Reading Multiple Thermocouples using Measurement Studio.NET and VB.NET - Value Error

[DieselPower]

I ran my VB.NET program to read two thermocouples.  One value was way off - over 100 C in my office.

Then I used LabVIEW to read the same thermocouples and they were both correct.

I switched back to VB.NET and they were then both correct.

What is the problem?

There should not be any difference between LabVIEW calling your drivers to take a Thermocouple measurement and VB.NET calling your drivers to take a Thermocouple measurement.

Can you reproduce this effect?  Did it just happen that one time?  If you reboot and try it does the problem represent itself?  Was anything touched on the hardware between one run and the next?  Did you have a cold front move thru your test facilities between tests?

Problems like this can usually be traced to something repeatable, so if we can figure out what happened and make it happen again, then we can (hopefully) figure out how to fix it.
