# Sensor-chain error budget
# Scope: Worst-case additive offset, gain and quantization bounds.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

reading = 50 mm
offset = 0.1 mm
gainError = 0.002
quantization = 0.01 mm

bound := offset+abs(reading)*gainError+quantization/2 [mm]

check measurement error budget: bound <= 0.3 mm

scenario alternative: reading = 40 mm
