Measuring uncertainty in accordance with GUM: ±0.5 % of measuring range
final value ±0.3 Pa.
The determination of measurement uncertainty takes place according to GUM (Guide to the Expression
of Uncertainty in Measurement):For the determination of measurement uncertainty, the accuracy of the
measuring instrument (hysteresis, linearity, reproduceability), the uncertainty contribution of the test site
as well as the uncertainty of the adjustment site (works calibration are taken into account. For this
purpose, the value of k=2 of the extension factor, which is usual in measurement technology is used as
a basis, which corresponds to a trust level of 95%.

Minor mixtures of the media may occur at the positive and negative pressure
side due to the automatic zeroing cycle.
