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
