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