First, attempt to correct the problem before retrying the store operation. See Section10.2.5
“Formatting Disks” on page 10-6 for an explanation of disk formatting procedures.
A write-protected disk can be made writable by moving the write-protect tab on the rear of the disk so
that the hole at the top of the switch is completely covered. Exposing the hole makes the disk read-only
and prevents any further writing (see Fig ure10- 2 on page10-3).
10.2.3 Storing Balance Charts to Disk
Storing balance charts to disk provides a means to copy charts from one disk to another. It also
provides a means to rename charts, which is important if a chart has been corrected. Corrected charts
are always unique to a specific rotor. To store a particular chart, first put the 8500C/C+ in Balance
mode. Press
SEL CHART
to display the list of available charts, and use the Arrowkeys to highlight the
desired chart. Press
STORE
to store the chart to disk. You are then asked to give the chart a new name
before it is actually written to disk. Make sure the name you supply provides a unique identification for
the chart, the rotor type and tail number of the aircraft, for example, although it is not necessary to
rename the file before storing it. When a chart is stored to disk, a balance chart file is created
containing the renamed chart plus other related charts associated with the file. The new chart file
replaces an existing chart file with the same name. Note that balance histories are never written to disk
during a chart store operation. This action must be done intentionally by the user ( see Section5.6.1.3
“Storing Histories to Disk” on pa ge5-16).
To store all the charts listed on the balance chart selection menu, press
MORE KEYS
and th
STORE ALL
soft key.
STORE ALL
stores all the charts currently in static memory to the appropriate
chart file(s) on disk. Charts are written as is without renaming, so you are not asked to create new
names.
When you press
STORE
(but not
STORE ALL
), the 8500C/C+ enters its edit mode of operation and
displays the Balance Chart Edit screen (see Figure 10-3). The soft keys and procedures used here are
identical to those used to edit the printout annotation. See Section8.3 “Annotating Printouts” on
page 8-5 for a complete description. When you are satisfied with the chart name, press th
ENTER
soft
key to write it out to disk. Note that when a chart is stored to disk, a new balance chart file is created
containing the renamed chart plus the other charts associated with the file. If the chart has the sam
name as a chart already on disk, the latter is overwritten (unless it is a distribution chart on a
distribution disk, in which case an error results). When the chart has been stored, the list of available
balance charts displays again, and the name of the stored chart is updated accordingly.
