Automatic Zero Compensation

The

tbkTCAutoZero

function will configure the thermocouple linearization functions to automatically

perform zero compensation. This is the easiest way to use zero compensation when making thermocouple

measurements. When enabled, the thermocouple conversion functions will require a CJC zero reading and

a TC zero reading to precede the actual CJC and TC reading.

int tbkTCAutoZero ()

uint zero

If non-zero, will enable auto zero compensation in the tbkTC... functions

Note

: See the thermocouple linearization section for a description and example of automatic zero

compensation for thermocouple measurement.
