1. Introduction
The Treedix LCR-TC1 is a versatile multi-function tester designed for electronic component analysis. It features a 1.8-inch TFT graphic display and is capable of automatically identifying and measuring various components, including transistors, diodes, resistors, capacitors, and inductors. This manual provides essential information for the safe and effective use of your device.
2. Safety Information
Please read and understand the following safety precautions before operating the device:
- The device contains a built-in Li-ion battery. Do not immerse the tester in water or expose it to high heat sources.
- Always discharge capacitors before connecting them to the tester. Failure to do so can damage the device and pose a safety risk.
- It is not recommended to use this tester to measure batteries directly. If measuring a battery, ensure its voltage is less than 4.5V to prevent damage to the tester.
- Do not attempt to test components while they are still connected in a live circuit.
- Handle the test leads and components with care to avoid damage to the device or injury.

5. Setup
5.1 Initial Charging
Before first use, fully charge the internal lithium battery using the provided USB cable. Connect the cable to the micro-USB port on the side of the tester and to a standard USB power source (e.g., computer USB port, USB wall adapter).
5.2 Connecting Test Hooks
The three test hooks can be connected to the corresponding test points (1, 2, 3) on the ZIF socket for easier testing of larger components or components not suitable for direct insertion into the ZIF socket.
5.3 Calibration
The LCR-TC1 features an automatic calibration function. To perform calibration:
- Ensure no components are inserted into the ZIF socket or connected to the test points.
- Short-circuit all three test points (1, 2, 3) together using a wire or by connecting the three test hooks together.
- Press and hold the 'Start' button. The device will prompt for calibration.
- Follow the on-screen instructions. The device will guide you through removing the short circuit when prompted.
- Calibration is complete when the device returns to the main measurement screen.
6. Operating Instructions
6.1 Basic Component Testing
To test a component:
- Ensure the component is discharged (especially capacitors) and not connected to any live circuit.
- Insert the component's leads into the ZIF socket (pins 1, 2, 3) or connect them using the test hooks to the corresponding test points. The order of pins does not typically matter as the tester automatically identifies them.
- Close the ZIF socket lever if using the socket.
- Press the 'Start' button.
- The tester will automatically detect the component type and display its parameters on the TFT screen.
