Approvals
Instruments with approvals can have different technical data depending on the version.
For that reason the associated approval documents of these instruments have to be carefully
noted. They are part of the delivery or can be downloaded under www.vega.com via "VEGA Tools"
and "serial number search" as well as via "Downloads" and "Approvals".
17) Instruments with gauge pressure measuring ranges cannot detect the ambient pressure when submerged, e.g.
in water. This can lead to falsification of the measured value.
18) Only with instruments with absolute pressure ranges.
