Hi everyone,
As part of my checking over of the behaviour of the 7081 I ran "mode,testk" and
"nines=8" overnight, the result is a swing larger than I would expect!
max 166.00455
min 166.00040
this means a 25 ppm shift
The circuit is meant to generate a constant current, so if that constant
current can vary by 25ppm over a 20-23 degree house temperature then it is only
accurate to 25ppm for resistance measurement except when used as a transfer
standard.
anyone else find a similar shift?
