Multi-probe metering apparatus
First Claim
1. Multi-probe metering apparatus for measuring electrical magnitude or magnitudes associated with electrical magnitudes and for displaying the results or for transmitting them to users, the apparatus being characterised by a modular structure consisting of a central unit (I) comprising an input signal acquisition circuit providing signals for a memory processing circuit (1, 2, 3) supplying the display means and signal output means for users (19, 24) of at least one detachable module (II) establishing a link between the central unit (I) and a pick-up or pick-ups (III), the said module (II) being associated with one or a plurality of specific pick-ups (III), the said module (II) being itself connected (4, 9, 10) to the central unit (1) by electrical connections which are established at the same time as the mechanical connection is made between the module (II) and the central unit (I), each module (II) comprising processing circuits (15) linked to the pick-ups (III) which the module (II) is capable of accepting, and means (16, gate A, gate B) supplying the central unit (I) with information to identify the pick-up or pick-ups (III) with which the module (II) is associated in order to control within the central unit (I) the corresponding treatment of the signals provided by the pick-up(s) (III), each module having two input gates connected by two distinct routes to the central unit which receives and processes separately and independently the signals emanating from the two routes, after which it combines them.

Abstract
A multi-probe metering apparatus is characterized by a central unit (I) comprising various signal processing circuits and modules (II) having two gates (A, B) to which are connected various pick-ups (III). The central unit (I) communicates with the module (II) via a numerical signal link (10) for the transmission of pick-up identification signals, and by two analogue links (9, 9b) permitting simultaneous connection of two pick-ups.
