Parameters
uint startchan Single channel number (see table at end of chapter for valid values)
uint endChan Ending channel of the scan group (see table at end of chapter for valid values)
uint tcType Thermocouple type (see table at end of chapter for valid values)
int *temp An array where the A/D scan will be placed.
Returns TerrInvChan - Invalid Channel

tbkRdTempScan is used to take thermocouple readings from analog input channels 'startChan'
through 'endChan'. The readings will be zero corrected, span corrected, and linearized to yield
temperature readings in tenths of a degree Celsius. This function will use software triggering to
immediately trigger and acquire one scan.
If a calibration constant file with the default name "tempbook.cal" is not visible to the calling
program, then no span correction is performed.
tbkSetMode must be called before this function to configure the TempBook for differential
operation in either unipolar or bipolar mode.
