Abstract
A voltmeter/phaser includes dual hot-stick probes, each carrying a housing including a digital display, one of the housings also having a measurement circuit for measuring the sensed voltage. A plural-conductor cable interconnects the housings and carries, in two separate conductors, current between the probes and display data between the display circuits, so that identical voltage values are always displayed on the two displays.
