1. One key measure operation, time delay automatic power off. Turn off the current only 20mA, to support the operation of the battery.
2. Automatic detection of PNP and NPN bipolar transistor, N, P channel JFET, MOSFET field effect transistor, diode, dual diode, thyristor, resistance, capacitance, inductance.
Automatic detection pin definition.
3. Measurement of the bipolar transistor current amplification factor (B) and the conduction voltage of the emitter junction (Uf). Darlington transistor can be identified by high threshold voltage and high current amplification factor.
4. Can detect the bipolar transistor and MOSFET inside the protective diode and displayed on the screen.
5. Measurement of MOSFET threshold voltage and gate capacitance value.
6. Support for the measurement of two resistors, the potentiometer can also be measured.
If the potentiometer is adjusted to the end of it, the tester can not distinguish between the middle and both ends of the pin.
7. The resolution of the measurement of resistance is 0.1 ohm, the highest measured value of 50M ohm.
8. Capacitance measurement range from 25pf to 100mF (100 thousand UF). Resolution of up to 1 pF, inductance measurement range of 0.01MH-20H, otherwise it will be displayed as a resistance, if the inductance of the DC resistance value is higher than 2100 ohm.
9. Can detect 2UF above the capacitor equivalent series resistance (ESR), with a resolution of 0.01 ohm. This feature is very important for the detection of capacitive performance.
Capacitance test, the VLoss display on the screen is the loss, attenuation of the meaning of this value is greater, the more close to the scrap it! ESR is the impedance, the smaller the value, the better the performance of the capacitor!
10. Two diodes can display the correct direction of the symbol, while showing the positive pressure drop.
11. LED is detected as a diode, and the forward voltage drop is higher than the normal value.
Dual light emitting diode detector for dual diode. Detection at the same time light-emitting diodes will shine.
12. Each test time is about two seconds, only large capacitance and inductance measurement will take a long time
