OV1.1.2 Signal Grounds ( )
Signal Grounds ( ) should be used as the reference for Single-ended Analog
inputs, Pulse inputs, Excitation returns, and sensor shield wires. Signal returns
for the Pulse inputs should use the
inputs.
OV1.1.3 Power Grounds (G)
Power Grounds (G) should be used as the returns for the 5V, SW12, 12V, and
C1-C8 outputs. Use of the G grounds for these outputs with potentially large
currents will minimize current flow through the analog section, which can
cause Single-ended voltage measurement errors.
OV1.1.4 Ground Lug ( )
The large ground lug is used to connect a heavy gage wire to earth ground. A
good earth connection is necessary fix the ground potential of the datalogger
and to send to earth transients that come in on either the G or
are shunted to ground via the spark gaps protecting other inputs.
OV1.1.5 Power In (G and 12V)
The G and 12V terminals on the Power In connector plug are for connecting
power from an external battery to the CR1000. These are the only terminals
that can be used to input battery power; the other 12V and SW-12V terminals
are output only.

terminals or
OV1.1.6 Switched 12 Volts (SW-12)
The SW-12 terminal provide an unregulated 12 volts that can be switched on
and off under program control.
OV1.1.7 Switched Voltage Excitation (EX E1-3)
Three switched excitation channels provide precision programmable voltages
within the ±2.5 Volt range for bridge measurements. Each channel will source
up to 2.5 mA at voltages up to ±2.5 Vdc.
OV1.1.8 Digital I/O (C1-8)
There are 8 digital Input/Output channels (0 V low, 5 V high) for frequency
measurement, pulse counting, digital control, and triggering. In addition to the
individual channel digital I/O functions, there are several groups of channels
that can be used for other functions.
The Synchronous Device for Measurement (SDM) connections C1, C2, and C3
along with the 12 volt and ground terminals are used to connect SDM sensors
and peripherals.
The COM groupings can be used for serial I/O communication and Intelligent
Sensor input.
OV1.1.9 Pulse Inputs (P1-2)
Two Pulse input channels can count pulses from high-level (5 V square wave),
switch closure, or low-level A/C signals.

card for removal before switching off the CR1000 power.
All Campbell Scientific communication peripherals connect to the CR1000
through the 9-pin subminiature D-type socket connector located on the front of
the Wiring Panel labeled “CS I/O” (Figure OV1-3). Table OV1-1 gives a brief
description of each pin.

OV1.2.3 Computer RS-232
The CR1000 RS-232 port is not isolated.
Direct connection of the CR1000 to a PC is most conveniently done through
the "Computer RS-232" port (Figure OV1-3). Table OV1-2 gives a brief
description of each "Computer RS-232" pin.
The Computer RS-232 port is a DCE device when connected to a PC with a
serial cable. It also doubles as a DTE device when connected to a modem
device through a null-modem cable. (DTR function is on pin I, Ring is an

CR1000 Overview
OV1.3 Power Supply and AC Adapter
The CR1000 requires a separate 12 V power supply. The PS100 power supply
has a 7 amp hour battery with built-in charging regulator. Optional adapters
for AC power are available. Charging power can also come from a 17-28
VDC input such as a solar panel.
OV2. Memory and Operating Concepts
OV2.1 Memory
The CR1000 has two MB Flash EEPROM that is used to store the Operating
System. Another 128 K of Flash is used to store configuration settings. A
minimum of 2 MB SRAM (4 MB optional) is available for program storage
(16K), operating system use, and data storage. The size of available memory
may be seen in the status file. Additional data storage is available by using a
compact flash card in the optional CFM100 Compact Flash Module or NL115
Ethernet Interface and Compact Flash Module.
OV2.2 Programming
The CR1000 program directs how and when the sensors are measured and data
are stored. The program is created on a computer and sent to the CR1000.
The CR1000 can store a number of programs in memory. Campbell Scientific
has two software applications that create CR1000 programs: ShortCut and the
CRBasic Editor.
