The extension cable enables the flexible current probes to be extended where the conductors are hard to get to. The iFlex probes connect directly to the 174X Energy or power logger, displaying current measurements without error prone scaling factors. The 1.8 m (6 ft.) cord allows separation between the measurement location and the energy logger making it easier to view the display. Fluke 17XX iFlex cables are available in 12, 24, and 36 inch models.
