5. Precaucions de seguretat

• Aquest dispositiu està dissenyat per només per a ús interior. Do not use it outdoors.
• Ensure the load does not exceed the rated voltage and current of the device (DC 6.5-100V, 20A).
• Always connect the device according to the provided wiring diagram. Incorrect wiring can lead to product damage or malfunction.
• If you intend to use a different connection method, consult with a qualified professional or contact customer support first.
• Manteniu el dispositiu allunyat de l'aigua, la humitat i les temperatures extremes.
• No intenteu desmuntar o modificar el dispositiu.

6. Instal·lació i cablejat

The KETOTEK DC Voltmeter Ammeter features an integrated shunt, simplifying the wiring process. Follow the diagram below for correct installation.

Esquema de cablejat

Connect the power supply and load as shown in the diagram. The device measures voltage across its input terminals and current through the integrated shunt.

1. Connect the positive terminal of your DC power supply to the '+' (DC input) terminal of the meter.
2. Connect the negative terminal of your DC power supply to the '-' (DC input) terminal of the meter.
3. Connect the positive terminal of your load to the '+' (Load) terminal of the meter.
4. Connect the negative terminal of your load to the '-' (Load) terminal of the meter.
5. Assegureu-vos que totes les connexions estiguin segures i correctes abans d'aplicar l'alimentació.

7. Instruccions de funcionament

The device operates automatically once connected to a DC power source within its specified voltage range. The LCD will display voltage, current, power, and energy simultaneously.

Funcions del botó

The meter features a single button on the right side of the display for various functions:

• Premsa curta: Toggles the backlight ON/OFF.
• Premda llarga (3 segons): Resets the accumulated energy (kWh) data. The energy value will flash, then reset to 0.
• Premda llarga (5 segons): Enters the voltage alarm setting mode.

Voltage Configuració d'alarma

Per configurar el voltage alarm threshold:

1. Press and hold the button for 5 seconds until the voltage value on the display starts flashing. This indicates you are in alarm setting mode.
2. Short press the button to adjust the voltage alarm threshold. Each short press will increment the value.
3. Once the desired threshold is set, press and hold the button again for 3 seconds to save the setting and exit the alarm mode.
4. Si el vol mesurattage falls below the set alarm threshold, the display will flash to indicate a low voltage condició.

8. Manteniment

• Keep the device clean and dry. Use a soft, dry cloth to wipe the display and casing.
• Eviteu utilitzar netejadors abrasius o dissolvents.
• Guardeu el dispositiu en un lloc fresc i sec quan no l'utilitzeu.
• Comproveu regularment les connexions del cablejat per comprovar si estan ben ajustades i si hi ha signes de desgast.

9. Solució De Problemes

• Sense pantalla:
  • Check if the DC input voltage is within the 6.5V-100V range. The device requires at least 6.5V to power on.
  • Verifiqueu que totes les connexions de cablejat siguin correctes i segures.
  • Ensure the power supply is active.
• Lectures incorrectes:
  • Confirm the wiring matches the diagram precisely. Incorrect current path can lead to inaccurate readings.
  • Ensure the load current does not exceed 20A for continuous operation. Overloading can affect accuracy or damage the device.
  • Comproveu si hi ha connexions soltes o cables danyats.
• Energy (kWh) Not Resetting:
  • Ensure you are pressing and holding the button for approximately 3 seconds until the energy value flashes and resets.
• Voltage Alarm Not Working:
  • Verify the alarm threshold is set correctly by entering the alarm setting mode (long press for 5 seconds).
  • Ensure the measured voltage is actually below the set threshold.
