Approvals
Instruments with approvals can have dierent 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".
10.2 InformationonProbusPA
Instrumentmasterle
The instrument master le (GSD) contains the characteristic data of the Probus PA instrument.
These data are, e.g. the permissible transmission rates as well as information on diagnostics values
and the format of the measured value outputted by the PA instrument.
A bitmap le is also provided for the Probus network planning tool. This le is installed automati-
cally when the GSD le is integrated. The bitmap le is used for symbolic indication of the PA instru-
ment in the conguration tool.
Ident number
Each Probus instrument gets an unambiguous ident number (ID number) from the Probus user
organisation (PNO). This ID number is also included in the name of the GSD le. For VEGABAR 66
the ID number is
0x076F(hex) and the GSD le BR__076F.GSD. As an option to this manufactur-
er-specic GSD le, PNO provides also a general so-called prole-specic GSD le. For VEGABAR
21)
Instruments with gauge pressure measuring ranges cannot detect the ambient pressure when submerged, e.g.
in water. This can lead to falsication of the measured value.

Only with instruments with absolute pressure ranges.
