Abstract

The indicator for measurement apparatus with coded numerical output comprises a generator (2) of several audio frequency electrical signals, each of which may be transduced into a distinctive sound using an electro-acoustic transducer and an associated low-frequency amplifier (8). A selector (4) between the generator (2) and the transducer amplifier (8) can be commanded by a logic device (1) in order to provided selectively to the amplifier one of the audio frequency signals. The logic command device (1) searches the different outputs from the electronic measurement apparatus in a pre-established order and sequentially commands the selector according to the coded figures which are successively investigated. A speaker (9) emits a sound sequentially according to the numerical output of the measurement apparatus.
