6. Configuració

6.1. Esquema de cablejat

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 és inferior a 8V.

• Connecteu el Shunt in series with the negative terminal of your battery and the negative terminal of your load.
• Connecteu el meter's main power input (red and black wires) to the positive and negative terminals of the battery, respectively.
• Si la bateria voltage is below 8V, an font d'alimentació externa (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. Instruccions de funcionament

7.1. Encès

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. Comprensió de la pantalla

The display provides real-time readings for all 9 measurement functions. The blue backlight ensures readability in various lighting conditions.
