摘要： To zero or reference-set or null-set a signal source, typically a distance or rotary angle transducer (10), a closed control loop (11, 12, 13) is connected in the output (E) from the signal source, which includes feedback of the system output signal (A) and comparison thereof with a reference or null or zero-set signal (W) when the signal source or transducer is at the reference position, the closed control loop including a correction element (11), such as an adder, to correct the zero or null-set signal derived from the signal source in accordance with the operation of the control loop. This eliminates individual adjustment of the zero or null-set of the signal source, reducing costs and increasing accuracy of the zero or null-set. The correction signal is introduced at the time the signal source or transducer is at a zero or reference position, or the transducer can be preset to provide, initially, a signal which requires correction, and a diode (15) is introduced in the control loop so that the correction signal is effective only in one direction, thus permitting deviation of the transducer from its zero or reference position and not requiring a special switch (14) which renders effective the control loop when the transducer (10) is at the zero or reference position.
