Adjusting The Percent Body Fat Reading

The FUTREX-5500A/WL has been carefully calibrated to provide body fat estimations. The calibration is traceable to the generally accepted hydrostatic procedure.

1)Turn unit on.

2)During countdown press CLEAR, SELECT PROGRAM, RISKS.

3)The Digital display will read “A1”

Press ENTER

4)The digital display will show the value of the optical standard.

5)If no change to the calibration is desired - press CLEAR.

6)If you wish to change the calibration:

Press SELECT PROGRAM, then press RISKS. The display will show “0.0” (if no calibration adjustment has been made) or the previously entered adjustment value.

Press the numbered key to enter the amount of adjustment. For example, if you want to decrease the instrument’s

estimates by 1.0% - press 1, press 0, then the minus sign, and then ENTER. All future body fat estimates will now read 1.0% lower.

8)Once the correct offset has been entered into the unit, press ENTER. The adjusted optical standard value will be displayed.
