Before discussing calibration math, confirm that the hardware is stable enough to deserve calibration effort.

  • Reference source stability
  • Thermal behavior
  • Sensor warm-up and settling
  • Fixture repeatability
  • Environmental dependence and aging

A beautiful calibration model cannot rescue an unstable measurement chain.
