Hioki’s non-contact voltage detection and measurement technology places efficiency and safety as priority considerations with the goal of protecting customers that need to conduct on-site electrical work as part of renovations and expansions of manufacturing plants and buildings. The PD3259 Digital Phase Detector lets you to measure three-phase voltage and detect phase sequence simultaneously by just clipping onto covered cables, ensuring absolutely no contact with metal parts for maximum safety. CAT IV 600 V Recipient of the Good Design Award 2016 Key Features Note: Only the voltage value is displayed when measuring a single-phase/3-wire circuit. |

How to Use the Hioki Digital Phase Detector PD3259 How to Use the Hioki Digital Phase Detector PD3259 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 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. *This video depicts measurement of a 3-phase power circuit in Japan. The instrument can also be used to measure power circuits in other countries, for example 3-phase/4-wire circuits. |

Phase detector + tester functionality: At-a-glance, no-metal-contact phase detection and line voltage measurement in 3-phase circuits With the PD3259, you can check both phase order and line voltages simply by clipping the sensors to the outside of the circuit’s insulated wires. |
 |
Simultaneous display of phase order, ground phase, and 3-phase voltage values Phase order, ground phase, and 3-phase voltage values are displayed at the same time on a large, easy-to-see display that can be used as-is to create photographs to document electrical installations. |

Easy-to-understand visual and aural communication of judgment results The PD3259 indicates phase order (normal/reversed) judgment results via the color of its backlight and a beeping sound. [Normal phase order] [Reversed phase order] |
