LCR-T4 Meter Transistor/Diode/Capacitance Tester

Automatic Multi-Component Recognition: Intelligently detects and measures NPN/PNP transistors, N/P-channel MOSFETs, JFETs, diodes, dual diodes, thyristors, triacs, resistors, inductors, and capacitors with instant pinout mapping.

12864 Backlit Graphic LCD Display: Features a clear 128 x 64 green backlit LCD screen that simultaneously displays component schematics, pin configurations, and measured electrical values.

One-Touch Automated Operation: Simple single-button operation initiates quick measurement cycles with automatic power-off to minimize 9V battery drain during prolonged bench testing.

Capacitance & ESR Analysis: Tests capacitance from 25 pF to 100 mF (1 pF resolution) with Equivalent Series Resistance (ESR) measurement for troubleshooting degraded electrolytic capacitors.

ZIF Test Socket & Surface Mount Pad: Built-in 14-pin Zero Insertion Force (ZIF) lock-down lever socket alongside a dedicated SMD testing pad for effortless testing of both leaded and surface-mount components.

Board & Socket Assembly: Engineered on a heavy-duty fiberglass PCB with a high-durability locking ZIF socket module and clear LCD screen header.

Measurement Ranges & Specifications:

Resistance: 0.1 ohms - 50 M ohms.

Capacitance: 25 pF- 100 mF.

Inductance: 0.01 mH- 20 H.

Power Source: Powered by a standard 9V PP3 battery (6F22 format, not included).

Crucial Operating Precaution: Always fully discharge all capacitors before connecting them to the ZIF test socket to prevent permanent damage to the microcontroller.

Must-Have Desktop Component Analyzer: Position as an essential, high-value component identifier for electronics repair technicians, hobbyists, and engineers sorting unknown or salvaged parts.

Protective Shell Cross-Sell: Recommend pairing with the custom-fit LCR-T4 Meter Acrylic Case Shell to safeguard the exposed circuit board from accidental bench shorts.

Recommended Cross-Sell Add-ons: Pair with LCR-T4 Meter Acrylic Case Shell, TC-T7-H Full-Color, Multifunction Tester, 60W 220V Electric Soldering Iron Tool Kit, and anti-static tweezers.

High-Volume Workbench Staple: A consistently popular impulse item to bundle into soldering equipment sets, maker kits, and diagnostic tool collections.
