- Automatic Component Detection: Instantly identifies NPN and PNP transistors, N-channel and P-channel MOSFETs, JFETs, diodes (including Zeners), and more.
- 1.8″ Full-Color TFT Display: High-definition graphic interface displays the component symbol, pin configuration, and measured values simultaneously.
- One-Key Operation: Fully automated testing with an auto-power-off feature to conserve battery life.
- Built-in Infrared (IR) Decoder: Capable of decoding IR remote control signals (supports Hitachi coding format); ideal for testing remote control functionality.
- USB Rechargeable: Features an integrated high-capacity Li-ion battery with a Micro-USB charging port—no need for external batteries.
- Self-Calibration Support: Includes a self-test function to ensure measurement accuracy over time

- Power On: Press the multi-function start button to wake the device.
- Component Insertion: Insert the component leads into the test socket (labeled 1, 2, 3). For SMD components, use the integrated testing pads or the included test clips.
- Lock & Test: Close the locking lever of the socket and press the start button.
- Read Results: The device will analyze the component for 2-5 seconds (longer for large capacitors) and display the type, pinout, and parameters (e.g., hFE for transistors or ESR for capacitors).
- IR Testing: Point an IR remote at the “IR” receiver hole and press a button on the remote. The tester will display the data code and waveform if compatible.
- Shutdown: The device will automatically power off after a period of inactivity to save battery
Yes. This is the SUNLEPHANT Original Pre-Assembled version. It is fully calibrated and housed in its professional casing, ready for immediate us
No. You must always remove the component from the circuit and fully discharge capacitors before testing. Testing a charged capacitor or an “in-circuit” component will damage the tester
Absolutely. It is a favorite for QC departments and repair shops because it significantly reduces the time required to identify unmarked or burnt-out components compared to traditional multimeters
The LCR-TC1 provides a reliable ESR reading for capacitors >2µF. While not a laboratory-grade specialized ESR meter, it is excellent for identifying “dried out” electrolytic capacitors in power supplies
The package includes the LCR-TC1 Tester, a set of test clips, a Micro-USB charging cable, and a calibration electronic component set (capacitor/LED)
Yes. Unlike many cheaper testers, the LCR-TC1 has a dedicated Zener diode test area (labeled K-A-A) that can test Zeners up to 30V. Search STMicroelectronics authorized distributors for compatible components