For many applications ShortCut is a good place to start. With ShortCut you
select the sensors to measure, the units to report the measurements in, and the
data to output. ShortCut supports most of the sensors sold by Campbell
Scientific as well as generic measurements. The CR1000 programs created by
ShortCut are generally clear and provide a good example of CRBasic code for
those who wish to write CR1000 programs themselves.
For those that have the need or inclination to tackle more complex programs,
the CRBasic Editor is used to create and edit the CRBasic programs that the
CR1000 runs. Section 4 provides an introduction to CRBasic Programming.
The CRBasic Editor has syntax highlighting and online help for the CR1000
instruction set described in Sections 5-12.
ShortCut is included with PC200, PC400 and LoggerNet and is available for
free from the Campbell Scientific web site. The CRBasic Editor is included in
PC400 and LoggerNet.
OV2.3 Instruction Execution within the Datalogger
OV-6
The execution of instructions within the datalogger is accomplished using three
separate task types: measurement, SDM, and processing. As it is named, the
measurement task handles measuring the signals received on the datalogger’s
wiring panel, as well as outputting signals for control of other devices. The
measurement and control hardware is manipulated on a rigidly timed sequence.
The SDM task handles the measurement and control of most SDM devices.
CR1000 Overview
The processing task converts the raw signals read by the datalogger into
numbers representing engineering units, performs calculations, stores data,
makes the decisions to actuate controls, and performs serial I/O
communication.

The datalogger can execute these tasks in either pipeline or sequential mode.
When a program is compiled the datalogger evaluates the program and
determines which mode to use. This information is included in a message
returned by the datalogger and is displayed by the support software.
CRBasic’s precompiler returns a similar message. A program can be forced to
run in sequential mode by placing the SequentialMode instruction in the
declarations section of the program.
OV2.3.1 Pipeline Mode
In pipeline mode, the measurement task, SDM task, and processing task are
three separate functions. In this mode the three tasks may operate
simultaneously. The measurement tasks are scheduled to take place at exact
times and with the highest priority when the datalogger starts each scan. This
results in a more precise timing of measurements, and may be more efficient
with processing and power consumption. However, this prescheduling of
measurements means measurement instructions must be executed every scan,
and because multiple tasks are taking place at the same time, the sequence in
which the instructions are executed may not be in the exact order in which they
appear in the program. For these reasons, conditional measurements are not
allowed in pipeline mode. Also note that because of the precise execution of
measurement instructions, processing for the measurements in the current scan
(including update of public variables and output to data tables) is delayed until
all measurements are completed.
OV2.3.2 Sequential Mode
In sequential mode the instructions are executed in the sequence they appear in
the program. Sequential mode can be slower than pipeline mode since it does
only one step of the program at a time. After a measurement is made the result
is converted to a value determined by the processing included in the
instruction, and then the datalogger proceeds to the next instruction. Because
of this step-by-step instruction execution, conditional measurements are
allowed in sequential mode. The exact time at which measurements are made
may vary if other measurements or processing are made conditionally, if there
is heavy communications activity or other interrupts (e.g., inserting a CF card).
OV-7
CR1000 Overview
OV2.3.3 Slow Sequence Scans
OV2.3.4 Task Priority
The datalogger allows for one or more scans that are run outside of the
instructions placed between the Scan/NextScan instructions in the main
program. These scans, referred to as slow sequence scans, typically run at a
slower rate than the main scan. Up to four slow sequences can be defined in a
program (slow sequences are declared with the SlowSequence instruction).
Instructions in a slow sequence scan are executed whenever the main scan is
not active. When running in pipeline mode, slow sequence measurements will
be spliced in after measurements in the main program, as time allows. Because
of this splicing, the measurements in a slow sequence may actually span across
multiple main program scan intervals. In sequential mode, all instructions in
the slow sequences are executed as they occur in the program (see Task
Priority, below).
