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".
11.2 Overview applications/functionality
The following charts provide an overview of the standard applications and functions of signal condi-
tioning instruments VEGAMET 391/624/625 and VEGASCAN 693. They also give information about
whether the respective function can be activated and adjusted via the integrated indicating and
adjustment unit (OP) or via PACTware/DTM.
