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.
