General
Sensitivity	100-10 mV/A

The E27 Insulated AC/DC Current Probe from Chauvin Arnoux is a current clamp designed for use with oscilloscopes, intended for measuring alternating and direct current in electrical circuits. The device enables non-invasive current measurement within a frequency range up to 100 kHz and is rated for maximum currents of 100 Ampere. The current probe is designed for use in electrical installations with voltage categories CAT III up to 600 V and CAT IV up to 300 V, making it suitable for measurements in industrial and commercial environments. The insulation ensures safe operation at high voltages and protects the user from electrical hazards.

Applications

The current probe E27 is particularly suitable for measuring AC and DC current in electrical installations, for example in the maintenance, servicing, and diagnosis of machines, drive systems, lighting installations, or industrial controls. Due to its high frequency bandwidth up to 100 kHz, it is also suitable for analyzing switching operations, pulse width modulation, or transient current waveforms. The combination with an oscilloscope enables the temporal representation of the current waveform, which is advantageous for troubleshooting and performance analysis.

Functions and Equipment in Detail

The current probe features a sensitivity of 100 to 10 mV per 1 Ampere, enabling precise current measurement. The sensitivity can be adjusted according to application and measurement range, with values ranging from 100 mV/A to 10 mV/A. The clamp has an opening with a diameter of 11.8 mm, sufficient to accommodate cables of corresponding diameter. The current probe is powered either by batteries or via an external 5-volt source, enabling flexible use in various environments.

Technology Explained Simply

The current probe operates based on the principle of magnetic induction. When current flows through a conductor cable, it generates a magnetic field, which is detected by the measuring clamp. The probe converts this magnetic field into a proportional electrical signal, which is then transmitted to an oscilloscope. The insulation of the probe protects the user and the measuring device from dangerous voltages. The frequency bandwidth of 100 kHz enables the capture of fast current waveforms, which occur in modern electronic circuits. The current probe is designed for operation in environments with voltage categories CAT III/600 V and CAT IV/300 V, ensuring safe measurement in industrial installations.

Compatibility and Accessories

The current probe is specifically designed for use with oscilloscopes. It features a BNC connector, which is standard on oscilloscopes. The current probe can be connected to various oscilloscopes, provided they have a BNC input. The current probe is not compatible with other measuring instruments such as multimeters or clamp meters, as it was specifically developed for use with oscilloscopes.

Mounting and Installation

The mounting of the current probe is done by simply opening the clamp, inserting the conductor to be measured into the opening, and closing the clamp. The current probe is directly connected to the oscilloscope by inserting the BNC plug into the corresponding input. The current probe requires no additional mounting or installation.

Advantages in Operation

The current probe E27 offers high measurement accuracy and a wide frequency bandwidth, making it suitable for analyzing current waveforms in complex electrical systems. The insulation protects the user and the measuring device from dangerous voltages. The flexible power supply enables use in various environments, whether with batteries or an external voltage source. The combination with an oscilloscope enables detailed analysis of the current waveform in the time domain, which is beneficial for troubleshooting and performance monitoring. The current probe is compact and easy to handle, facilitating measurements in tight or hard-to-reach areas.
