Description: Description Measuring range automatic detection of PNP and NPN bipolar transistors N and P channel MOSFETs JFET field effect tubes diodes double diodes SCRs resistance capacitance and inductance Features 1 One key measurement operation power off automatically after delay The shutdown current is only 20nA which supports battery operation 2 Automatic detection of PNP and NPN bipolar transistors N P channel MOSFETs JFET field effect transistors diodes double diodes SCRs resistors capacitors and inductors Automatically detect pin definitions 3 Measure the current amplification factor B of the bipolar transistor and the conduction voltage Uf of the emitter junction Darlington transistors can be identified by high threshold voltage and high current amplification factor 4 The protection diodes inside bipolar transistors and MOSFETs can be detected and displayed on the screen 5 Measure the threshold voltage and gate capacitance of the MOSFET 6 Support the measurement of two resistances and the potentiometer can also be measured If the potentiometer is adjusted to one end of it the tester cannot distinguish the pins in the middle and both ends 7 The resolution of resistance measurement is 0 1 ohm and the highest measurement value is 50M ohm 8 The capacitance measurement range is from 25pf to 100mF 100 000 UF The resolution can reach 1 pF the inductance measurement range is 0 01MH 20H and it will be displayed as resistance if it is lower than
