In this menu, you can format, check and repair the memory card.
formatting: You should only format a card if it is new and has not yet
been used in VIBXPERT. This process deletes are data stored on the
card!

repairing: If the file system on the memory card is faulty, an error mes-
sage appears. If possible, save the measurement data on the PC
before starting the repair function.
Standardization factor for dB scaling
The amplitude of a spectrum is converted to decibels (dB) with the
following formula:
A
log
= 20*log(A
lin
/N), where A
log
: amplitude in dB
A
lin
: amplitude in linear unit
N: standardization factor
In this menu, you can set the standardization factor (default = 1).
The scaling that is used for a spectrum (linear or in dB) is defined in
theDisplaySetup(seeChapter4).
The dB scaling is not available for time signals, overall values and
