3. Setup Instructions

3.1. Installation

1. Prepare Mounting Location: Choose a suitable location for the monitor. The installation dimension is 58.5x28.5mm. Ensure adequate space behind the panel for wiring.
2. Cut Opening: Carefully cut an opening of 58.5mm x 28.5mm in the chosen panel using appropriate tools.
3. Insert Monitor: Insert the DROK Battery Monitor into the cut opening.
4. Secure Monitor: Secure the monitor in place using the provided mounting mechanism or clips (if applicable).

3.2. Wiring

The monitor typically uses a two-wire connection for power and voltage sensing.

• Red Wire: Connect the red wire to the positive (+) terminal of the battery or power source.
• Black Wire: Connect the black wire to the negative (-) terminal of the battery or power source.

Ensure connections are secure and observe reverse polarity protection. Incorrect wiring can damage the device, although the monitor has built-in protection.

3.3. Voltage Calibration

For optimal accuracy, the monitor features a voltage calibration potentiometer.

1. Locate Potentiometer: Remove the soft plug from the back of the monitor to access the voltage calibration potentiometer.
2. Adjust Voltage: Using a small screwdriver, gently rotate the potentiometer to adjust the displayed voltage to match a known accurate voltage reading from a multimeter.
3. Replace Plug: Once calibrated, replace the soft plug to maintain the waterproof seal.

4. Operating Instructions

4.1. Powering On/Off

• Power On: Once correctly wired, the monitor will power on automatically and display the battery status.
• Power Off: Disconnect the power supply to turn off the monitor. The device has low power consumption when idle.

4.2. Display Interpretation

The LCD screen simultaneously displays three key parameters:

• Voltage (V): Shows the current battery voltage.
• Capacity Bar: A graphical representation of the remaining battery capacity.
• Percentage (%): Displays the remaining battery capacity as a percentage.

4.3. Setting Key (SET)

The "SET" button is used for configuration. Specific functions may vary based on firmware version. Refer to the detailed programming instructions for advanced settings, such as battery type selection or low voltage alarm thresholds. (Note: Detailed programming instructions are not provided in the product description and may require consulting the manufacturer's website or a separate guide.)

5. Maintenance

• Cleaning: Wipe the display and casing with a soft, damp cloth. Avoid abrasive cleaners or solvents.
• Waterproof Protection: The monitor is waterproof. However, ensure the back soft plug for calibration is securely in place to maintain its waterproof integrity, especially in marine or outdoor environments.
• Connection Check: Periodically inspect wiring connections for corrosion or looseness to ensure stable transmission and accurate readings.
• Storage: If storing the device for an extended period, disconnect it from the battery.
