Note: At least one optional current sensor is necessary to measure current or power parameters. To store measurement data, use only the guaranteed SD cards sold by Hioki.

Navigate clamp-on power logger operation with graphical, easy-to-use displays of wiring procedures

The PW3360’s QUICK SET feature is an on-screen guide that walks you through the setup process, right up to starting measurement. Even if you’re unaccustomed to how clamp-on power loggers work, you’ll be able to easily configure and connect the instrument for 3-phase power measurement. In addition, by alerting you to any wiring mistakes, the device’s “wiring check” function serves to prevent measurement errors that are caused by undetected wiring mistakes.

Power logger functionality for displaying measurement results as a graph so you can review them at a glance

The PW3360 displays recorded measured values as a graph for convenient use in power management. In addition to instantaneous measured values, you can review maximum, minimum, and average values by moving the cursor on the demand and trend graph displays.

A portable power logger that’s small enough to use in a confined cubicle

This power logger is an essential tool for power-saving activities. Thanks to a compact design that weighs just 550 g, it’s easy to take into the field and install in confined locations.
