items continue to be added to static memory until the available space is exhausted. Thus, it may
become necessary from time to time to clear out some items from static memory and purge the data
accumulated there.
To clear out the portion of static memory containing balance charts and histories, press
CLR CHARTS
.
Balance charts, chart corrections, and balance histories are then deleted from static memory, and all
chart names removed from the menu in the Select Chart screen. Since the Measurements Only chart is
permanent, it cannot be deleted.

soft key displays important information about the currently selected rotor system,
such as the location of system balance points, the installation of vibration transducers and retro
reflective targets, and the orientation of the reference azimuth for determining phase angle (se
Figur e5-5 on pag e5-6).
CAUTION: This information is essential to the correct setup of the system prior to
balancing. Be sure to read it thoroughly and follow any given instructions.
The

and
