The E27 clamp-on ammeter is an isolated current transformer with Hall-Effect technology to represent the shape and amplitude of direct and alternating currents on oscilloscopes.It has two measuring ranges to measure currents up to 100 A with a bandwidth up to 100 kHz.The E27 clamp is powered by batteries independant of the mains supply or with a 5V standard power supply via a µUSB interface, it also has an automatic DC zero point correction and an automatic switch-off when not in use.With its 2 m long connection cable and the insulated BNC connector plug, it can be connected to any oscilloscope with standard connection technology. The clamp-on ammeter can be used in electrical installations of category 600V cat III and 300V cat IV.Currents: 100 mA .. 100 A peakBandwidth 100 kHz (-3 dB)Encapsulation-Ã: 11.8 mmThis text is machine translated.
