20 heinä Adjusting the electrode strap length and tightness
What is the proper length of the belt for me?
Measure you chest size below the pecs/breasts. Adjust the Beat2Phone ECG strap to be significantly shorter than you chest size for tight fit to achieve good electrode skin contact.
80cm chest 65-68 cm strap
100cm chest 72-77cm strap
130cm chest 84-93 cm strap
The strap can be adjusted from 65-93cm to fit chest 78-145cm. Instructions for shortening or lengthening the belt are found below.
How to shorten the strap?
To shorten the strap, pull a loop (A) of the strap through the adjustment clip (B) so that the lenght (L) is decreased. Lock the loop (A) with a safety pin (C) to prevent it from slipping back through the clip (B).
How to lengthen the strap?
To lenghten the strap, take a strip (22cm) of cloth ribbon, fold it in half (A) and attach it to the looped end of the strap with a safety pin. You get a 103cm long strap that extends up to 155 cm. In case more extension is needed, take a longer strip of cloth.
