Abstract
An instrument for measuring the equivalent series resistance of a capacitor includes a plurality of constant current generators across which a capacitor under test is adapted to be connected. A selected one of the generators is periodically enabled to supply a constant current to the capacitor and the voltage across the capacitor is measured and displayed a short time after the generator is enabled, after which time the capacitor is discharged and the measuring cycle is repeated.
