We continue to publish the materials of the “Physiokey is not SCENAR” series. Fig. 1 shows the motherboard of the Physiokey device, and Fig. 2 shows the block of this motherboard which forms the treatment pulse.

You can clearly see that there are no elements for the block’s tuning on the board. For the required tuning level it is important that the tuning is done after all the elements are installed to the board. That allows to exclude the influence of the elements’ parameter spread on the pulse’s shape and sensitivity to changes in the skin impedance. The inability to perform such tuning does not allow adjusting the Physiokey device the same way as SCENAR. Thus, Physiokey is not SCENAR.
