The new Fluke 317 clamp meter is designed based on detailed research into the specific requirements of electrical engineers. The small clamp meter head and lightweight, compact body make it ideal for use in confined spaces. The 40A range low current measurement (0.01A resolution) design is unique and allows users to accurately measure small currents. At the same time, the clamp meter also has functions such as accurate, True RMS measurements, maxi- mum/minimum values, zeroing, background light display, display protection and is a powerful tool in carrying out daily maintenance and instal- lations.
