Figure 3-5 to Figure 3-7 illustrates the RTD resistance measurement percent error. Through out all three sets of collected data, the common mode voltage (Vcm) have a small effect on the result. All captured data shown in Figure 3-7 have percent error less than 0.07% error. Therefore, it is recommended to bias the RTD current at around 1.5 mA for the best performance.
