5. Setup and Installation
Follow these steps for proper installation of the battery voltage meter:
- Mounting: The meter has a size of approximately 47x27x16mm (1.9x1.1x0.6in) and a mounting hole size of approximately 45.5x26.5mm (1.8x1.0in). Ensure you have an appropriate cutout for flush mounting.
- Wiring:
- Connect the red wire to the positive (+) terminal of the battery or power source.
- Connect the black wire to the negative (-) terminal of the battery or power source.
- Ensure connections are secure and insulated to prevent short circuits.
- Battery Type Selection: Refer to the labels on the back of the meter (Figure 4.3) to select the correct battery type and voltage range using the internal switches. Options typically include 12V, 24V, 48V, 60V, 72V, 96V for Lithium or Lead-Acid batteries. Incorrect selection may lead to inaccurate readings.
- Power On: Once wired correctly, the meter will power on and display the current voltage and battery capacity.

6. Operating Instructions
The Garosa Battery Voltage Meter operates automatically once connected to a power source within its specified voltage range.
- Display Modes: The meter typically cycles between displaying the current voltage (V) and the battery capacity percentage (%). Some models may have a button on the side (refer to Figure 6.1) to manually switch between these display modes or to adjust settings.
- Reading the Display:
- The large digital numbers indicate the voltage or percentage.
- The battery icon graphically represents the charge level, with green segments indicating remaining capacity and red indicating depleted capacity.
- Monitoring: Continuously monitor the display to keep track of your battery's charge status and voltage. This helps in preventing over-discharge or over-charge, extending battery life.
