How to Use the Hioki Digital Phase Detector PD3259-50

In the past, four steps have been necessary in order to check a 3-phase power circuit: one set of measurements to check the phases with a phase detector, and three line-voltage measurements (one for each phase) made with a tester. The Digital Phase Detector PD3259-50 replaces this process with a single, no-metal-contact measurement step that can be made simply by affixing three clamp sensors. The instrument quickly displays the phase detection results and three phase voltage values.
