Getting Accurate ReadingsTo get the most accurate absolute values, readings should be taken without clothing andunder consistent conditions of hydration. If you do not undress, always remove your socksor stockings, and be sure the soles of your feet are clean before stepping on the measuringplatform. Stand erect on the platform.Note: An accurate reading will not be possible if the soles of your feet are not clean, if your knees are bent orif you are in a sitting position.It is best to take readings at the same time of day. Try to wait about three hours after rising,eating, or hard exercise before taking measurements. While readings taken under otherconditions may not have the same absolute values, they are accurate for determining thepercentage of change as long as the readings are taken in a consistent manner. To monitorprogress, compare weight and body fat percentage taken under the same conditions over aperiod of time.Replacing the batteriesWhen the batteries run low, the “Lo” message will appear on the display window.
