Like all body fat tests, body fat scales don't actually measure your body fat percentage. They determine your body density. The examiner (or the scales) then uses a formula to calculate body fat percentage based on body density. These formulas just predict your body fat. Unfortunately there is no one formula that accurately predicts body fat for the whole population. Differences in age, gender, ethnicity, body size, and fitness level all have a significant affect on the results. Well, whether body fat scales measure your "true" body fat percentage or not doesn't matter! As long as they can accurately monitor changes in your body composition over time, that's all you need.

How do I obtain the bone,muscle,hydration,fat and calorie measurement on a dquip body fat/hydration monitor scale (infrared transmission body fat scale) I see the weight on the scale Bella

These measurements are based on BIA (bioelectrical impedance analysis). As you stand on the scale, you stand on electrodes, which generate small electric impulses which pass throughout your body (and different tissues of course). Different tissues have different electrical conductivity and resistivity due to their different hydration (e.g fat tissue contains very small % of water, that's why its resistance is high), so the scale measures the % of different tissues in your body by analyzing the resistance(this analysis is quite complicated and not very accurate).

What does Err3 mean on taylor body fat scale?

Remove your shoes and socks and wet your feet slightly with a damp cloth if you receive the "ERR3" error. ERR3 is a contact error and your feet should ideally be bare and wet to achieve an accurate body-fat reading.
  • Step off the scale and wait for it reset. Remove your shoes and socks and wet your feet slightly if you receive either the "ERR4" or "ERR5" errors, which means your body-fat or body measurements are out of range.
  • Reset the scale if it doesn't work or you continue to receive error messages. Remove the battery and set the scale on a flat surface. Stand still on the scale for five seconds and step off. Re-install the battery and place the scale back on the flat surface. Place one foot on the scale until it displays zeros or dashes. Remove your foot and wait for the scale to turn off. Step back on the scale to weigh yourself

    My weight is not accurate. I weigh 260+ and the scale reads 245 to 249 and is inconsistant. I just replaced batteries (CR2032)for the second time

    Very few electronic scales are accurate as they are a function of a resistance measured against a voltage. They may be accurate when you buy them, but over time the electronic components decay and read differently as the components are cheap 10% type resistors and capacitors and cannot hold their specific values over time.
    If you want accuracy, you will have to get a balance type scale that can be calibrated on site.

    BF% is wrong

    Unfortunately, it's the scale, but it's not broken. It simply is telling you inaccurate information.
    Some scales utilize Bioelectrical Impedance Analysis (BIA) technology. BIA uses very low levels of electrical impulses running from one metal contact point/lead to another. Your body acts as the connector between the two contact points, thus completing the circuit. Not all scales use this means for calculating body fat percentage due to poor reliability and high fabrication costs.This method of measurement requires very large contact points, as well as clean and moist skin exposure. If you have dry/calluced feet, which is normal for most Americans, the sensors can not accurately measure due to skin resistance. Dry skin acts as a resistor to electrical impulse. Electricity passes through muscle and fat at different rates. However, its measurements may be thrown off by how hydrated you are and how much you've eaten; it may be too inaccurate for anything other than comparative use. Users are encouraged to establish a baseline measurement and repeat measurements under consistent conditions over time to detect changes.
    Many less expensive models simply use a body-fat calculator to average your imputed height in inches, waist measurement in inches and the current weight measurement recorded in lbs. The scale compares your measurement with the ideal norms inputed during the manufactoring process, thus giving you a comparison vs.imputed norms. People who are very, very fit can get numbers 3 to 5 percent higher than their true percent body fat. Because they don't have a lot of fat inside their muscles(visceral fat), the simple tape measure calculation test cannot adjust as it should indicate.
    Conversely, if a person is skinny but not fit, this body fat test may yield a number 3 to 5 percent lower than his or her true percent body fat. Though they look thin, unfit skinny people really have more than the usual amount of fat inside their muscles, which you can't see from the outside.
    In either case, the scale is not necessary a measurement tool, due to high variables of test inaccuracy and interuser reliabilty; but, it is a good tool for comparing whether or not you are gaining/losing body fat.
    If you would like a more accurate tool for simply measuring your body fat, you can pick up some pinch-calipers online for about the price of a scale. They come with an instructional pamphlet, very easy to use.
