Abstract
An automatic monitoring system for the constant current source in a balance having electromagnetic load compensation includes circuitry which generates a first current varying in dependence on the constant current and furnishes a digital signal indicative of the value of that current. A microcomputer is provided to compare the digital value to a reference value. If the comparison indicates that the constant current is outside of a given range of values, the microcomputer energizes the display to indicate the presence of an error.
