Technical specifications: for reference
1. One-button operation, automatic shutdown.
2. The shutdown current is only 20 Na.
3. Automatic detection of NPN, PNP, N-channel and P-channel field effect transistors,
JFET, diodes, two diodes, low-power unidirectional and bidirectional thyristors.
4. Location of contacts of automatic identification components.
5. Measurement of the current gain of the bipolar transistor and the threshold voltage of the base emitter.
6. Through the base-emitter threshold voltage and high current gain to determine Darlington transistors.
7. Can detect bipolar transistors and protective mosfet diodes.
8. Measurement of the threshold voltage of the MOS FET gate and the gate capacitance.
9. Can measure two resistors at the same time and display the resistor symbol.
It is displayed on the right with a decimal value of 4.
The resistance symbol on both sides shows the contact number.
So you can measure the potentiometer.
If the wiper of the potentiometer is not moved to the extreme position,
We can distinguish the middle and both ends of the pin.
10. The resolution of the resistance measurement is 0.1 ohm, 50mohm can be measured.
11. Can measure capacitance from 30 pF to 100 MF, resolution 1 pF.
Additional 12.2 UF capacitors can simultaneously measure equivalent values of the EPS series resistance.
Both can be displayed with decimal value, 0.01 ohm resolution.
13. Can be in the correct order, and the diode symbol displays two diodes and gives the forward voltage of the diode.
14 LED OD is defined as the forward voltage of the diode above. The combination of LED LEDs is defined as two diodes.
15. Reverse decay voltage less than 4.5 V. The zener diode can be identified.
16. Can measure the reverse capacitance of a single diode.
If the bipolar transistor is connected to the base and collector or emitter of the contact,
It can measure the reverse capacitance of the collector or emitter junction.
