"R" must be scaled to kOhms

[Tadinho]

How i could change it? What kind of units it is by default?

I can see that lil red dot where R wire goes to compound is it the case ?

Thanks.

Seriously?  That little red dot is there to let you know the value of AI0 is being coreced to DBL (I'm assuming from SGL).  I would have absolutly no way of knowing what hardware you have attached to node two AI0 but I bet you can apply a scale to the task.

Ye labview is new to me.I have started thread on WSN forums to get things clear with hardware and all wiring.

Its a fairly straightforward equasion:

WARNING, the above vi snippet has a subtle bug in it.  I have fixed the bug and now reattach the correct snippet.

The formula implemented incorrectly was 

T = [K0 + K1(ln R) + (K2 x ln R)^3]^(-1) – 273.15

rather than:

T = [K0 + K1(ln R) + K2x(ln R)^3]^(-1) – 273.15
