My old old VM1000 which sat in a box for about 6 years is running now 

and showing 15 - 20 deg. F low readings on CHT3.  (Using 160 - 190 deg. 

water to test the with.) I've swapped cables and thermocouples and even 

the socketted multiplexor chips that the thermocouples connect to.  The 

low readings always stay with CHT3.  The same cable connected to a 

different channel works OK.



In talking to what's left of vision micro, the guy seemed to not be too 

disturbed by a 20 deg. error.  A 5 deg. error would certainly not be a 

problem, but I think 20 deg. is getting too big for a parameter that you 

want to see stay below 400 deg.   What kind of accuracy do people 

normally expect in CHT readings?
