Abstract
An electronic measuring instrument measures and records power disturbances and other power parameters on an alternating current system. The instrument incorporates a speech synthesis subsystem, coupled to a telephone system, which is capable of providing a spoken report describing power disturbances and other power parameters. The telephone coupling system incorporates a structure for sharing a telephone extension in a non-disruptive way.
