HANDS-FREE SIGNAL LEVEL METER

摘要

An electrical signal measurement device comprises sections which are carried by an operator in a belt, jacket, vest, harness (or the like) and a headpiece (10) with a headphone and a visual display (13). The thus wearable system includes speech recognition as well as speech synthesis so the operator may control and communicate with the instrument while his/her hands are left free to perform any necessary function.
