The D/A conversion error of this transmitter is relatively very small so that it does not really affect the unit’s overall performance. The “Accuracies” given in Table 1 therefore equals the A/D conversion error. The temperature drift (coefficient) or the cold junction compensation error is not included in the “Accuracy.” ■ CALCULATION EXAMPLES OF OVERALL ACCURACY IN %
