1 Precision is defined as the combined effects of linearity, repeatability
and hysteresis throughout the operating temperature range.
2 Total uncertainty is the maximum deviation from the true value of
pressure including precision, stability, temperature effects and the
calibration standard. This assumes routine zeroing of the instrument.
Expression of uncertainty conforms with the recommendations of the
ISO Guide to the Expression of Uncertainty in Measurement.
