* Defined as ±2 standard deviation limits of endpoint non-linearity,

hysteresis error or repeatability error and calibration.

** Defined as ±2 standard deviation limits of accuracy of the working

standard including traceability to NIST.

*** Defined as the root sum of the squares (RSS) of endpoint 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.
