Returns

DerrTCE_TYPE Invalid thermocouple type

DerrTCE_PARAM Parameter out-of-range

DerrNoError No error

For more details on error messages refer to the Daq Error Table.

Function Usage

For all functions of the form daqCvt..., raw data to be converted must be unsigned

(i.e., the dafUnsigned value must be set using the daqAdcSetScan function).

For T/C and RTD conversion, users of Daq/2000 Series devices* and/or Daq PC Cards must

be sure that the main unit is using ten volt range gains settings, either unipolar (0 V to 10 V)

or bipolar (-5 V to +5 V).

See the “T/C Gains Settings” section in the daqCvtTCConvert function entry for the

appropriate settings.

* Daq/2000 Series devices include DaqBook/2000 Series, DaqScan/2000 Series, DaqLab/2000

Series, and DaqBoard/2000 Series devices.

The daqCvtTCSetupConvert function combines the operationns of the both the daqCvtTCConvert

function and the daqCvtTCSetup function. For more detailed information on using thermocouples (T/Cs)

and converting data refer to the entries for daqCvtTCConvert and daqCvtTCSetup

The daqCvtTCSetupConvertF function combines the operationns of the both the daqCvtTCConvertF

function and the daqCvtTCSetup function. For more detailed information on using thermocouples (T/Cs)

and converting data refer to the entries for daqCvtTCConvertF and daqCvtTCSetup
