For some reason, while the weight measurement is in the right area, the body fat has suddenly dropped about 10%. Much as I'd like to believe it's magically true, I know it's not. ;) I've replaced the batteries but am still getting the same readings--correct weight, WAY too low fat measurement with all other measurements (bone, water, muscle) skewed because of it.
Any ideas to troubleshoot it?
Re: Eat Smart scale showing body fat as much too low
Probably there's a build-up of skin oil from your feet that is preventing it from reading properly. Clean off the top of the scale with a cloth dampened in soapy water, then rinse wipe it with a cloth dampened in plain water, and dry it. Be careful not to dribble liquid into the scale.
Note: fat measurement by this method is difficult to do accurately and consistently, For best results, make sure you're properly hydrated at least ten minutes before measuring, and wash and dry the soles of your feet first.

Taylor digital scale, Model # 5721F
Taylor electronic scales are designed to measure your personal weight, as well as your body fat and water weight. Your scale will measure in either pounds or kilograms, indicating your weight to the nearest ounce or gram. You can use the scale as a weight only device or you can take advantage of its bells and whistles by completing the programming process. The scale will store data for up to 10 users. Setup takes only a few minutes.
Set the scale to your choice of kilograms or pounds. The default measurement for the scale is pounds/inches. To change this setting, change the switch on the underside of the scale to kilograms.

This Body Fat. Monitor/Scale passes a low-level electrical signal through the body, which may interfere with the operation of a pacemaker. • The Tanita Body Fat ...
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).
It ispossible that the LOAD CELLS are damaged or there is a fault in the mechanism that is jammed and not reacting to the weight loaded on the tray. So remove and check if this is free and the depression is noticable. If so the LOAD CELL must be replaced.-- hoping that the main control board- processor is OK.
These scales use sensors to measure the electrical resistance of the human body to calculate body fat. If you are not stepping on the scale barefoot then that might be the reason why it is timing out. These scales require you to step on it barefoot so it can take a measurement through your feet. And using the height and gender information in combonation with the resistance measurement it can calculate your approximate body fat precentage. If you are stepping on the scale barefoot then make sure that your feet are properly placed into the sensors and avoid any movement. Let me know if you have any questions.
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.
Digital scales purport to measure your body fat through a process called BIA, or bioelectrical impedance analysis. Essentially, it clocks the speed that electricity travels through you. The scale runs a low-level electric current through your body, using your feet as positive and negative electrodes. The current encounters different levels of impedance, or resistance, from fat versus muscle. The scale measures this impedance, and throws it together with other factors (age, sex, height) to come up with your BMI, or body mass index.
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.
