4. Setup Instructions
Follow these steps to set up your ACCUNIQ BC380 for the first time:
- Unpacking: Carefully remove all components from the packaging. Retain packaging for future transport or storage.
- Placement: Place the main unit on a firm, level, and non-vibrating surface. Ensure there is sufficient space around the device for safe operation and user movement.
- Power Connection: Connect the power adapter to the power input port on the back of the main unit, then plug the adapter into a suitable electrical outlet.
- Initial Power On: Press the power button (usually located on the side or back of the main unit). The display will light up, and the system will perform a self-check.
- Language and Basic Settings: Follow the on-screen prompts to select your preferred language, date, and time settings.
5. Operating Instructions
The ACCUNIQ BC380 is designed for ease of use. Follow these steps to perform a body composition analysis:
- Preparation:
- Ensure your feet are clean and dry.
- Remove any metal objects (jewelry, watches) that might interfere with the measurement.
- For consistent results, it is recommended to measure at the same time of day, ideally in the morning before eating or exercising.
- Start Measurement:
- Step onto the foothold electrodes barefoot. Position your feet correctly on the designated areas.
- Grasp the electrode handles firmly with both hands. The measurement starts automatically without the need to push a button separately once you grab the handles.
- Stand still and maintain a natural posture during the measurement. Avoid talking or moving.

- Measurement Process: The device uses a Tetra-polar electrode method with 8 touch electrodes and operates at multiple frequencies (5, 50, 250 kHz). The measurement takes approximately 30 seconds.
- Results Display: Once the measurement is complete, your results will be displayed on the 7-inch touchscreen. Results are also printed in an easy-to-understand format with measurement comparison to healthy ranges.
6. Understanding Your Results
The ACCUNIQ BC380 provides a comprehensive analysis of your body composition. Key metrics include:
- Body Composition Analysis: Weight, Lean Body Mass, Body Fat Mass, Muscle Mass, Protein Mass, Mineral Mass, Total Body Water.
- Skeletal Muscle / Fat Analysis: Weight, Skeletal Muscle Mass, Body Fat Mass.
- Obesity Analysis: Body Mass Index (BMI), Body Fat Percentage, Degree of Obesity, Abdominal Circumference.
- Abdominal Obesity Analysis: Waist Hip Ratio, Visceral Fat Level, Visceral Fat Area, Visceral Fat Mass.
- Cumulative Body Change Graph: Tracks changes in Weight, Skeletal Muscle Mass, and Body Fat Percentage over time.
