RE

This page always show the last measured values for line and loop impedance and earth resistance readings, whether manually or auto-measured.

Measurement can be manually initiated by clicking “Measure Now”.

Notes:

"Measure Now" button is disabled for a while before user can measure again to avoid overheating.
In case of one or more events are active, Inspector refuses to measure to maintain inaccuracy, and this is for both periodic and manual measuring.
RE is measured once every 24 hours, at a specific time which is defined by user in Power Configurations page.
