Abstract A device for providing a visual indication of the value of a variable of an electrical signal comprises a plurality, n, of driver circuits each having an input terminal for receiving the electri- cal signal and a plurality, n, of output terminals. Each driver circuit is operable in a mode in which it provides an output signal at its ith output terminal when the value of the variable lies in a range corresponding to the ith increment on a scale of m increments. The position of the scale of m increments associated with each circuit is adjusta- ble so that the scale of m increment associated with the jth driver circuit overlaps by ((m - 1) + (n - l/n) increments the scale of m increments as- sociated with at least one of the (j - 1)th circuit and the (1 + 1)th circuit. Light emitting ele- ments, arranged in a linear array, are coupled to respective output terminals of the driver circuits.
