MK-328 Transistor Tester, Inductance Capacitance Resistance Electronic Meter, Portable Transistor, TR ESR Meter

Shrnutí

• The resistance uses 1 degree metal film resistor, with good performance. Strict quality control and quality assurance, high safety factor, can be used with peace of mind. Using high-quality materials, strong and durable, has a long service life. Can automatically detect the pin layout of detected parts. Measure the current amplification factor of the bipolar transistor and the voltage of the base emitter threshold.
• Key operation for automatic shutdow; Battery operation is possible because the shutdown current is only about 20mA; Automatic detection of NPN and PNP bipolar transistors, N- and P-channel MOSFETs, JFETs, diodes, dual diodes, unidirectional thyristors and bidirectional thyristors; Automatically detect the pin layout of the detected parts; Measure the current amplification factor of the bipolar transistor and the voltage of the base emitter threshol.
• Darlington transistor can be identified by the threshold voltage of high current amplification factor; Measure the gate threshold voltage and gate capacity for MOSFET; 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.
• The resistance measurement with resolution is 0.1 degree and can measure up to 50M; 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; For those with a capacity value higher than 2μF equivalent. The serial resistance (ESR) has a resolution of 0.01 ohm and displays two significant decimal digits.
• Up to two diodes are displayed in the correct order and diode symbol. In addition, the forward voltage is also displayed; 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; If the reverse fault voltage is lower than 4.5 V, the Zener diode can be identified.
