Precauzioni di sicurezza
- Garantire il volume di lavorotage does not exceed DC 30V to prevent damage to the meter.
- Always disconnect power before making any wiring connections.
- Observe correct polarity when connecting the power supply and measurement leads.
- This device is intended for DC circuits only. Do not connect to AC power.
- In caso di dubbi su una qualsiasi fase del cablaggio, consultare un elettricista qualificato.
Caratteristiche del prodotto

Installazione e cablaggio
Proper wiring is essential for accurate and safe operation. Refer to the diagram below for connection details.

Image: Detailed wiring diagram illustrating the connections for the diymore digital voltmeter ammeter. It shows the power supply input (DC 4-30V) for the meter, the voltage measurement input (DC 0-100V), and the current measurement path (0-10A) in series with the load.
Collegamenti elettrici:
- Power Supply for Meter (Thin Wires):
- Red (Thin): Connect to the positive (+) terminal of a DC 4-30V power source.
- Black (Thin): Connect to the negative (-) terminal of the DC 4-30V power source. This also serves as the common ground for the meter's power and voltage misurazione.
Note: The meter's power supply (DC 4-30V) must be within this range. Exceeding 30V will damage the unit.
- Voltage Measurement (Yellow Wire):
- Yellow (Thin): Connect to the positive (+) point of the circuit where you want to measure voltage (DC 0-100V). The black thin wire is the common negative for voltage misurazione.
- Current Measurement (Thick Wires):
- Red (Thick): Connect in series with the positive (+) side of the load.
- Black (Thick): Connect in series with the negative (-) side of the load.
Note: The current measurement wires must be connected in series with the load. Do not connect them directly across the power source. The meter has an integrated shunt for current measurement up to 10A.

Istruzioni per l'uso
Once correctly wired and powered, the diymore Digital Voltmeter Ammeter will automatically display the measured voltage and current on its 0.28" digital tube display.
- The upper display (e.g., Red or Blue) indicates the voltage in Volt (V).
- The lower display (e.g., Blue or Green) indicates the current in Ampere (A).
- The display updates continuously, providing real-time readings.

Manutenzione
- Mantenere il dispositivo pulito e privo di polvere e umidità. Utilizzare un panno morbido e asciutto per la pulizia.
- Evitare di esporre il misuratore a temperature estreme o alla luce solare diretta per periodi prolungati.
- Non tentare di aprire il casing unless you are a qualified technician, as this may void any potential warranty and risk damage to internal components.
- Controllare regolarmente i collegamenti elettrici per assicurarsi che siano saldi e privi di corrosione.
Risoluzione dei problemi
Problemi comuni e soluzioni:
- Nessuna visualizzazione:
- Check the power supply to the meter (thin red and black wires). Ensure it is within the DC 4-30V range and connected with correct polarity.
- Verificare che la fonte di alimentazione sia attiva.
- Volume erratotage Lettura:
- Ensure the thin yellow wire is securely connected to the positive point of the circuit being measured.
- Confirm the black thin wire is connected to the common ground of both the meter's power and the circuit being measured.
- Verify the measured voltage rientra nell'intervallo DC 0-100 V.
- Incorrect Current Reading (or 0.00A):
- Ensure the thick red and black wires are connected correctly in series with the load. Current measurement requires the meter to be part of the circuit path.
- Verify the measured current is within the DC 0-10A range.
- Check for loose connections in the current measurement path.
- Meter Damaged / Burned Out:
- This typically occurs if the meter's power supply (thin red/black wires) exceeded 30V DC. Always ensure the input voltage for the meter's operation is within the specified 4-30V range.
