Item Type: MK-328 Transistor Tester_x000D_ _x000D_ 1. Key operation for automatic shutdown_x000D_ 2. Battery operation is possible because the shutdown current is only about 20mA_x000D_ 3. Automatic detection of NPN and PNP bipolar transistors, N- and P-channel MOSFETs, JFETs, diodes, dual diodes, unidirectional thyristors and bidirectional thyristors._x000D_ 4. Automatically detect the pin layout of the detected parts._x000D_ 5. Measure the current amplification factor of the bipolar transistor and the voltage of the base emitter threshold_x000D_ 6. Darlington transistor can be identified by the threshold voltage of high current amplification factor._x000D_ 7. Measure the gate threshold voltage and gate capacity for MOSFET._x000D_ 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._x000D_ 9. The resistance measurement with resolution is 0.1 and can measure up to 50M_x000D_ 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._x000D_ 11. For those with a capacity value higher than 2F equivalent. The serial resistance (ESR) has a resolution of 0.01 and displays two significant decimal digits._x000D_ 12. Up to two diodes are displayed in the correct order and diode symbol. In addition, the forward voltage is also displayed._x000D_ 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._x000D_ 14. If the reverse fault voltage is lower than 4.5 V, the Zener diode can be identified_x000D_ 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_x000D_ 16. Only one measurement is needed to find the connection of the rectifier bridge._x000D_ 17. Capacitors with values ??lower than 30pF cannot usually be detected, but they can be measured together with parallel diodes or parallel capacitors of at least 30pF.In, so the capacity value of the parallel components must be subtracted._x000D_ 18. Can measure the inductance resistance is less than 2100, the measurement range is 0.01mH + 20H, but the accuracy is not very good. The measurement result is displayed only when a single component is connected._x000D_ 19. The test time is about two seconds. Only the capacity or inductance measurement can extend the period.
