First, step on the scale and once you are in position, grab the measuring bar firmly with both hands. The palms of your hands have to make contact with the electrodes on the bar. It is recommended that you remove bracelets or rings that could hinder readings.
When you have the bar in your hands, pull it towards your waist and then separate your arms from the trunk, moving them forward. It is not necessary to lift them more and do not exceed shoulder height since, if you perform an incorrect manipulation on your part and pull the cable to the end of the route with force, you could get to block the reel, preventing it from collecting itself.
