HTH (Human Touch Hand)
according BSH EMC requirement
The HTH is a device that simulates a real clenched hand with an extended index finger while operating a touch panel. Both the resistance ratios in the static and in the dynamic range were taken into account
The same applies to the formation of the electrical stray field between the clenched hand and the touch panel due to the spherical basic shape of the HTH and its material. The impedance curve corresponds to a real hand up to approx. 1 GHz and is resonance-free!
