OUTPUT

PROCESSING INSTRUCTIONS

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.

Othenryise,

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

10"C

Upper range

A

common

use of

a

weighted value

histogram

is

the wind

Wind speed

values

(the

weighted value input) are

accumulated into corresponding

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.

lf houdy 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

2lor

the day code causes

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 ne)it minute is

still0001).

When day

and hour-minute are both output,

a 2

for

either

code

results

in

the

previous

day

at2400.

The

year

is output

as

19xx

if

xx

is

greater than

85, otherwise

it

willbe

output as

20xx.

The

CR10

will

require

a

PROM update

in

the year

2085.

lf 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.
