Hi Ducan

yes i have done quite a bit of google searching ect there was talk of
Qtdmm2 but have not been able to find anything so any how i have bit
the bullet and have started looking at building a plasmoid for it , it
uses a serial interface but that just drives an irled and a diode . the
meter itself is a maplin job but is a dead copy of a named brand so
much so that i would say it is the same thing  with a maplin badge on
.

The ability to connect it to the pc and produce a printed report once
a year was very time saving  

At the moment i cant even remember the name this multi meter went by
( thats what comes of veging in hospital since mid july out mid
September at last) .
