How do i calibrate my welby fat monitor scales

SOURCE: Body Fat Reading Changing Drastically

The fact of matter is those devices are inacurate for some reason more so on smaller females. But if you recently took a bath or drank water it will alter the results, they suggest taking it first thing before bath or eating in the morning at same time everyday to get a more acurate reading.

This may be getting personal but implants will also affect the reading making it totally useless for you to use. I have them and the electrical impedence devices read me much higher then what i am, a few minutes later will read me lower.

I would head down to your gym most of them will do a free body fat test with the calipers which is more acurate (as long as they know what they are doing).

mcdevito75 here, There should be a button or knob fairly clos eto the weight indicator to re-set or put the scale back to zero.
