5. Configurare și instalare
5.1 Basic Wiring Instruction
The meter requires a 100A/75mV shunt for current measurement. The shunt must be installed in series with the load. The meter itself connects with four wires (not included) to the shunt and the power source.
- Pasul 1: Install the 100A/75mV shunt in series with the DC circuit, between the power source (e.g., battery) and the load. Ensure correct polarity.
- Pasul 2: Connect the meter to the shunt and the power source using four wires. The meter's small wires are for its own power supply and voltage measurement, while the shunt handles the main current. Recommended wire gauge for connections to the meter is 30-12 AWG copper wires.

5.2 Solar System Wiring Instruction
This diagram illustrates wiring for a solar system where an inverter connects directly to the battery. The meter's four wires do not carry large current; they are for measurement and power. Any copper wire from 30 AWG to 12 AWG can be used for these connections.

You do not need to wire both meters if monitoring a solar system; just connect the voltmeter(s) to monitor the specific parameters you require.
6. Instrucțiuni de utilizare
- Pornire: Once correctly wired, the meter will power on and display real-time voltage, current, power, and accumulated energy.
- Controlul luminii de fundal: The backlight can be manually toggled on or off using the button on the front panel.
- Over-threshold Indication: If the active power exceeds a predefined threshold, the backlight and power display will flash to alert the user.
- Energy Data Reset: To reset the accumulated energy (kWh) data, press and hold the button on the front panel for approximately 5 seconds until the energy reading resets to zero.
- Memorie de oprire: The meter automatically saves all settings and accumulated energy data when power is disconnected. This data will be restored upon power-up.
7. Întreținere
- Curățați afișajul și casinȘtergeți cu o cârpă moale și uscată. Nu utilizați substanțe de curățare abrazive sau solvenți.
- Verificați periodic toate conexiunile cablurilor pentru a vă asigura că sunt sigure și fără coroziune.
- Asigurați-vă că mediul de operare se încadrează în intervalele de temperatură și umiditate specificate.
8. Depanare
- Fără afișare:
- Check if the power supply to the meter is connected correctly and within the 6.5-100V DC range.
- Verificați dacă toate conexiunile cablurilor sunt sigure.
- Citiri incorecte:
- Ensure the shunt is correctly installed in series with the load and its connections are tight.
- Check for correct polarity of all connections.
- Verify that the current does not exceed the 100A rating of the shunt and meter.
- Backlight Flashing:
- This indicates that the active power has exceeded the set threshold. This is a normal warning function.
- Energy Data Not Resetting:
- Ensure you are pressing and holding the reset button for at least 5 seconds.
