single-point calibration with thermocouples in SignalExpress?

[JoshB]

I have a USB-6251 DAQ that I'm using with SignalExpress to measure some J-type thermocouples.  I'm looking to calibrate them, but it appears that I have to do a multi-point (>2 points) calibration.

Since the range that I care about is relatively close to 0C and I'm not too worried about a super-precise calibration, I'd just like to do a simple single-point calibration in an ice bath to remove the offset error.  Is this possible?  When I use the calibrate wizard in SignalExpress, it requires at least two points.

Furthermore, it appears that it won't extrapolate beyond those two points, so even if I just use an ice bath and a bath of water at room temperature (taking the calibration value from another digital thermometer that has been calibrated), it will clip the values to that range.  Very unhelpful.  Can I get around this?

Thanks,

Josh

Yep, a dupe.  I posted here first, then realized it was the wrong place.  If there was a way to delete my own post here, I would happily do it.
