sensors. The HHM800 Series is lightweight and does not use magnetic cores like standard transformers.

The transformation principle is based on an air core. It presents virtually no load to the system under test, has low phase shift and excellent frequency response and cannot be damaged by current overloads. The sensor assembly is waterproof and insulated for 1000 V working voltage. The HHM800 Series has an mV output proportional to the current measured for direct readings on DMM’s, loggers, oscilloscopes and power or harmonic meters. The length of the flexible sensor can be selected from 610 mm (24") to 1520 mm (60").

The HHM800 Series flexible ac current probes are composed of a flexible sensor and an electronic module. The flexible sensor permits measurements on conductors where standard clamp-on probes cannot be used.

In particular, it can be installed in tight spaces, around cable bundles, around wide or large bus bars or even wrapped around irregularly shaped objects. Probe design enables the user to pre-shape the sensor before inserting it between or around conductors. This feature facilitates positioning the sensor around the conductor, enhances user safety and alleviates the drooping effect associated with other flexible
