ABSTRACT:
A device for evaluating and measuring human sensory perceptions by measuring muscle force applied against a finger button and displaying a maximum muscle force. To obtain an objective measurement, the device according to the invention includes a delay circuit and a display unit. The delay circuit is actuated at the start of a muscle force measurement by a maximum muscle force detector and then the display unit is actuated after a delay of approximately 3 seconds caused by the delay circuit. Preferably, an acoustic signal is provided after the 3 second delay along with a first visual display by the display unit.
