1.1. Presentation

The clamp is an oscilloscope current probe using a Hall effect cell, allowing the
measurement of direct or alternating currents up to 100Arms without intervention on
the electrical installation (cutting off of the current to be measured). It is a transducer
delivering a voltage output.
This ammeter clamp, with a round core and air gap, allows rapid measurements of
current in conductors; the measurement output is completely insulated from the
conductor. Its user-friendly shape and small size are especially well suited to this
type of measurement.
Its measurement sensitivity, its metrological performance, and its very good
frequency response qualify it as an oscilloscope accessory.
The connection is made by a BNC coaxial cable.
The clamp is powered by an internal storage battery and by a standard type B 5V
µUSB connector.

1.2. Safety


Never make measurements on uninsulated conductors at potentials
exceeding 600V with respect to earth.
This clamp is protected by double insulation or reinforced insulation. It does not need to
be connected to a protective earth to ensure electrical safety. The USB power
connector is isolated from the measurement output, preventing any hazardous potential
from the BNC connector.
It is designed for indoor use, altitude ≤2000m, in an environment of degree of
pollution 2.
It can be used for measurements on CAT II installations up to 600V and CAT III installations
up to 300V and complies with international standards IEC 61010-1 and IEC 61010-2-032.
Do not use it on conductors carrying currents at high frequency, greater than
4 Arms@1MHz  risk of burns and of deformation of the jaws of the clamp.
The protection provided by this clamp may be impaired if it is used other than as
specified.
