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
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.
