1) Defined as the ±2 standard deviation limits of end point non-linearity, hysteresis error, or
repeatability error.
2) Defined as ±2 standard deviation limits of inaccuracy of the working standard including
traceability to international standards.
3) Defined as the root sum of the squares (RSS) of end point non-linearity, hysteresis error,
repeatability error, and calibration uncertainty at room temperature.
4) Defined as ±2 standard deviation limits of temperature dependence over the operating
temperature range.
