LCR-T4 ESR Meter Digital Combo Transistor Tester Diode Triode Inductor Capacitance Resistor MOS/PNP/NPN+Test Clip With Case

Compact MTY328P / M328-style component tester for checking common electronic parts on the bench, including transistors, MOSFETs, diodes, resistors, capacitors, inductors, SCRs, LEDs, and ESR-related measurements.

Key Functions

• Automatic detection for NPN/PNP transistors, N-channel/P-channel MOSFETs, JFETs, diodes, dual diodes, thyristors, resistors, capacitors, inductors, LEDs, and adjustable potentiometers.
• Displays detected pin arrangement and basic component parameters on a 128x64 backlight LCD.
• Can identify transistor gain, base-emitter threshold voltage, MOSFET gate threshold voltage, and gate capacitance.
• Supports resistance, capacitance, inductance, diode forward voltage, diode reverse capacitance, and ESR-style checks for suitable components.

Measurement Ranges

• Resistance: 0.1 ohm resolution, up to 50M ohm.
• Capacitance: approximately 25pF to 100,000uF; original description also notes 30pF to 100mF range depending on component/test condition.
• Inductance: approximately 0.01mH to 20H.
• ESR display resolution: 0.01 ohm for suitable capacitors.

Power and Package Notes

• Uses a 9V battery; battery is not included.
• Package and accessory options vary by selected variant. Check the selected option before ordering.
• Discharge capacitors before measurement to avoid damaging the tester.
