Thank you for all of your replies.

I only have a multimeter and a basic one at that (TIS 258), I'll have a
look online to see if that is of any use, otherwise I'll go about
getting power socket meter as it'll be useful to have anyway.

It's got a 10A scale, but only dc. A bridge rectifier would enable it to
measure Henry's current draw. Realise that it'll only handle 10A for a
few seconds.

Don't see any such limitation on mine.


photos of the TIS 258* show it having the same warning as on an
apparently identical (but differently badged) cheap mm I have - ie the
10A inputs labelled "max 30 secs every 15 min"

Multimeter high current scales are normally that way. How long it can cope for depends on meter quality, or is one of the qualities of a meter. 30s isn't bad.
