The number one most requested accessory for the Fluke 433 and 434 power quality analysers has been a set of low level current clamps to use on secondary transformers.

Fluke has responded to demand from its utility and three-phase customers with the i5PQ3 AC current clamp, which allows Fluke 433 and 434 users to measure from 10mA to 5A.

The Fluke 434 and 433 three-phase power quality analysers firmware upgrade (Version 1.1) has a special calibration setting for the i5s to achieve full accuracy.