When considering the information above regarding pipeline and sequential
mode, you must also consider that some sequences in the program may have
higher priorities than other sequences in the program, and that measurement
tasks generally take precedence over all others. In addition, the priority of
sequences is different for pipeline mode and sequential mode.
When running in pipeline mode, measurement tasks have priority over all other
tasks. Measurements in the main program have the highest priority, then
background calibration, followed by any measurements in slow sequences that
may be defined. The execution of processing tasks are handled by a task
sequencer, and all tasks are given the same priority. When a condition is true
for a task to start running it is put in a queue (this true condition can be based
on time, the triggering of WaitDigTrig, the expiration of a Delay instruction, or
a ring on a COM port triggering communication). Because all tasks are given
the same priority, the task is put at the back of the queue. Every 10 msec (or
faster if a new task is triggered) the task currently running is paused and put at
the back of the queue, and the next task in the queue begins running. In this
way, all tasks are given equal processing time by the datalogger. The only
exception to this task switching queue is when a measurement task is triggered.
In most instances the processing task and the measurement task should be able
to run in parallel. However, if the datalogger is unable to complete a
measurement when the task sequencer is executing, the task will be interrupted
until the measurement is made.
When running in sequential mode, the datalogger uses a queuing system for
processing tasks similar to the one used in the pipeline mode. The main
difference when running a program in sequential mode is that there is no
prescheduled timing of measurements; instead, all of the instructions are run in
the order they occur in the program. A priority scheme is used to avoid
conflicting use of measurement hardware. In this scheme the main scan has
the highest priority and prevents other sequences from using measurement
hardware until the main scan is completed (including processing). Other tasks,
such as processing from other sequences and communications, can occur while
the main sequence is running. Once the main scan has finished other
sequences have access to measurement hardware with the order of priority
being the background calibration sequence followed by the slow sequences in
the order they are declared in the program. Note that Measurement tasks have
OV-8
CR1000 Overview
priority over other tasks such as processing and communication to allow
accurate timing needed within most measurement instructions, e.g.
integrations.
OV2.4 Data Tables
The CR1000 can store individual measurements or it may use its extensive
processing capabilities to calculate averages, maxima, minima, histograms,
FFTs, etc., on periodic or conditional intervals. Data are stored in tables such
as listed in Table OV2-1. The values to output are selected when running
ShortCut or when writing a datalogger program directly.

OV2.5 PakBus® Communication with the CR1000
The CR1000 uses the PakBus network communications protocol. PakBus
increases the number of communications and networking options available to
the datalogger. In addition to communicating via its RS-232 and/or CS I/O
ports, the CR1000 can also communicate via the digital I/O COM ports.
Some of the advantages of PakBus are:
• Routing – the CR1000 can act as a router, passing on messages intended
for another logger. PakBus supports automatic route detection and
selection.
• Short distance networks with no extra hardware – A CR1000 can talk to
another CR1000 over distances up to 30 feet by connecting 3 wires
between the dataloggers: transmit, receive, and ground. A PC
communicating with one of these loggers (e.g. via a phone modem or RF
to the CS I/O port) can be routed through that datalogger to the other
datalogger.
• Datalogger to datalogger communications – Special PakBus instructions
simplify transferring data between dataloggers for distributed decision
making or control.
All devices that send or receive messages in a PakBus network must have a
unique PakBus Address. The CR1000 default PakBus address is 1. In a
PakBus Network each datalogger must be set to a unique address before it is
installed in the network. To communicate with the CR1000, the PC software
(e.g., LoggerNet) must know the CR1000’s PakBus address.
OV-9
CR1000 Overview
OV2.6 Set up: Device Configuration Utility or Keyboard Display
When you receive a new CR1000 from Campbell Scientific it should be set to
the default PakBus address, 1. If you only have one PakBus datalogger, or will
only communicate with the CR1000 with a direct RS-232 or telephone modem
connection, there may be no need to change the address.
