I want to accurately measure single-phase and three-phase test objects. The test set may be connected to a single-phase or three-phase power source (depending on which test bay I'm in). The information for 6250/6260 says that all three inputs are needed. When I switch over to single-phase measurement (e.g. single-phase test object), will I need to switch over to a single-element transducer such as the 6220 (which measures with one element)?
