- Capacitor: 30pF ~ 100mF
- Inductance: 0.01MH ~ 10H
- Working voltage: can use 6FF22 9V Battery, or DC 5.5V ~ 12V via DC socket
- Controller: ATmega328 (has been programmed)
- Standby current: 0.02uA
- Operating current: 25mA
- auto power off delay
- Shutdown current is only 20nA
- support battery operation
- 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.
