Chauvin Arnoux CA 6418 [P01122018] Earth Clamp with Oblong Head.The Chauvin Arnoux CA6418 Earth Clamp Meter can be used to test for earth resistance in installations with multiple earths. The oblong-design of this clamp meter makes it suitable for checking earth cables, earth bars and earth straps, thereby improving the convenience and efficiency of testing. Its clamping capacity facilitates the measurement of cables with diameters of up to 32mm, as well as 30 x 40mm and 20 x 55mm bars; it also enables clamping around earth spikes in restricted spaces. Also improving measurement ease and efficiency is the Chauvin Arnoux CA6418 Earth Clamp Meter’s ability to measure and display earth resistance and leakage current. This instrument is able to measure current between 0.5mA and 20A and features a wide loop resistance measurement range: 0.010Ω to 1200Ω. Additionally, it is possible to configure the Chauvin Arnoux CA6418 Earth Clamp Meter to include leakage current and earth resistance alarms. Measurements can be stored with date and time stamps to the Chauvin Arnoux CA6418 Earth Clamp Meter’s large internal memory. It is possible to save up to three-hundred date and time stamped readings. The inclusion of a real-time clock enables date and time stamping. Measurements are indicated on an OLED display with 180°-visibility, ensuring that results are always easy-to-read despite lighting conditions. Furthermore, the Chauvin Arnoux CA6418 Earth Clamp Meter’s Automatic Pre-Hold function also improves its ease-of-use as it will freeze the latest measurements to the display when the clamp is opened. The Chauvin Arnoux CA6418 Earth Clamp Meter includes other practical features such as automatic calibration of the jaw gap upon start-up, which is designed to optimise the processing of measurements. This ensures that the Chauvin Arnoux CA6418 Earth Clamp Meter is able to determine accurate, repeatable results. Additionally, this clamp meter includes an Automatic Power-Off function which conserves the Chauvin Arnoux CA6418 Earth Clamp Meter’s battery life. The Chauvin Arnoux CA6418 Earth Clamp is supplied with a carry case and CL1 calibration loop. It is an ergonomic, efficient and easy-to-use earth clamp meter suitable for conducting quick earth resistance tests.
