FNIRSI LCR-T4 ESR Meter Transistor Tester with TFT Display and Micro USB PowerAuto Component ID | ESR Measurement | ZIF Socket | Micro USB Power

The FNIRSI LCR-T4 ESR Meter Transistor Tester is a multi-purpose device for identifying and testing common electronic components and displaying measured parameters on a color screen.

It automatically detects the component type and presents key readings for tasks such as component identification, circuit debugging, and electronics learning.

Key Features

• Automatic identification: detects the component type and shows its corresponding parameters without manual input.
• Multi-component support: tests transistors, diodes, thyristors, triacs, resistors, capacitors, inductors, zener diodes, and LEDs.
• ESR function: measures ESR of capacitors for diagnosing faulty components.
• Graph mode: provides graphical representation for certain transistors and diodes.
• Result storage: stores test results for analyzing and comparing components.
• Safety protection: includes overload protection and reverse polarity protection.
• Power management: supports auto power-off to conserve battery life.
• Display rotation: supports rotating the screen for easier viewing.

Working Principle

• Auto detection: the tester identifies the connected component type automatically.
• Parameter measurement: it measures key parameters relevant to the detected component and displays them on the screen.
• Display output: measured values and related data are shown directly on the device without external logging or wireless transfer.
