5. Подешавање и инсталација

Follow these steps for proper installation of the power meter:

1. Искључите напајање: Before starting any wiring, ensure that the main power supply to the circuit is completely disconnected to prevent electrical shock.
2. Mount the Meter: Choose a suitable indoor location for the meter. The meter is designed for panel mounting.
3. Повежите напајање: Connect the AC 80-260V power supply to the meter's input terminals as shown in the wiring diagram. Ensure correct polarity if applicable, though for AC, line and neutral are typically interchangeable for the meter's power input.
4. Инсталирајте струјни трансформатор (CT):
   • Identify the load wire (live wire) of the circuit you wish to monitor.
   • Open the CT clamp and pass only the load wire through the center hole of the CT. Ensure the arrow on the CT points in the direction of current flow (from source to load).
   • Connect the two wires from the CT clamp to the CT input terminals on the meter.
5. Проверите везе: Double-check all wiring connections against the diagram to ensure they are secure and correct.
6. Врати снагу: Once all connections are verified, restore power to the circuit. The meter display should light up.

6. Упутство за употребу

The meter is designed for straightforward operation. Once powered on, it will immediately begin displaying real-time measurements.

6.1. Контрола позадинског осветљења

To control the display backlight:

• Укључи/искључи: Briefly press the button located on the front panel. Each press will toggle the backlight state.
• Уштеда података: The meter automatically saves measurement data regardless of the backlight status.

6.2. Overload Alarm Setting

To set or adjust the current overload alarm threshold:

1. Уђите у режим подешавања: Press and hold the button for approximately 3 seconds until the current alarm threshold value starts flashing on the display.
2. Adjust Threshold: While the value is flashing, briefly press the button to increase the threshold value. The value will cycle through available settings.
3. Сачувај подешавање: Stop pressing the button. After 3 seconds of inactivity, the meter will automatically save the new threshold and exit the setting mode.

When the measured current exceeds the set threshold, the backlight will flash to alert you of an overload condition. The flashing will stop once the current drops below the threshold.

6.3. Energy Data Reset

To clear the accumulated energy consumption (kWh) data:

1. Покрени ресетовање: Press and hold the button for 5 seconds until the energy consumption number starts flashing. Then release the button.
2. Потврдите ресетовање: Briefly press the button again. This action will clear the energy data and stop the flashing.
3. Cancel Reset: If no button operation occurs within 5 seconds after the number starts flashing, the reset will be canceled, and the energy data will remain unchanged.
