Calibration Graphs for Four Thermistors

The adjusted variables for the thermistor temperature formula are shown below each calibration graph.

At the beginning of the run, LabVIEW may write the last temperatures from the previous run to the data file, causing an apparent drop in temperature.

Next Steps

The current LabVIEW program sometimes records a zero or #NV in the temperature data file. We should change the program to so that it replaces a zero or NaN with the previous temperature. If a second zero or NaN occurs immediately after the first, LabVIEW should not replace the second one with another value.
