When you do a L&N-E IR test, is there anything (other than a fault) that could be left plugged in that would produce a low reading?

I'm not asking for a particular scenario, like I'm not having issues. Just wondering if there's any predicament that could cause a L&N-E IR test to cause a low reading and stick that knowledge in the back of my head somewhere.surge protection?
IT equipment. computers are renown for having small earth leakage.typically around 3mA apiece. that's why you never put too many on a circuit with RCD protection.
Its a handy method for EICRs when you either cant disconnect everything, or are unsure of any loads that are connected without your knowledge.
IT equipment should not give false readings unless they incorporate filters and this is rare. IEC leads should never give false readings. Testing an office last night nothing unplugged all circuits above 100 meg. Shaver socket is a new one on me and I think you need to ask if such things and IEC leads give false readings then they are faulty.( Is it a reason to start splitting ring up ... or is that cheating )
Localise !
Never mind IT equipment plenty of naff IEC cables out there !
(IEC leads may test good at 120V for some reason ...)
