Storing

Data

- Data are

stored

in Final

Storage only by

Output

Processing

Instructions and only when the

Output

Flag

is

set.

(Sections OV4.1.1 and OV4.2.1)

Storing

Date

and Time -

Date and

time

are

stored with the

data

in Final Storage ONLY

if

the

Real

Time InstructionTT

is used.

(Section

11)

Data

Transfer

-

On-line

data

transfer

from

Final Storage

to

peripherals (printer,

Storage Module, etc.) occurs only

if

enabled

with

lnstruction

96

in

the

datalogger

program.

(Sections

4

and

12)

FinalStorage

Resolution

-

All

lnput

Storage values are

displayed (.6

mode) as

high resolution with

a

maximum value

of

99999.

However,

the default

resolution

for

data stored in Final Storage is low

resolution, maximum value of 6999.

Results exceeding 6999 are stored as 6999

unless lnstruction

78

is used to store

the

values in Final Storage

as

high resolution

values.

(Sections2.2.1 and

11)

Floating Point Format

-

The computations

performed

in

the

CR10 use

floating

point

arithmetic.

CSI's 4 byte

floating

point

numbers

contain

a 23 bit binary mantissa

and

a

6 bit binary

exponent. The

largest

and smallest numbers that

can

be stored

and processed

are

9

x

1O18and 1

x

10-1e,

respectively.

(Section 2.2.2)

Erasing

Final

Storage

-

Data in Final

Storage

can

be erased without altering

the

program

by

using

the "A

Mode

to

repartition

memory.

(Section 1.5.2)

ALL memory can

be erased

and

the

CR10

completely

reset by

entering

1986 for

the

number

of

bytes left

in

Program Memory.

(Section 1.5.2)

The

set

of instructions

available

in

the

CR10

is

determined by

the

PROM

(Programmable Read

Only

Memory)

that

it

is

equipped

with.

Standard and optional

software

are

identified

in

Appendix

B.

lf

you

have ordered optional software

that

is not

covered

in

the

standard manual,

the

documentation

is

in

Appendix

H.

Radiotelemetry

Users

-

As

of

February,

1990,

CR10

PROMs no longer contain

radio

frequency

interface

sottware.

That

function

is now

contained

in

the

RF95

Modem.

To

make

measurements

at a

phone-to-RF base

station

using

the

RF100/RF200 Radio and RF95 Modem,

current CR10 software

is required. A

CR10

with old software

can

be used with

the

new

RF95

in

the

"RF9S-ME" state, but

the

datalogger loses

the

"callback" capability as

wellas

the

SDC function.

10.

Changes

with the

release

of

OS10'0.1:

Wind Vector

Instruction

69 has

replaced

lnstruction

76.

The options to do sub-

interval averaging

of

the

standard deviation

of wind direction,

o(0),

and to calculate o(0)

using the

Yamaftino algorithm

have been

added to

the

previous

options

(Section

9).

Intermediate Processing Disable

Flag

9

in now set low

if a

conditional test for setting

it high

fails

(same as

Output

Flag 0, Section

3.7.2).

*D

options for

saving and loading

programs

with

a

cassette tape

are

no

longer in a

standard

PROM

and

must be

ordered as

a

library

option

PROM

(Appendix

B).
