CR800, CR1000, CR3000 Changes

June 17, 2011

Fixed typographical errors, added hyperlinks, added indexing


Fixed Appendix page numbering to be continuous w
ith the rest of the manual. A side effect of doing this, due to
Author-it
/
MSWord
interactions,
is
that
all
appendices
are
“
Sections”
and
numbered
in
sequence
w
ith
non-appendix sections.

Fixed changes posted in DocT
ool. Thanks go to Dana, Cliff, Sam, and Linda.


Changes:
Referenced section numbers may vary slightly betw
een from CR800, CR1000, and CR3000 manuals.

2. Quic
kstart Tutorial
Re-
organized

3.1.5 Memory and Data Storage
Mention use of USR: and USB: for TableFile() instruction files.


3.1.6.3 Via CF Card
Modified to recommend stopping the datalogger program w
hen collecting CF data via telecommun
ications.


3.1.6.4 Data File For
mats in Memory.

Added to addr
ess T
ableFile() instruction files for
mats


3.1.9.1 P
rotection from Water

added


3.1.9.4 Internal Battery

changed life expectancy of the internal battery to 3 years

3.3 Specifications

added to Digital IO Ports Section:
INPUT RESIST
A
NCE:
100 kohms
w
ith inputs <6.2 Vdc
220 ohm w
ith inputs ≥ 6.2 Vdc


4.1 Time. New
section. Time Stamps section made a sub- section of Time section.

Old 4.2 Pow
ering Sensors. This section modified and made a sub-section to Section 6. Pow
er Sources
Add control ports and current source limit.

Re-w
orked Table. Current Source & Sink Limits

Corrected ranges mV5000 and mV
2500 in T
able. Analog Voltage Input Ranges


4.2.9 Self-Calibration
Added note to answ
er the question
hy do I need to send it in for calibration?


4.2.10 Time Skew
Betw
een Measurements

Added

4.3 Br
idge Res
istance
Removed reference to current excitation bridge circuits.


FIGURE. Voltage E
xcitation Br
idge Circuits changed to T
A
BLE. Resistive Br
idge Circuits
–
Voltage E
xcitation.
Added a key to math sy
mbols. Corrected equation for Br
Half (replace Rx in denominator to Rs).

4.5.3 Pulse Measurement Tips

Add bullet: As show
n in Figure. Connecting Sw
itch Closures to Digital I/O, digital I/O inputs, w
ith regard to the
6.2 V Zener diode, have an input resistance of 100 kohms w
ith input voltages < 6.2 Vdc. For input voltages >=
6.2 Vdc, the inputs have an input res
istance of only 220 ohms.


6.0 Pow
er Sources.

Changed section heading from “
P
ow
er Supply.”
Moved old
Section 4.2.
Pow
ering Sensors here and renamed
6.5 Pow
ering Sensors and Devices.


8.1 Dev
Config
Add paragraph at beginning of section instructing the user to connect the datalogger to the
PC via serial cable.

Old 8.3.3 Settings via Ter
minal Emulator

Removed
this
section
to
Section
18.5
T
er
minal
Emulator
(sub-section
of
Section
18.
Troubleshooting).
Re-w
orked and included infor
mation on sniffing ports and added more description of available commands.

8.3.3.2 1 File
added caution “
If the intent is to load operating systems via telecommunications and have a 1 file in
the CR1000, the 1 program should not use significant memory, such as occurs by allocating a large

USR: drive, or by using a DataT
able() instruction w
ith auto allocation of memory.”


8.3.5 Netw
ork P
lanner.
Added

9.5.1 Var
iables

Added to end of intro section:
Variables can also be assigned initial values in the declaration.

Public SetT
emp = {35} is an example of dec
laring a var
iable and assigning it an initial value.


9.5.1.2.1 Dimensioning Strings
Added to clarify string dimensions


9.5.1.3 Data T
ypes

Added caution about mixing data types w
ithin an array
Added UINT4 to T
ABLE
. Data T
ypes


9.5.1.6 Local Variables

Added recommendation to declar
ing global
and local variables
w
ith same
data type and string length w
hen
declaring passing / receiving pairs.


9.6.1.1 DataTable() and EndTable () Instructions

Added
note
under
bullet
point
“
Name”
--
While
other
characters
may
pass
the
precompiler
and
compiler,
runtime errors may occur if the naming rules are not adhered to.


9.6.1.3 OpenInterval() Instruction
Replaced 2nd paragraph w
ith “T
ypically, time series data (averages, totals, maximums, etc.) that are output
to a
table based on an interval only include measurements from the current interval. After each output interval, the
memory that contains the
measur
ements for the time ser
ies
data is
cleared.
If an output
interval
is
missed
(because all criteria are not met for output to occur), the memory is cleared at the top of the next interval. If the
OpenInterval instruction is contained in the DataT
able declar
ation, the memory is not cleared. This results in all
measurements being included in the time ser
ies data since the last time data w
as stored (even though the data
may span multiple output intervals).”


9.8.1 Scan () / NextScan
100 ms scan r
esolution changed to 10 ms


9.9.3 Names in Parameters
Added
footnote
to
T
ABLE
.
Rules
for
Names:
“Variables/Constants,
Units
,
Alias,
StationName,
FieldNames,
DataT
able names, and file names can share same names, i.e., once a name is used, it is reserved only in that
category.”


9.13.1 Use of Variable Arrays to Conserve Code Space
Added “
Note
--
When
using the () syntax, w
hether on the disable
parameter
or w
ith
multiplier and
offset on
measurement
instructions,
if
the
parameter
expression
is
more
than
a
simple
reference
to
a
var
iable,
e.g.,
disvar() + 5, or multiplier() * 4, or NOT enable_var(), the () syntax is ignored and reps w
ill not take place for the
expression.”


10.5.9 Specific Sensors (CRBasic Instructions)
Added A
CPow
er() instruction

10.7.2 Str
ing Commands.
Rev
ised description of ArrayLength() instruction.
