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 100 Arms 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 5 V μUSB connector.

1.2. SAFETY

Never make measurements on uninsulated conductors at potentials exceeding 600 V
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 ≤ 2000 m, in an environment of degree of pollution 2.
It can be used for measurements on CAT II installations up to 600 V and CAT III installations up to
300 V 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 @
1 MHz → 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.
