Loop impedance measurement

Looking forward to learning the results. Don't have another set of leads here or I'd be trying this now.

I think I have some 4mm multimeter leads that can be stacked, will do for a 'careful' test with the pins covered up.

I don't think anyone has asked if either device has been recently calibrated?

#4 mentions it.

I couldn't find the leads, and discovered it won't null out the ~1.1 ohms of my 50m extension lead, but I did find that enabling/disabling the lead zero for low-ohms made no observable difference to the L-N PFC measured (was seeing about 0.21 - 0.22 ohms in all cases)
