Mayo,
For a more general purpose answer as to using LabVIEW for monitoring C type Thermocouples, consider posting in the DAQ or LabVIEW Categories. FieldPoint can be used for monitoring C type thermocouples. The FP-TC-120 modules does not directly support C type thermocouples, so instead of configuring an FP-TC-120 for temperature mode, you would configure it for voltage mode, set the appropriate range, read the input channel and the CJC channel, and do the scaling in software. A FieldPoint System would be comprised of a network module (FP-1000, FP-1001, FP-1600, FP-2000 or FP-2010), terminal base(s) (FP-TB-3 recommended for use with thermocouple modules) and an I/O module(s) (FP-TC-120 for thermocouple measurements).
