3. Automatic detection of NPN, PNP bipolar transistors, N-channel and P-channel MOS field effect transistors, junction field effect transistors, diodes, diodes, thyristors, low power unidirectional and bidirectional thyristors
4. Automatically identify component pin arrangement
5. Measurement of Bipolar Transistor Current Amplification Factor and Base-Emitter Threshold Voltage
6. Identification of Darlington transistor by base-emitter threshold voltage and large current amplification factor
7. Detects bipolar and MOS transistor protection diodes
8. Gate MOS FET threshold voltage and gate capacitance measurement
9. Two resistances and resistance symbol display can be measured simultaneously. The decimal value shown on the right is 4. The resistance symbols on both sides show the number of pins. So you can measure the potentiometer. If the potentiometer wiper is not shifted to the extreme position, we can distinguish the middle and both ends of the needle
10. Resistance measurement resolution is 0.1Ω, can measure 50MΩ
11. Can measure 325pf-100mf capacitor with 1pf resolution
12. 2uf more capacitors can measure equivalent series resistance at the same time. Two can be displayed as decimal values ??with a resolution of 0.01Ω
13. The two diodes can be displayed with the diode symbol in the correct order, and the diode forward voltage can be given.
14. The LED was detected as having a higher diode forward voltage. The combination of LEDs is identified as two diodes
15. Can measure a single diode reverse capacitance. If the bipolar transistor is connected to the collector or emitter of the base and pins, the collector or emitter junction reverse capacitance can be measured
16. Can be connected with single measurement rectifier bridge
