Subject: speech response for measurable physical quantities of digital multimeters. The invention relates to an audio speech response produced out of the digital visual indication of the digital multimeters. It utilizes an electronic circuit translating the signals of the digital screen of the classic multimeters into sound speech corresponding to the digital number of the LC or LED screen. During the measurement of a physical quantity (e.g. voltage), the visual contact of the user of the twoterminals is not detached so that potential short circuit or false measurement may be avoided. |
