EAV and bioresonance terminology
EAV parabolic electrode
The parabolic electrode is a precise EAV-measuring electrode with a smooth parabolic tip. The shape nestles up against the measurement point and has only a small contact area. This permits a low pressure on the measurement point. Using the parabolic electrode, you can clearly see the EAV plateau effect.
However, due to its pointed form, measurement requires a degree of practice in order to avoid applying too much pressure to rather dry skin. This would be uncomfortable for the person being measured.
