Metrological characteristics | |||
Range Uncertainty by type A (uA) | from 1·107 Pa to 4·108 Pa | ||
from 1·107 Pa to 6·107 Pa | from 6·107 Pa to 4·108 Pa | ||
Uncertainty by type B (uB) | 5,5·10-6 | 7,5·10-6 | |
Total standard uncertainty (uC) | \(\sqrt{(8,0·10^{-6})^2+(1,8·10^{-13} p)^2}\) | \(\sqrt{(1,4·10^{-5})^2+(8,2·10^{-14} p)^2}\) | |
Extended uncertainty (U) | 1,0·10-5 + 8,0·10-14 р | 1,6·10-5 + 5,1·10-14 р | |
Розширена невизначеність (U) | 2,0·10-5 + 1,6·10-13 р | 3,2·10-5 + 1,0·10-13 р, (р – numerical value of pressure in Pa)