However, if a CR1000 has been in use or someone has borrowed it, you may
need to check what the address is or to set it or some other setting. While there
are a number of ways to do this, the two most basic are to use the Device
Configuration Utility or the Keyboard display.
OV3. Device Configurator
The Device Configuration Utility (DevConfig) sets up dataloggers and
intelligent peripherals before those devices are deployed in the field and before
these devices are added to networks in Campbell Scientific datalogger support
software such as LoggerNet or PC400. Some key features of DevConfig
include:
• DevConfig only supports direct serial connections between the PC and
devices.
• DevConfig can send operating systems to supported device types.
• DevConfig can set datalogger clocks and send program files to
dataloggers.
• DevConfig allows you to determine operating system types and versions
• DevConfig provides a reporting facility where a summary of the current
configuration of a device can be shown on the screen and printed. This
configuration can also be saved to a file and used to restore the settings in
the same or a replacement device.
• Some devices may not support the configuration protocol in DevConfig,
but do allow configurations to be edited through the terminal emulation
screen.
• Help for DevConfig is shown as prompts and explanations on its main
screen. Help for the appropriate settings for a particular device can also be
found in the user’s manual for that device.
• Updates to DevConfig are available from Campbell Scientific's web site.

OV-10
The DevConfig window is divided into two main sections: the device selection
panel on the left side and tabs on the right side. After choosing a device on the
left, you will then have a list of the serial ports (COM1, COM2, etc.) installed
on your PC. You’ll be offered a choice of baud rates only if the device
supports more than one baud rate in its configuration protocol. The page for
CR1000 Overview
each device presents instructions about how to set up the device to
communicate with DevConfig. Different device types will offer one or more
tabs on the right.
When the user presses the Connect button, the device type, serial port, and
baud rate selector controls become disabled and, if DevConfig is able to
connect to the CR1000, the button will change from "Connect" to
"Disconnect". The Display will change to:
OV-11
CR1000 Overview
OV3.2 Deployment Tab
OV3.2.1 Datalogger
The Deployment Tab allows the user to configure the datalogger prior to
deploying it.
Serial Number displays the CR1000 serial number. This setting is set at the
factory and cannot be edited.
OS Version displays the operating system version that is in the CR1000.
Station Name displays the name that is set for this station.
PakBus Address allows you to set the PakBus address of the datalogger. The
allowable range is between 1 and 4094. Each PakBus device should have a
unique PakBus address. Addresses >3999 force other PakBus devices to
respond regardless of their respective PakBus settings. See the PakBus
Networking Guide for more information.
Security:
Up to three levels of security can be set in the datalogger. Level 1 must be set
before Level 2 can be set, and Level 2 must be set before Level 3 can be set. If
a level is set to 0, any level greater than it will also be set to 0 (e.g., if Level 2
is 0, Level 3 is 0). Valid security codes are 1 through 65535 (0 is no security).
Each level must have a unique code. Functions affected by each level of
security are:
Security Password 1 When this level is set, collecting data, setting the
clock, and setting variables in the Public table are unrestricted, requiring no
security code. If the user enters the Security1 code, the datalogger program
can be changed or retrieved or variables can be set in the Status table.
Security Password 2 When this level is set, data collection is
unrestricted, requiring no security code. If the user enters the Security2 code,
the datalogger clock can be changed and variables in the public table can be
changed. If the user enters the Security1 code, non-read-only values in the
status table can be changed and the datalogger program can be changed or
retrieved.
Security Password 3 When this level is set, all communication with the
datalogger is prohibited if no security code is entered. If the user enters the
Security3 code, data can be collected from the datalogger. If the user enters
the Security2 code, data can be collected, public variables can be set, and the
clock can be set. If the user enters the Security 1 code, all functions are
unrestricted.
OV-12
OV3.2.2 Ports Settings
CR1000 Overview
Selected Port specifies the datalogger serial port to which the beacon interval
and hello setting values will be applied.
