Kent working back out there yet again
I have only ever done this test at an hospital and then I was only observing but if my memory isn't failing me I think it was done with a normal insulation resistance tester

For a normal LV installation Ithink you set the meter to 500volt for HV you set it to 1000, as I recall.But I can't for the life of me remember what values you should be expecting

Similar tests using the same test equipment are required for both conductive and non-conductive flooring. At one time UK Hospital operating theaters had non-conductive flooring, but these day's it 's conductive flooring to meet the IT derived PA/PE earthing requirements.
