5. Setup and Installation
Proper installation is crucial for accurate measurements and safe operation. Follow the wiring diagram carefully.
- Connect the Hall Sensor: Install the Hall sensor in series with the main DC power line between your battery and the load/charger. Ensure the arrow on the Hall sensor points in the direction of current flow from the battery to the load, or from the charger to the battery during charging.
- Connect Sensor to Display: Use the provided 50cm data transfer cable to connect the Hall sensor to the display unit.
- Power the Display Unit: Connect the 50cm H2.54 red/black power cable to the display unit. Connect the red wire to the positive (+) terminal of your battery (or a separate power source within the 8-120V range) and the black wire to the negative (-) terminal.
- Verify Connections: Double-check all connections to ensure they are secure and correctly polarized before applying power.
