Automatic detection PNP and NPN type bipolar transistors , N, P -channel MOSFET, JFET FET , diodes , two diodes, thyristors , resistors , capacitors , inductors.
Automatic detection pin definitions.
Measurement of the bipolar transistor current amplification factor (B) and conduction voltage emitter junction (Uf).
Darlington transistor may be identified by the amplification factor of the high threshold voltage and high current.
Can be detected inside the bipolar transistor and MOSFET protection diodes and displayed on the screen.
The threshold voltage and the MOSFET gate capacitance measurement.
Support two measuring resistors , the potential can also be measured .
If the potentiometer is adjusted to its end , the tester can not distinguish the two ends of the pin and the middle.
Resistance measurement resolution is 0.1Ohm , the highest measurement value of 50MOhm.
Capacitance measurement range from 25pf to 100mF (10UF). Resolution up to 1PF.
Can detect more than 2UF capacitor equivalent series resistance (ESR), with a resolution of 0.01Ohm.
This feature is very important for the detection capacitor performance.
You can display symbols of the two diodes in the right direction , also shows the forward voltage drop.
LED detection of diode forward voltage drop higher than normal.
Dual LED detected as double diodes.
Simultaneous detection of light-emitting diodes will flash.
Each test time is about two seconds , only large capacitance and inductance measurements will take a long time.
