Chauvin Arnoux CA6418 Earth Clamp

A helpful tool for determining earth leakage current in electrical installations is the Chauvin Arnoux CA6418 Earth Clamp, which is perfect for adhering to regulation 531:3:2 of the 18th Edition Wiring Regulations. It can detect current between 0.5 mA and 20 mA AC. Moreover, it features a loop resistance measurement capability with readings between 0.01 Ω and 1200 Ω. While loop resistance measurement offers a best accuracy of ±1.5% and a best resolution of 1mΩ, current readings are precise to as little as 50µA and accurate to ±2%. An exceptional characteristic of the Chauvin Arnoux CA6418 is its oblong clamp, which is perfect for measuring earth leakage current in various earth bars. It can clamp round 30 x 40 mm rectangle bars, ø 32 mm cylindrical bars, and 20 x 55 mm rectangular bars. In certain conditions, it can also be clamped at an angle onto an earth bar. An internal memory that holds up to 300 readings that can be retrieved to the screen with a time and date stamp is another feature of the Chauvin Arnoux CA6418. It also has a lighted digital screen. The clamp can be opened to allow for data hold and to automatically freeze readings on the screen. It is possible to configure buzzer alarms for Z and I. Easy to use dial and push-button interface allows you to control the clamp. The instrument may be recalibrated without having to send the clamp back to the manufacturer because the jaw gap is automatically calibrated. The Chauvin Arnoux CA6418 is safety rated as Cat IV 100V and Cat III 150V, and its battery life can last up to 2400 thirty-second readings. Batteries, a wrist strap, a verification certificate, a user's handbook, and a durable carry bag are included. The earth clamp calibration loop, which lets the user examine the clamp's accuracy at 198Ω, 49.5Ω, 22Ω, 12.4Ω, and 7.9Ω, is a really helpful extra accessory.
