PRODUCTION DATA.
Figure 61 shows the resistance measurement results. The measurements are taken at TA = 25°C. The data are taken using a precision resistor simulator with a 3-wire connection in place of the RTD. A system offset calibration is performed using shorted inputs. A system gain calibration is performed using a 390-Ω precision resistor. The measurement data are in ohms and do not include the error of the RTD sensor. The measured resistance error is < ±0.02 Ω over the 20-Ω to 400-Ω range.
