SECTION 11. OUTPUT PROCESSING INSTRUCTIONS
11-4
while the bin select value was within a particular
sub-range, the value output to Final Storage
must be divided by the fraction of time that the
bin select value was within that particular sub-
range (i.e., a standard histogram of the bin
select value must also be output).
For either histogram, the user must specify: 1)
the number of repetitions, 2) the number of
bins, 3) a form code specifying whether a
closed or open form histogram is desired (see
below), 4) the bin select value input location,
5) the weighted value input location (see
below), 6) the lower range limit, and 7) the
upper range limit.
The standard histogram (frequency distribution)
is specified by entering "0" in the weighted value
input location parameter. Otherwise, this
parameter specifies the input location of the
weighted value. When more than one repetition
is called for, the bin select value location will be
incremented each repetition and the weighted
value location will remain the same (same
weighted value sorted on the basis of different
bin select values). The weighted value location
will be incremented if it is entered as an indexed
location (key "C" at some point while keying in
Parameter 5; two dashes, --, will appear on the
right of the display). At the user's option, the
histogram may be either closed or open. The
open form includes all values below the lower
range limit in the first bin and all values above
the upper range limit in the last bin. The closed
form excludes any values falling outside of the
histogram range.
The difference between the closed and open
form is shown in the following example for
temperature values:
Lower range limit
10

C
Upper range limit
30

Open Form
Range of first bin
10 to 11.99 deg.
<12 deg.
Range of last bin
28 to 29.99 deg.
>28 deg.
A common use of a closed form weighted value
histogram is the wind speed rose. Wind speed
values (the weighted value input) are
accumulated into corresponding direction
sectors (bin select input).

FUNCTION
This Instruction stores the current time in Final
Storage. At midnight the clock rolls over from
23:59 to 00:00. The day also changes.
If hourly or daily summary data is output, it may
be desirable to have the previous day output,
since that is when the measurements were
made. Entering a 2 for the day code causes the
previous day to be output if it is the first minute
of the day. Similarly, entering 2 for the hour-
minute code causes 2400 instead of 0000 to be
output (the next minute is still 0001). When day
and hour-minute are both output, a 2 for either
code results in the previous day at 2400.
If year is output along with a 2 option in day or
hour-minute, the previous year will be output
during the first minute of the new year.
