Abstract
A measuring instrument capable of providing its readouts of measurements of a physical quantity such as voltage, current or resistance includes voice synthesizer circuitry which may be realized by the use of a large scale integrated circuit (LSI) chip. A mode selector switch is provided for selection of an audible indication mode and a visual indication mode.
Claims8
A measuring instrument comprising:
- means for measuring and quantizing data to form a measured value signal;
- first digital semiconductor memory means for storing digital representation of words to be used in audibly reciting measured values;
- second digital semiconductor memory means for storing digital representations of units of measurements used in said measuring instrument;
- selection means responsive to said measured value signal for selecting areas within said first memory means corresponding to the digital representation of words to be used in audibly reciting said measured value and for selecting areas within said second memory means corresponding to the digital representations of words to be used in audibly reciting the units of measurement used;
- means for decoding said digital representations produced by said selection means to produce an analog audio synthesized speech signal;
- transducer means for converting said audio signal into an audible representation of said measured value and the corresponding units of measurement used;
- and
- means for providing an audible warning signal immediately before the delivery of the audible representation of said measured value.
