Abstract

These measuring systems are, for example, those in anaesthetic and therapeutic breathing apparatus and monitors, in which the measurement values can be output continuously or intermittently. It is the aim and object to compensate for a false signal produced by parameter effects, which causes a zero-point deviation. This is essentially achieved by means of an inverting and a non-inverting circuit arm which is connected or disconnected by means of an electronic switch or makes it possible to store a difference voltage (zero-point deviation) in order to utilise it for the correction.
