the pulse at rest and during exercise. For the best result of measuring the
pulse at rest, the degree of belt tension should be such that one finger
can be inserted, for a correct measurement of the pulse, the watch should
be above the wrist level at a distance equal to the width of the finger.
For a more accurate measurement of the pulse during movement, it is
necessary to tighten the strap so that the bracelet does not move, do a
warm-up before performing physical exercises.
