A memory module belonging to the stabil ion gauge (serial 06800) was provided. It was active during calibration. \section{ Calibration procedure } The device was installed in a vertical orientation. Before calibration the gauge head was baked at \(?\) °C for \(?\) h. During the cool down phase the head was degassed for \(?\) minutes. At room temperature it was exposed for \(?\) h at \(?⋅10^{?}\) mbar argon for sputtering the ion collector. The sensitivity factor was kept at an value of \(?\) mbar\(^{-1}\) during the calibration. The calibration was carried out with the following device settings: \begin{itemize}\item display: mbar\item filament: F1\item emission: L\item channel: A\end{itemize} Before each calibration point the residual pressure indication \(p_r\) was checked. The temperature \(θ\) during the calibration was \(?\) °C and varied from this value within \(\pm?\) °C. The device was calibrated with ? in the pressure range \(?⋅ 10^{?}\) mbar to \(?⋅10^{?}\) mbar by comparing its reading with the calibration pressure that was established by the primary standard CE3 of PTB applying the continuous expansion method. \section{ Relative error of indication } The correction factor \(CF\) given in the table below was calculated from the indicated pressure \(p_{ind}\) as follows:\[CF =\frac{p_{cal}}{p_{ind} - p_{r}}\] where \(p_{cal}\) denotes the calibration pressure as generated in the primary standard and \(p_{r}\) the reading at residual pressure. From this, the corrected pressure \(p\) can be calculated from the residual pressure indication and the indicated pressure by:\[p = CF (p_{ind} - p_{r})\] The uncertainty \(U\) of \(CF\) at the time of calibration is given in the last column of the table below. It includes the repeatability of \(p_{ind}\) for otherwise identical conditions (\(p_{cal}\), \(θ\)).\printResultTable \section{ Uncertainty of Calibration } The uncertainty \(U\) stated is the expanded measurement uncertainty obtained by multiplying the standard measurement uncertainty by the coverage factor \(k = 2\). It has been determined in accordance with the “Guide to the Expression of Uncertainty in Measurement (GUM)”. The value of the measurand then normally lies, with a probability of approximately \(95\) \%. within the attributed coverage interval.\par \(95\)\,\% 95\,\% 95~\% \(95\) \% \par 95 \% 95 \% \printLastPage \end{document} %--------------------------- \(95\)\,\% 95\,\% 95~\%
