Body Composition Weight Analysis Tool

Body Composition Module Weight Function Analysis

Paste body-weight ADC values together with actual test weights. The points do not have to be fixed at 50kg, 100kg, or 150kg; the tool first checks the measured range, then uses recommended calibration points as high-weight references.

Step 1

Test data preparation

Confirm the ADC source, repeated sample count, and weight coverage before entering data.

1

Use decimal ADC values from the reading described in the module specification.

2

For each weight, read at least three samples after the scale is static.

3

Wider weight coverage makes the high-weight reference conclusion more reliable.

Step 2

Input Test Data

Each row format: actual weight kg, ADC. Multiple ADC values can be placed on the same row.

Example: 10, 201, 198, 205 means three ADC samples at 10kg. Commas, tabs, and spaces are supported; header rows are ignored.

Coverage is calculated against the recommended 0/50/100/150kg calibration range; uncovered high-weight sections are trend references only.

    Data Detail

    Review the linearity chart, data table, and calibration reference.

    Linearity

    Light dots are individual raw ADC samples, solid dots are per-weight averages, the blue line is the average-based linear fit, and gray dashed lines are recommended reference weights.

    Calibration

    Target kg Reference ADC Source Adjacent signal Judgment
    Against the recommended 0/50/100/150kg calibration points, BMH05104-2 needs at least 20,000 ADC per adjacent 50kg segment; BMH05108/BMH05109 need at least 32,000 ADC per segment. Non-recommended weight points can still be used for linearity and stability checks.
    This tool is for body-composition module weight-function self-checks based only on the entered ADC data. It does not replace final metrology certification or quality judgment.
