5. Setup Instructions
5.1 Physical Placement
Place the LCR meter on a stable, level surface. Ensure adequate ventilation around the instrument. The retractable support frame can be used to adjust the viewing angle for better readability.
5.2 Power Connection
Connect the provided power plug cable to the power interface on the rear panel of the instrument. Ensure the main power control switch is in the OFF position before connecting to a power outlet. The instrument operates on AC 200-240V, 50-60Hz. A fuse (AC 250V 500mA) is integrated for protection.
5.3 Connecting the Kelvin Testing Fixture
For accurate measurements, especially for low impedance components, use the provided Kelvin testing fixture. Connect the fixture to the front panel test terminals as shown in the diagram.
5.4 Interface Connections (Optional)
The instrument supports various interfaces for remote control and data transfer:
- RS232: For serial communication with a computer.
- HANDLER: For connecting to automated test systems.
- GPIB: General Purpose Interface Bus for instrument control.
- LAN: For network connectivity.
- USB: For data storage (USB memory) or PC connection.
Refer to the rear panel diagram (Figure 5.2) for the location of these interfaces.
6. Operating Instructions
6.1 Powering On/Off
To power on the instrument, ensure the power cable is securely connected, then flip the main power control switch on the rear panel to the ON position. Press the power button on the front panel. To power off, press the front panel power button, then flip the main power control switch to OFF.

- Ensure the Kelvin testing fixture is properly connected and the component is securely attached.
- Perform a self-calibration or open/short circuit calibration.
- Check for environmental factors like temperature fluctuations or strong electromagnetic interference.
- Verify the correct test frequency and signal level are selected for the component type.
- No display or garbled display:
- Power cycle the instrument.
- Ensure the display is clean and free from obstructions.
- If the issue persists, contact customer support.
- Communication issues with PC:
- Ensure the correct interface cable (RS232, USB, LAN, GPIB) is used and securely connected.
- Verify the correct drivers are installed on the PC.
- Check communication settings (e.g., baud rate for RS232) match between the instrument and PC software.
9. User Tips
No specific user tips were available from buyer reviews or Q&A for this product. However, general best practices for LCR meters include:
- Always use the Kelvin testing fixture for precise measurements to minimize lead inductance and resistance.
- For very small capacitance or large inductance values, ensure proper shielding and grounding to avoid external interference.
- When measuring components with DC bias, always connect the component before applying bias and disconnect bias before removing the component.
- Keep the instrument and accessories clean and free from dust and moisture.
