** So much for RS manuals. The term "peak reading" is a bit
ambiguous in relation to AC ranges on a DMM. Some meters will catch and
hold the highest reading in a period of time.
I think the terms "peak responding" and "average responding" are
I did once see an analogue FET VOM that was definitely peak
reading - good for measuring around inside a TV set.
