Nastavení a zapojení

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.

Připojení kabeláže:

1. 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 měření.

   Note: The meter's power supply (DC 4-30V) must be within this range. Exceeding 30V will damage the unit.

2. svtage 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 měření.
3. 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.

Návod k obsluze

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 ve voltech (V).
• The lower display (e.g., Blue or Green) indicates the current in Amperes (A).
• The display updates continuously, providing real-time readings.

Údržba

• Udržujte zařízení čisté a bez prachu a vlhkosti. K čištění používejte měkký, suchý hadřík.
• Avoid exposing the meter to extreme temperatures or direct sunlight for prolonged periods.
• Nepokoušejte se otevřít casing unless you are a qualified technician, as this may void any potential warranty and risk damage to internal components.
• Regularly check wiring connections to ensure they are secure and free from corrosion.

Odstraňování problémů

Běžné problémy a řešení:

• Bez displeje:
  • 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.
  • Ověřte, zda je zdroj napájení aktivní.
• Nesprávný svtage čtení:
  • 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 je v rozsahu DC 0-100V.
• 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.
