Note:

Input drift + output drift = total drift, the effect of ambient temperature change of 1 °C.
The input drift is the part of the input signal drift below zero. For example, Pt100, the zero point of 0~100°C is 100Ω, the drift is input drift; the output value is 38.5Ω, and the drift is output drift. The total drift index is: 138.5X0.0015%=2mΩ, less than 4mΩ, taking 4mΩ, and the relative value of temperature drift is: 4mΩ/38.5Ω≈0.01%FS/°C.
