6. Operating Instructions
The DTS6619-016 meter features an LCD display and two control buttons: "TURN" and "SET".

Figure 6.1: Front view of the DTS6619-016 energy meter, showing the LCD display and the "TURN" and "SET" buttons.
- Power-On: Upon power-on, the meter will display the total active energy (kWh).
- "TURN" Button: Press the "TURN" button to cycle through different display parameters such as total power, current (L1, L2, L3), voltage (L1, L2, L3), instantaneous power, power factor, and frequency.
- "SET" Button: The "SET" button is typically used for configuration or resetting certain parameters. Refer to the detailed technical documentation for advanced settings if available. For basic operation, the "TURN" button is sufficient for viewing data.
- Backlight: The LCD display includes a backlight for improved visibility.
- Pulse Indicator: The "PULSE" LED will flash to indicate energy consumption.
- RS485 Communication: The meter supports RS485 for remote data reading. Consult the RS485 communication protocol documentation for integration with monitoring systems.
7. Maintenance
The EVTSCAN DTS6619-016 energy meter is designed for minimal maintenance.
- Cleaning: Periodically clean the exterior of the meter with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspection: Regularly inspect the wiring connections to ensure they remain tight and free from corrosion.
- Environment: Ensure the operating environment remains within the specified temperature and humidity ranges to prolong the meter's lifespan.
- No User Serviceable Parts: There are no user-serviceable parts inside the meter. Do not attempt to open or repair the device.
8. Troubleshooting
If you encounter issues with your energy meter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display / Meter not powering on | No power supply; Incorrect wiring; Internal fault. | Check power supply to the meter. Verify wiring connections according to the diagram. If problem persists, contact support. |
| Incorrect readings | Incorrect wiring; Meter not calibrated (unlikely for new unit); External interference. | Verify all wiring connections. Ensure the meter is installed correctly for a 3-phase 4-wire system. If readings are consistently inaccurate, contact support. |
| PULSE LED not flashing | No load connected; Meter not receiving power; Internal fault. | Ensure there is an active load connected to the circuit being measured. Check power supply. If problem persists, contact support. |
| RS485 communication failure | Incorrect RS485 wiring; Incorrect communication settings; Device address conflict. | Verify RS485 A+ and B- connections. Check communication parameters (baud rate, parity, stop bits). Ensure unique device addresses if multiple meters are on the bus. |
