IDEAL developed the 770 Series to provide electricians with all the features they need for measuring in 1000A environments and industrial settings. The unique backlit display in the bottom of the clamp is an industry first. It enables an electrician to view measurement results in dark, bright or tight locations without difficulty or safety risk. Electricians have a choice between the 61-772 for testing large AC current, or the 61-774 for AC/DC testing capabilities. Both are True RMS and feature large 2-inch jaws for getting around multiple phase conductors.
