1) Accuracy: Refers to the root mean square difference between the measured value and the actual angle error obtained by measuring the angle multiple times (>16 times) at room temperature.
2) Zero point temp. Coefficient: refers to the rate of change in the displayed value of a sensor relative to normal temperature within its rated operating temperature range when it is in a zero state.
3) Sensitivity temp. Coefficient: refers to the percentage of full-scale indication of a sensor relative to full-scale indication at room temperature within its rated operating temperature range, and the rate of change with temperature.