Beacon Interval sets the interval (in seconds) on which the datalogger will
broadcast beacon messages on the port specified by Selected Port.
Verify Interval specifies the interval (in seconds) at which the datalogger will
expect to have received packets from neighbors on the port specified by
Selected Port. A value of zero (default) indicates that the datalogger has no
neighbor list for this port.
Neighbors List, or perhaps more appropriately thought of as the “expected
neighbors list”, displays the list of addresses that this datalogger expects to find
as neighbors on the port specified by Selected Port. As you select items in this
list, the values of the Begin and End range controls will change to reflect the
selected range. You can add multiple lists of neighbors on the same port.
Begin and End Range are used to enter a range of addresses that can either be
added to or removed from the neighbors list for the port specified by Selected
Port. As you manipulate these controls, the Add range and Remove Range
buttons will be enabled or disabled depending on the relative values in the
controls and whether the range is present in or overlaps with the list of address
ranges already set up. These controls will be disabled if the Verify Interval
value is set to zero.
Add Range will cause the range specified in the Begin and End range to be
added to the list of neighbors to the datalogger on the port specified by
Selected Port. This control will be disabled if the value of the Verify Interval
is zero or if the end range value is less than the begin range value.
OV-13
CR1000 Overview
OV3.2.3 Advanced
Remove Range will remove the range specified by the values of the Begin and
End controls from the list of neighbors to the datalogger on the port specified
by Selected Port. This control will be disabled if the range specified is not
present in the list or if the value of Verify Interval is set to zero.
Help is displayed at the bottom of the Deployment tab. When you’re finished,
you must Apply to send the settings to the datalogger. The Summary window
will appear and you can Save or Print the settings for your records or to use
them as a template for another datalogger.
Cancel causes the datalogger to ignore the changes. Read File gives you the
opportunity to load settings saved previously from this or another similar
datalogger. If you load settings from a file, the changes will not actually be
written to the datalogger until you click Apply.
OV-14
Is Router allows you to control whether the datalogger will act as a PakBus
router.
PakBus Nodes Allocation Specifies the amount of memory that the CR1000
Allocates for maintaining PakBus Routing information. This value represents
roughly the maximum number of PakBus Nodes that the CR1000 will be able
to track in its routing tables.
OV3.3 Logger Control Tab
CR1000 Overview
The clock in the PC and the datalogger will be checked every second and the
difference displayed. The System Clock Setting allows you to configure what
offset, if any, should be used with respect to standard time (Local Daylight
Time or UTC, Greenwich mean time). The value selected for this control will
be remembered between sessions. Clicking the Set Clock Button will
synchronize the station clock to the current computer system time.
Current Program displays the current program known to be running in the
datalogger. This value will be empty if there is no current program.
The Last Compiled field displays the time when the currently running
program was last compiled by the datalogger. As with the Current Program
field, this value will be read from the datalogger if it is available.
Last Compile Results shows the compile results string as reported by the
datalogger.
The Send Program button presents an open file dialogue from which you can
select a program file to be sent to the datalogger. The field above the button
will be updated as the send operation progresses. When the program has been
sent the Current Program, Last Compiled, and Last Compile Results fields will
be filled in.

OV3.4 Send OS Tab - Downloading an Operating System
DevConfig can send operating systems to all Campbell Scientific devices with
flash replaceable operating systems. An example for the CR1000 is shown
below:
The text at right gives the instructions for downloading the OS. Follow these
instructions.
When you click the Start button, DevConfig offers a file open dialog box to
prompt you for the operating system file (*.obj file). When the CR1000 is then
powered-up, DevConfig starts to send the operating system:
When the operating system has been sent, a message dialog will appear similar
to the one shown below:
The information in the dialog helps to corroborate the signature of the
operating system sent. For devices such as the CR10X (especially those with
extended memory) that can take a long time to reset following an OS
download, text warns you against interrupting the memory test.
