Daily Measurement

With original SENSE ON patent technology, BF-1256-B1 

will automatically switch on as you step on the platform 

barefooted. 

According to the analysis results, the 

system will automatically identify the 

possible User ID with most similar 

history records. Then the measuring 

results will be displayed sequentially 

three times.

When the system finds out two or more users with 

similar history records, it will notify you to choose 

between, for example, P1 and P2. You may press  

    key for P1 and or     key for P2. The measuring 

results will then be sorted into the User ID you 

selected and displayed sequentially three times.

Stand still and keep full contact with the 

electrodes until the LCD stops displaying

moving “o”. 

Body Fat Indicator

The Progress Bar at the top of the LCD Display also 

functions as the indicator of body fat level. When 

the measuring result is displayed after analysis, the 

varying length of the bar indicates different levels of 

body fat.
(

Please refer to Table of Body Fat Level for more 

details.
