Print
shows you how often the summary data is printed. The possible values
are the same as those for collection. Note that the VR240 will not allow
you to select a print interval that is shorter than the collection interval.
Each printout comprises a heading and shows the interval covered by the
printout. Depending upon the ratio between the summary interval and the
printout interval, from 1 to 288 lines of summary data will appear on each
printout.
NextRpt
(next report) shows you when the next summary will be printed. This is
selected automatically for printer intervals up to 1 hour. If you select an
interval longer than 1 hour, you have the opportunity to change the time
that the report is printed.
The soft keys under the display permit you to change the numbers in the
display, hence the report characteristics.
Cursor
selects which of the three items is presently under control. If
None
is
selected, the cursor remains under
SUMMARY
. If a summary interval of
up to 1 hour is selected, the cursor alternates between
SUMMARY
and
PRINT.
And if a
PRINT
interval of greater than an hour is selected, the
cursor alternates among the three choices.
Change
modifies the displayed time of the feature selected by
CURSOR
.
Done
accepts the changes you have made and drops back to the previous
menu.
Cancel
returns to the previous menu without modifying the settings.
Quit
returns to the
Config
menu from which you originally selected
StatReport.
3-10. TIME TRACK.
Time Track
is a feature that can be enabled to assure that the media is “always running.” One
of the main advantages to the VR240 is that no space on the media is used when there is
nothing to record. In some applications, however, it is desirable to have a continuous time track
to be able to prove that the media was running continuously and that no input was missed
because it was temporarily stopped. Normally, simply recording a single channel on a
continuous basis will accomplish this, even if all the other channels are intermittent. If, however,
you are not recording continuously, you can turn the
Time Track
on to provide a record of
continuous recording.
Selecting
Time Track
to
On
will put a time mark on the media once per second if no actual
recording is being performed. There is a penalty in that this feature uses, at most, the
equivalent of one-half of an audio channel (at the slowest sampling rate) of media time, even if
nothing is being recorded.
Time Track
is only activated when necessary to provide a time
mark. If at least one channel is being recorded most of the time, the “wasted media” penalty is
substantially less. In the worst case, if nothing is being recorded at all,
Time Track
will fill the
medium in about twice the number of hours that the medium has available in “channel hours.”
