* Defined as the ±2 standard deviation limits of end-point non-linearity, hysteresis

error or repeatability error.

** Defined as ±2 standard deviation limits of inaccuracy of 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 as ±2 standard deviation limits of temperature dependence over the

operating temperature range.
