Important Installation Notes:
- Incorrect wiring with voltage will damage the meter. Always ensure connections are made according to the diagram.
- This meter is designed exclusively for measuring 50Hz AC city electricity. Do not use it to measure square wave, inverter output, or corrected sine wave signals, as this will damage the device.
5. Operation
Once properly installed and powered, the meter will automatically begin displaying measurements.
Resetting Electric Energy:
To reset the accumulated electric energy (kWh) reading to zero, press and hold the button on the meter for approximately 5 seconds. The electric energy value will then reset.
6. Maintenance
The D85-2058 meter is designed for low maintenance. It features an auto-saving function that preserves electric energy data even after power loss, resuming accumulation when power is restored.
- Keep the device clean and dry. Use a soft, dry cloth for cleaning.
- Avoid exposing the meter to extreme temperatures, humidity, or corrosive environments.
- Do not attempt to open or repair the meter yourself. Refer to qualified personnel for service.
7. Troubleshooting
If you encounter issues with your D85-2058 meter, consider the following:
- No Display or Incorrect Readings:
- Verify that the power supply is connected correctly and is within the specified AC 200-450V range.
- Ensure all wiring, especially the voltage input and current transformer connections, are secure and match the installation diagram.
- Confirm that the power source is 50Hz AC city electricity. The meter is not compatible with square wave, inverter output, or corrected sine wave power.
- Electric Energy Not Resetting:
- Ensure you are pressing and holding the reset button for the full 5 seconds.
If problems persist after checking these points, contact the seller or manufacturer for further assistance.
8. Safety Information
Please read and adhere to the following safety guidelines to prevent injury or damage to the device:
- Always disconnect power before performing any installation, wiring, or maintenance on the meter.
- Only qualified and experienced personnel should perform electrical installations and wiring.
- Do not use the meter outside its specified voltage (AC 200-450V) and frequency (50Hz) ranges.
- Avoid touching live terminals or wires when the meter is powered.
- Ensure the meter is installed in a dry, well-ventilated area, away from direct sunlight, heat sources, and corrosive gases.
