Abstract

A signal cable (1) is connected to a heat camera video outlet, and a further cable (2) is coupled to a picture screen video input. The signal cable carries a signal voltage from the camera in the form of a video signal (Uv) fed partly to an isotherm level value producer (3), partly to an isotherm generator (4) with three inputs, and partly to a changeover point (5) from which the further cable feeds. The changeover process at the point is controlled by a signal deviating from the video signal (Uv) so that an isotherm marking is obtained when it is connected. The isotherm level value producer output is connected to the one input of the isotherm generator. The signal cable is coupled to the second input of the isotherm generator the output of which is connected (7) to the changeover point. To the isotherm generator third input is fed a signal voltage (delta U), and the isotherm level value producer produces a reference level signal (U ref) from the video signal (Uv). Out of the signals (Uv, U ref and delta U), the isotherm generator produces an isotherm signal (U iso) which takes the value of 0 or logical 1. @(Provisional basic advised week 92/01)@ @(12pp Dwg.No.1/3)@.
