Measuring instrument having two pairs of lines connected to two indentical pairs of terminals, via which signal current flows through one pair and supply current flows through the other pair
First Claim
1. Measuring instrument to be connected to a higher-order unit having at least a first and an identical second pair of terminals, comprising:
- a first first pair of lines, to be connected to the first pair of terminals, via which a signal current flows during operation, the signal current being a measure of an instantaneous measured value, and a second second pair of lines, to be connected to the second pair of terminals, via which a supply current flows during operation, whose value is greater than or equal to a minimum signal current and less than or equal to a maximum signal current.

Abstract
A description is given of a measuring instrument to be connected to a higher-order unit (57, 75) having at least a first and an identical second pair of terminals, which can be connected electrically, very simply and without errors, to the higher-order unit, the measuring instrument (61) comprising:
a first pair of lines (1), to be connected to the first pair of terminals, via which a signal current flows during operation, the signal current being a measure of an instantaneous measured value, and a second pair of lines (3), to be connected to the second pair of terminals, via which a supply current flows during operation, whose value is greater than or equal to a minimum signal current and less than or equal to a maximum signal current.
