The C.A 6417 ground test clamp, supplied in its carrying case, can be used to quickly measure the loop resistances of groundings. Rated for 600 V CAT IV, the C.A 6417 displays contact voltage with a hazardous voltage alarm for added safety during measurements. Ergonomic innovations make it easy to use: a force-compensating system means little effort is required to hold the clamp open, and an OLED display ensures readability from a 180° angle under all brightness conditions. The automatic pre-HOLD mode when the clamp is open and the automatic calibration of the iron gaps when the voltage is applied ensure an optimal evaluation of the values measured with the clamp.Grounding test clamp of ground loops without ground spikes and without opening the disconnection point.
