88 x 88 x 26mm</p> <p>Circuit board size: 81 x 81mm</p> <p>Colour: as shown</p> <p>Material: PCB+components</p> <p>Package Contents:</p> <p>1*M8 transistor tester kit(Excluding battery and case)</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
