6. Nastavení

6.1. Schéma zapojení

Follow the wiring diagram carefully to connect the meter and shunt to your DC power system. Ensure all connections are correct and secure.

Image: Detailed wiring diagram showing connections for the KETOTEK KT-D288 meter, 100A shunt, battery (DC 0-200V), and load. An external power supply (3.3-12V) is indicated for use when the battery voltage je nižší než 8V.

• Připojte Shunt in series with the negative terminal of your battery and the negative terminal of your load.
• Připojte meter's main power input (red and black wires) to the positive and negative terminals of the battery, respectively.
• Pokud je baterie objtage is below 8V, an externí napájení (3.3-12V DC) is required for the meter. Connect it to the designated external power supply terminals.
• Ensure the current range is correctly set (0-20A or 0-100A, 100A is default).

6.2. Screw-less Terminal Installation

The meter features push-on terminals for easy wire installation.

• To insert a wire, gently press the corresponding terminal button.
• Insert the stripped end of the wire into the opening.
• Release the button to secure the wire.
• To remove a wire, press the button again and pull the wire out.

7. Návod k obsluze

7.1. Zapnutí

Once correctly wired, the meter will power on automatically when DC voltage is applied. The LCD display will illuminate, showing the current measurement parameters.

7.2. Pochopení displeje
