Chauvin Arnoux E94 [P01120044] 100mA - 100A Power Quality Analyser and Logger Clamp. The Chauvin Arnoux E94 clamp-on current transformer uses a Hall effect cell, which makes it possible to measure direct or alternating current without having to intervene in the equipment to be measured, thus eliminating the need to interrupt the measurement current. The E94 is characterized in particular by its compact, ergonomic shape, thanks to which you can also easily reach places that are difficult to access. Furthermore, the pliers are particularly easy and safe to use. The E94 clamp-on current transformer measures currents from 100 mA to 100 A peak with 2 measuring ranges - 10 A and 100 A. The bandwidth with a continuous frequency range extends up to 100 kHz (-3dB). The E94 has a DC zero pushbutton with setting memory. The output signal cable has a 4-pin sleeved connector compatible with the latest generation of Chauvin-Arnoux Qualistar Class A devices. The clamp is then powered by the device. The device automatically recognizes the clamp-on current transformer via this special connection.
