Apropå mätfel, så hittade jag detta på TomToms forum:
chest based straps are an indirect measure, they are measuring electrical impulses, not pulse and are subject to interference from static electricity, sweat, positioning and are very uncomfortable for some people. The wrist based sensor is a direct measure of your pulse (the LED lights are actually measuring blood flow as it passes through the capillaries of the arm).
Så att likadan mätfel dyker upp med båda tekniker är ju lite märkligt...
