RS PRO Multimeter Current Clamp AC Adapter, 400 A AC, 29 mm This RS PRO multimeter current clamp adapter or transducer is a diagnostic device you can use to measure AC and DC current and convert it to a voltage that can be viewed and measured. The multimeter features clamp jaws, you can open and close around the conductor with no physical contact with the current or need to break electrical circuits. The device offers high specification performance and accuracy. It has a robust, rugged body so you can be sure it will last. Its jaw and trigger are ergonomically designed to ensure the multimeter is easy and comfortable to use. It's supplied with coiled cable output plugs, a carry case and a user manual. The device is subject to electrostatic discharge (ESD) control and complies with electrostatic control standards (ANSI/ESD S20.20:2014 and BS EN 61340-5-1:2007), which means you can rest assured the hazard of electrostatic discharge is reduced.
