Getting started - Data transfer

Data transfer

Data is transferred between the measurement device and the laptop/
PC either via a direct connection or a network connection. This
relates to the following data:

-

Measurement tasks to VIBXPERT (route)

-

Measurement data to the PC (route, multimode, templates)

-

Machine templates to VIBXPERT

-

Software (update)

-

Printer drivers to VIBXPERT

-

Data backup to the PC

-

Data restore to VIBXPERT

-

PDF and screenshots to the PC

Measurement tasks, measurement data and machine templates are
transferred using the OMNITREND PC software. All other data are
exchanged via the 'VIBXPERT utility' tool found on the PRÜFTECH-
NIK CD and that must be installed locally on the PC.
