5. Precauzioni di sicurità

• Stu dispusitivu hè pensatu per solu usu di l'internu. 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.
• Mantene u dispusitivu luntanu da l'acqua, l'umidità è e temperature estreme.
• Ùn pruvate micca di disassemble o mudificà u dispusitivu.

6. Installazione è Wiring

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

Schema di cablaggio

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.

Image 4: Wiring diagram for the KETOTEK DC Voltmeter Ammeter (Model KT-D132). Connect the positive and negative terminals of the DC input to the power supply, and the load in series with the current measurement path.

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. Assicuratevi chì tutte e cunnessione sianu sicure è currette prima di applicà l'alimentazione.

7. Operating Instructions

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.

Funzioni di u buttone

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

• Pressa corta: Toggles the backlight ON/OFF.
• Pressu longu (3 seconde): Resets the accumulated energy (kWh) data. The energy value will flash, then reset to 0.
• Pressu longu (5 seconde): Enters the voltage alarm setting mode.

Voltage Paramètrage d'alarme

Per stabilisce u 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. Se u volu misuratutage falls below the set alarm threshold, the display will flash to indicate a low voltage cundizione.

8. Mantenimentu

• Keep the device clean and dry. Use a soft, dry cloth to wipe the display and casing.
• Evite l'usu di detergenti abrasivi o solventi.
• Mantene u dispusitivu in un locu frescu è seccu quandu ùn hè micca in usu.
• Verificate regularmente i cunnessione di i fili per a tenuta è i segni di usura.

9. Risoluzione di prublemi

• No Display:
  • Check if the DC input voltage is within the 6.5V-100V range. The device requires at least 6.5V to power on.
  • Verificate chì tutti i cunnessione di i fili sianu curretti è sicuri.
  • Ensure the power supply is active.
• Letture incorrette:
  • 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.
  • Verificate per e cunnessione allentate o fili danneggiati.
• 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).
  • Assicuratevi u vulume misuratutage is actually below the set threshold.
