Issue Details

When I run the example NI 9212 getting started.lvproj I read wrong temperature values, even though I connected my input correctly.

Solution

The VIs NI 9212 Convert to Temperature (RAW).vi and NI 9212 Convert to Temperature (Calibrated).vi call the sub-VI NI 9212 Convert Thermistor Reading.vi. To Calculate the correct values, the connected Input (CJCResitance) needs to be connected to the Input called Rt, not Temperature Units.
