The E27 clamp is an insulated current sensor using Hall-effect technology to view the waveform and amplitude of DC and AC currents.

It offers 2 sensitivities for measuring currents up to 100 A with a 100 kHz bandwidth.
The E27 clamp is powered by battery or by a standard 5 V DC mains adapter via its ?USB interface and offers automatic DC Zero adjustment and an automatic power-off function.
Its coaxial cable 2 meters long and its insulated male BNC plug allow connection to any oscilloscope equipped with standard connection technology. It can be used to work on 600V CAT III and 300V CAT IV installations.
