It's not a test i would carry out with anything plugged in, i would aldo disconnect lamps and Led lights and smoke alarms. It's the only way you'll ever be 100 confident in it results

I wasn't able to examine the shaver TX it had been installed under a floor that had then been laminated. There was no FCU it had been tapped into the RFC.
Apparently the Unit has its own internal fuse but of course if that did blow you need to rip the floor up to replace.
Anyway upshot was low IR readings with it in circuit. Disconnected RFC from both sides of it and the rest of the ring read fine. Had to "assume" the TX has some sort of filtering to earth. Had been working fine for years and worked fine on new RCBO for that RFC and has done since.

I'm having trouble visualizing this. How would you plug your shaver in?

The shaver point on the wall was just passive. The feed to it is the SELV from the TX.
The advantage is the shaver point is small with nothing in it and no in separated mains is fed near it. They aren't very common.
 
IEC leads give false readings then they are faulty.
Agree with faulty , 1x cable reading 300M(500V-unplugged)
probably old ones .
( I was suprised ,thought moulded=Idiot proof ,dirt free )

How do you know it provided an isolated supply.

Pointless exercise unless you get odd readings.
