Item Type: MK-328 Transistor Tester

1. Key operation for automatic shutdown
2. Battery operation is possible because the shutdown current is only about 20mA
3. Automatic detection of NPN and PNP bipolar transistors, N- and P-channel MOSFETs, JFETs, diodes, dual diodes, unidirectional thyristors and bidirectional thyristors.
4. Automatically detect the pin layout of the detected parts.
5. Measure the current amplification factor of the bipolar transistor and the voltage of the base emitter threshold
6. Darlington transistor can be identified by the threshold voltage of high current amplification factor.
7. Measure the gate threshold voltage and gate capacity for MOSFET.
8. Measure and display up to four decimal digit values in the right dimension. All symbols are surrounded by the probe number of the Tester.So potentiometer. If the potentiometer is adjusted to one of its ends, the tester cannot distinguish the middle pin from the end pin.
9. The resistance measurement with resolution is 0.1° and can measure up to 50MΩ
10. Can detect and measure a capacitor. It displays numbers with up to four decimal places in the right dimension. The value can be from 30pF to 100mF. The resolution can get 1pF.
11. For those with a capacity value higher than 2μF equivalent. The serial resistance () has a resolution of 0.01Ω and displays two significant decimal digits.
12. Up to two diodes are displayed in the correct order and diode symbol. In addition, the forward voltage is also displayed.
13. The LED is detected as a diode; the forward voltage is much higher than the normal voltage. Two-to-one LEDs are also detected as two diodes.
14. If the reverse fault voltage is lower than 4.5 V, the Zener diode can be identified
15. Measure the capacity of a single diode in the opposite direction. If the base is connected and only one collector or emitter is connected, the bipolar transistor can also be analyzed
16. Only