OV-16
OV3.5 Settings Editor Tab
The CR1000 has a number of properties, referred to as “settings”, some of
which are specific to the PakBus protocol. PakBus is discussed in more detail
in the PakBus Networking Guide
website (www.campbellsci.com).
The Settings Editor tab provides access to most of the PakBus settings,
however, the Deployment tab makes configuring some of these settings a bit
easier.
CR1000 Overview
available from the Campbell Scientific
The top of the Settings Editor is a grid that allows the user to view and edit the
settings for the device. The grid is divided into two columns with the setting
name appearing in the left hand column and the setting value appearing in the
right hand column. You can change the currently selected cell with the mouse
or by using the up arrow and down arrow keys as well as the Page Up and
Page Down keys. If you click in the setting names column, the value cell
associated with that name will automatically be made active. You can edit a
setting by selecting the value, pressing the F2 key or by double clicking on a
value cell with the mouse. The grid will not allow read-only settings to be
edited.
The bottom of the Settings Editor displays help for the setting that has focus on
the top of the screen.
Once you have changed a setting, you can Apply them to the device or
Cancel. These buttons will only become enabled after a setting has been
changed. If the device accepts the settings, a configuration summary dialogue
will be shown that will give the user a chance to save and/or print the settings
for the device:
OV-17
CR1000 Overview
Clicking the Revert to Defaults button on the Settings Editor will send a
command to the device to revert to its factory default settings. The reverted
values will not take effect until the final changes have been applied. This
button will remain disabled if the device does not support the DevConfig
protocol messages.
If, after changing a setting or clicking the Summary button, you clicked Save
on the summary screen to save the configuration, you can use the Read File
button to load those settings. The settings from the saved file are immediately
sent to the device and, if they’re accepted, you can then Apply them.
OV3.6 Terminal Tab
The Terminal tab offers a terminal emulator that can be used to access the
CR1000 Terminal Mode. Press “Enter” several times until the CR1000
terminal mode prompt: “CR1000>“ is returned. Terminal mode commands
consist of a single character and “Enter”. For example, sending an “H” and
“Enter” will return a list of the terminal commands.

OV4. Quick Start Tutorial
OV4.1 Software Products for the CR1000
PC200W Starter Software supports a direct connection between the PC and the
CR1000, and includes Short Cut for Windows (Short Cut) for creating CR1000
programs. PC200W provides basic tools for setting the datalogger’s clock,
sending a program, monitoring sensors, and manually collecting and viewing
data. CR1000 support was added to PC200W in Version 3.0. PC200W is
available at no charge from the Campbell Scientific website.
PC400 Datalogger Support Software (mid-level software) supports a variety of
telecommunication options, manual data collection, and data display. PC400
includes Short Cut and the CRBasic Program Editor for creating CR1000
programs. PC400 does not support combined communication options (e.g.,
phone-to-RF), PakBus® routing, or scheduled data collection.
LoggerNet Datalogger Support Software (full-featured software) supports
combined telecommunication options, data display, and scheduled data
collection. The software includes Short Cut and CRBasic for creating CR1000
programs, and tools for configuring, trouble-shooting, and managing
datalogger networks.
OV4.1.1 Options for Creating CR1000 Programs
1. Short Cut is a program generator that creates a datalogger program in four
easy steps, and a wiring diagram for the sensors. Short Cut supports the
majority of sensors sold by Campbell Scientific, and is recommended for
creating straightforward programs that measure the sensors and store data.
OV-19
CR1000 Overview
OV4.2 Connections to the CR1000
2. The CRBasic Editor is a program editor used to create more complex
CR1000 programs. Short Cut generated programs can be imported into
the CRBasic Editor for adding instructions, or for functionality not
supported by Short Cut.
For those users of CR10X dataloggers who are switching to CR1000
dataloggers, the Transformer Utility can be used to convert a CR10X program
to a CR1000 program, which can be imported into the CRBasic Editor.
Because of differences in program code, not all CR10X programs can be fully
converted by the Transformer. The Transformer Utility is included with
PC400 and LoggerNet software.
