ABSTRACT:
Circuitry operative to adjust the reference level of a sensing circuit by varying the energizing input to the sensing circuit inversely with respect to variations in the normal output of the sensing circuit. The adjustment circuit is preferably normally de-energized, and is operative to effect the desired adjustment to the energizing input of the sensing circuit within a fraction of a second after simultaneous energization and reception of a first input signal. The adjustment circuit is further operative upon receiving a second input signal to decrease the energizing input and thereby increase the sensitivity of the sensing circuit.
