Are you sure you are on DC scale ??
And have you tried adjusting it down to 0.38 ~ 0.4 volt??
I think that it may be user error rather than system error because It would likely not run at that value
I haven't tried to adjust the TPS, as it's almost certainly set correctly and the crazy readings (which I'm sure of by the way, I know my way round electrics and meters, though your point is well made and I would probably have said the same to someone else )