Campbell Scientific Power Supplies are described in Section 1.3. When
connecting power to the CR1000, first remove the green power connector from
the CR1000 front panel. Insert the positive 12V lead into the terminal labeled
“12V”, and the ground lead into the terminal labeled “G”. Double-check the
polarity before plugging the green connector into the panel.
Connect the white serial cable (PN 10873, provided) between the port labeled
“RS-232” on the CR1000 and the serial port on the computer. For computers
that have only a USB port, a USB Serial Adaptor (PN 17394 or equivalent) is
required.

OV4.4.1 Creating a CR1000 Program using Short Cut
Objective: Every one second, measure air temperature in degrees C with a
Type T thermocouple, and store one-minute average Battery Voltage, Panel
Temperature, and Thermocouple temperature.
NOTE
A Type T Thermocouple is included with CR1000, packaged
with the screwdriver. The thermocouple consists of a pair of
5-inch wires with blue/red insulation, soldered together at one
end.
Click on the Short Cut button to display the Home screen, as shown below.
OV-22
Each of the four steps has a button with a ? for accessing Help. Use the Help
in conjunction with the steps outlined below:
Step 1: Create a New File
Step 1 is to open a new or existing file. From the Home page, click the New
button. Use the drop-down list box to select the CR1000. Enter a 1 second
Scan Interval and click OK to complete Step 1.
Step 2: Select the Sensors
A Type T thermocouple consists of two wires of dissimilar metals (copper and
constantan) soldered together at one end. The soldered end is the measurement
junction; the junction that is created when the thermocouple is wired to the
CR1000 is the reference junction.
When the two junctions are at different temperatures, a voltage proportional to
the temperature difference is induced into the wires. The thermocouple
measurement requires the reference junction temperature to calculate the
measurement junction temperature.
CR1000 Overview
Step 2 is to select the sensors to be measured. From the Home page, click the
Sensors button. The Sensors worksheet is divided into two sections: the
Available sensors tree and the Selected sensors table, as shown below. The
sensors you want to measure are chosen from the Available sensors tree.
Double click on the Temperature application group to display the available
sensors. Double click on the Wiring Panel Temperature sensor to add it the
selected sensors table. Click OK on the next screen to accept the PTemp_C
label.
Double click on the Type T thermocouple, change the number to 1 and click
OK. On the next screen, make sure Ptemp_C is selected for the Reference
Temperature Measurement, and click OK to accept the Temp_C label.

the diagram. Click the Sensors tab and the Home button to return to the Home
page to continue with Step 3.
Step 3: Output Processing
Step 3 is to define the output processing for the sensor measurements. From
the Home page, click the Output button.
The Output screen has a list of Selected Sensors on the left, and Output Tables
on the right. The default is for two Tables, Table1 and Table2. Both Tables
have a Store Every field and the drop-down list box that are used to set the
interval at which data will be stored.
The objective for this exercise calls for a one-minute output processing. To
remove Table2, Click on the Table2 tab to activate it, and click the Delete
Table button.
The Table Name field is the name that will be used for the Table in which the
output will be stored. Change the default Name of Table1 to OneMin, and
change the interval to 1 minute.
The Selected Sensors list is provided on the left side of the screen. To add a
sensor measurement to the Output Table, highlight a measurement and click
one of the output buttons; e.g., Average. Select the Default, Panel Temp, and

CR1000 Overview
OV6. Specifications
Electrical specifications are valid over a -25° to +50°C range unless otherwise specified; non-condensing environment
required. To maintain electrical specifications, Campbell Scientific recommends recalibrating dataloggers every two years.
PROGRAM EXECUTION RATE
10 ms to 30 min. @ 10 ms increments
ANALOG INPUTS
8 differential (DF) or 16 single-ended (SE) individually
configured. Channel expansion provided by AM16/32
and AM25T multiplexers.
