Using the Current Probe

The accuracy of current and power readings depends on properly using the 80i-500s Current Probe. The accuracy specifications in this manual assume that the Current Probe is used correctly.

•Always clamp the 80i-500s Current Probe with the arrow pointing toward the load (away from the source) for a phase measurement or toward the source for a neutral measurement. Press Gto verify the Current Probe orientation. If the resulting VA Check Screen generally extends from the lower left to the upper right of the screen, the Current Probe is connected properly.

•Always clamp the Current Probe around a single conductor or parallel conductors that are carrying current for the same phase.

•Always center the conductor in the Current Probe alignment marks.
