Winchill On Graph is Wrong

The windchill line on the WD graph is wrong, every few minutes it read as 1900+ C.

Any suggestions why it is doing that?
Thanks,

you need to decrease the bottom range of the graph
go to setup, graph setup, then click on down for lift/ lower the temperature

(what is happening is its go out of range)

i need to make this more automatic detected…
