Need help to reset BF-542 scale as I have just put 4 new AA batteries in it and do not know where my book is

SOURCE: 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.

Stop buying cheap batteries at Dollar Tree.

Buy ONLY good, fresh, duracell alkalines. I find these to last the longest with any intermittent use but heavy power drain device (like autofocus cameras)

Try and see. Def worth the money.
For freshness, look on the pack for expiry date BEFORE you buy... and get some spares too.

SOURCE: err 4

Sounds like it wasn't initialized, even though it says Er 4 instead of Er 0... According to my manual, to (re)initialize it and reset it to zero, tap the platform lightly. It should show zeroes running across the display for a second or two, then show all zeroes and turn off. It should be re-initialized...

Error Codes for the 5757 (according to my manual):

Er 0 Initialization error (remedy described above)

Er 1 Instability error (step off the scale, then back on)

Er 2 Overload warning (registering weight beyond the 440 pound max)

Er 3 Contact error (body impedance beyond technical limit - try dampening feet and try again for better contact)

Er 4 Bodyfat error (bodyfat percentage is beyond range - try dampening feet and try again for better contact)

Er 5 Bodywater error (bodywater percentage is beyond range - try dampening feet and try again for better contact)

SOURCE: need to reset scale bf-681 tanita scale

I have a tanita body composition scale BC-534. It suddenly stopped working. I have new batteries. Is there a way to reset the digital disolay?
