ABSTRACT:
A self calibrating electronic instrument for measuring a physical quantity. The instrument generates an internal correction signal that forces its output to zero whenever it is determined that no physical quantity is present for measurement. The correction signal so generated is preserved and continuously applied as a correction signal during intervals when measurements are being performed.
