1.1 VERSATILE TESTING OPTIONS The capacitor resistor transistor triode tester MK-328 provides accurate measurement of capacitors, resistors, transistors and triodes. Whether you need the current gain factor of a transistor or the resistance value of a resistor, this tester delivers reliable results. 2.2 COMPREHENSIVE DIODE TESTING It can check protective diodes in both bipolar transistors and mosfets, helping ensure the reliability and functionality of your electronic devices. It can display up to two diodes with the corresponding symbols, enabling quick identification and troubleshooting. 3.3 MOSFET TESTING MADE EASY The MK-328 tester measures the gate threshold voltage of MOSFETs and also calculates the gate capacitance value. This supports optimization of circuit performance and precise operation. 4.4 HIGH MEASUREMENT RESOLUTION With a high definition resistance measurement function, the tester provides a resolution of 0.1 ohm and can measure from 0.1 ohm to 50 MOhm. This wide range enables testing of a variety of resistance components. Use scenarios - On a repair bench, quickly verify resistors, capacitors, transistors and triodes in radios, amplifiers or handheld devices. - In a lab, check MOSFET gate threshold and gate capacitance to confirm component suitability before design changes. - For field troubleshooting, test protective diodes and diodes inside transistors or MOSFETs to diagnose reliability issues.
