Features [Easy Operation]: Transistor tester can 1 click measurement operation, automatic delayed shutdown. The shutdown current is only 20nA and supports battery power supply. Automatic detection of PNP and NPN bipolar transistors, N, P channel MOSFETs, JFET field effect transistor, di [Smart Measurement]: Transistor tester measure the current amplification coefficient B of the bipolar transistor and the conduction voltage Uf of the emission junction. The amplification coefficient of transistors can be identified by high threshold voltage and high current [Clear Display]: Transistor meter accessory can detect the internal protection diodes of bipolar transistors and MOSFETs and display them on the screen. Measure the threshold voltage and gate capacitance of MOSFETs. [The Using Tips]: ESR inductance capacitance meter supports two resistance measurements and can measure potential. If the potentiometer is set to the bottom, the tester cannot distinguish between the middle and both ends of the pin. [High Accuracy]: The resistance measurement resolution is 0.1 ohms, with a maximum measurement value of 50M ohms. The capacitance measurement range is from 25pf to 100mF, that is, 100000 UF. The resolution can get to 1 pF, and the inductance measurement ra Features: 1. Can detect the equivalent series resistance ESR of capacitors above 2UF with a resolution of 0.01 ohm. with a maximum measurement value of 50M ohms. This characteristic is very important for detecting the performance of capacitors. It can display symbols for the correct direction of two diodes and also display forward voltage drop. 2. LED detects whether the forward voltage drop of the diode is higher than normal. Dual LED detection is a dual diode. When the LED is detected at the same time, it will flash. Each test takes approximately two seconds, and only large capacitance and inductance measurements will require a longer time. 3.Using microcontroller. 12864 graphical LCD display of test results. 4. It can detect the protection diodes inside bipolar transistors and MOSFETs and display them on the screen. 5. Measure the threshold voltage and gate capacitance value of MOSFETs. 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 pins in the middle and at both ends.