RANGES and RESOLUTION: Basic resolution
(Basic Res) is the A/D resolution of a single
conversion. Resolution of DF measurements
with input reversal is half the Basic Res.
Input DF Basic
Range (mV)
±5000 667 1333
±2500 333 667
±250 33.3 66.7
±25 3.33 6.7
±7.5 1.0 2.0
±2.5 0.33 0.67
1
Range overhead of ~9% exists on all ranges to guarantee
that full-scale values will not cause over-range.
2
Resolution of DF measurements with input reversal.
ACCURACY3:
±(0.06% of reading + offset), 0° to 40°C
±(0.12% of reading + offset), -25° to 50°C
±(0.18% of reading + offset), -55° to 85°C
3
The sensor and measurement noise are not included and
the offsets are the following:
Offset for DF w/input reversal = 1.5·Basic Res + 1.0 µV
Offset for DF w/o input reversal = 3·Basic Res + 2.0 µV
Offset for SE = 3·Basic Res + 3.0 µV
INPUT NOISE VOLTAGE: For DF measurements
with input reversal on ±2.5 mV input range; digital
resolution dominates for higher ranges.
250 µs Integration: 0.34 µV RMS
50/60 Hz Integration: 0.19 µV RMS
MINIMUM TIME BETWEEN VOLTAGE
MEASUREMENTS: Includes the measurement time
and conversion to engineering units. For voltage
measurements, the CR1000 integrates the input
signal for 0.25 ms or a full 16.66 ms or 20 ms line
cycle for 50/60 Hz noise rejection. DF measure-
s with input reversal incorporate two integra-
ment
tions with reversed input polarities to reduce thermal
offset and common mode errors and therefore take
twice as long.
250 µs Analog Integration: ~1 ms SE
1/60 Hz Analog Integration: ~20 ms SE
1/50 Hz Analog Integration: ~25 ms SE
COMMON MODE RANGE: ±5 V
DC COMMON MODE REJECTION: >100 dB
NORMAL MODE REJECTION: 70 dB @ 60 Hz
when using 60 Hz rejection
SUSTAINED INPUT VOLTAGE W/O DAMAGE:
±16 Vdc max.
INPUT CURRENT: ±1 nA typical, ±6 nA max.
@ 50°C; ±90 nA @ 85°C
INPUT RESISTANCE: 20 Gohms

THERMISTOR (for thermocouple measurements):
±0.3°C, -25° to 50°C
±0.8°C, -55° to 85°C (-XT only)
ANALOG OUTPUTS
3 switched voltage, active only during measurement,
one at a time.
RANGE AND RESOLUTION: Voltage outputs programmable between ±2.5 V with 0.67 mV resolution.
ACCURACY: ±(0.06% of setting + 0.8 mV), 0° to 40°C
±(0.12% of setting + 0.8 mV), -25° to 50°C

RESISTANCE MEASUREMENTS
MEASUREMENT TYPES: The CR1000 provides
ratiometric measurements of 4- and 6-wire full
bridges, and 2-, 3-, and 4-wire half bridges.
Precise, dual polarity excitation using any of the
3 switched voltage excitations eliminates dc errors.
RATIO ACCURACY
at least 1000 mV, not including bridge resistor error.
±(0.04% of voltage reading + offset)/V
3
The sensor and measurement noise are not included and
the offsets are the following:
Offset for DF w/input reversal = 1.5·Basic Res + 1.0 µV
Offset for DF w/o input reversal = 3·Basic Res + 2.0 µV
Offset for SE = 3·Basic Res + 3.0 µV
Offset values are reduced by a factor of 2 when
excitation reversal is used.
PERIOD AVERAGING MEASUREMENTS
The average period for a single cycle is determined by
measuring the average duration of a specified number
of cycles. The period resolution is 192 ns divided by
the specified number of cycles to be measured; the
period accuracy is ±(0.01% of reading + resolution).
Any of the 16 SE analog inputs can be used for period
averaging. Signal limiting a
SE analog channel.
