1 Defined as ±2 standard deviation limits of
endpoint non-linearity, hysteresis error, or repeatability error.
2 Defined as ± 2 standard
deviation limits of inaccuracy of the working standard including traceability to
NIST.
3 Defined as the root sum of
the squares (RSS) of endpoint 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.
