The CR1000 is our most widely used datalogger. It can be used in a broad range of measurement and control functions. Rugged enough for extreme conditions and reliable enough for remote environments, it is also robust enough for complex configurations.
The CR1000 builds on the foundation of our CR10X dataloggers, and has already been put to use all over the world. Increased memory and more measurement channels make it a powerful core component for your data-acquisition system.
The CR1000 consists of a measurement and control module and a wiring panel. This datalogger uses an external keyboard/display and power supply. Low power consumption allows the CR1000 to operate for extended time periods on a battery recharged with a solar panel—eliminating the need for AC power. The CR1000 suspends execution when primary power drops below 9.6 V, reducing the possibility of inaccurate measurements.
The CR1000's module measures sensors, drives direct communications and telecommunications, reduces data, controls external devices, and stores data and programs in on-board, non-volatile storage. The electronics are RF shielded and glitch protected by the sealed, stainless-steel canister. A battery-backed clock assures accurate timekeeping. The module can simultaneously provide measurement and communication functions. The on-board, BASIC-like programming language supports data processing and analysis routines.
The CR1000WP is a black, anodized aluminum wiring panel that is compatible with all CR1000 modules. The wiring panel includes switchable 12 V, redistributed analog grounds (dispersed among analog channels rather than grouped), unpluggable terminal block for 12 V connections, gas-tube spark gaps, and 12 V supply on pin 8 to power our COM-series phone modems and other peripherals. The control module easily disconnects from the wiring panel allowing field replacement without rewiring the sensors.
Originally, the standard CR1000 had 2 MB of data/program storage, and an optional version, the CR1000-4M, had 4 MB of memory. In September 2007, the standard CR1000 started having 4 MB of memory, making the CR1000-4M obsolete. Dataloggers that have a module with a serial number greater than or equal to 11832 will have a 4 MB memory. The 4 MB dataloggers will also have a sticker on the canister stating “4M Memory”.
1Certain digital ports can be used to count switch closures.
2I/O ports can be paired as transmit and receive for measuring smart serial sensors.
With several channel types, the CR1000 is compatible with nearly every available sensor, including thermocouples, SDI-12 sensors, and 4 to 20 mA sensors (via a terminal input module, such as the CURS100). A custom ASIC chip expands its pulse count, control port, and serial communications capabilities. The CR1000's I/O ports can be paired as transmit and receive, allowing serial communications with serial sensors and devices.
The CR1000 is compatible with all of our CDMs (requires an SC-CPI), SDMs, multiplexers, vibrating-wire interfaces, terminal input modules, and relays.
The CR1000 communicates with a PC via direct connect, Ethernet interfaces, multidrop modems, short-haul modems, phone modems (land line, digital cellular, and voice-synthesized), RF telemetry, and satellite transmitters (Argos, Iridium, and Inmarsat).
Data can be viewed on the CR1000KD Keyboard Display, the CD100 Mountable Display with Keyboard, an iOS or Android device (requires LoggerLink), CD295 DataView II Display, or a user-supplied PDA (PConnect or PConnectCE software required).
Compatible external data storage devices are the CFM100, NL115, and SC115.
The CR1000 and its power supply can be housed in any of our standard enclosures.
Any 12 Vdc source can power the CR1000 datalogger. Power supplies commonly used with the CR1000 are the BPALK, PS150, and PS200. The BPALK provides eight non-rechargeable D-cell alkaline batteries with a 7.5 Ah rating at 20°C.
Both the PS150 and PS200 consist of a sealed rechargeable 7 Ah battery and a charging regulator. Their battery should be connected to a charging source (either a wall charger or solar panel). These two power supplies differ in their charging regulator. The PS150 has a standard regulator and the PS200 has a micro-controller-based smart regulator. The PS200's regulator provides two-step constant voltage charging and temperature compensation that optimize battery charging and increases the battery’s life.
Also available are the BP12 and BP24 battery packs, which provide nominal ratings of 12 and 24 Ah, respectively. These batteries should be connected to a regulated charging source (e.g., a CH100 or CH200 connected to a unregulated solar panel or wall charger).
CRBasic, the CR1000's full programming language, supports simple or complex programming and many onboard data reduction processes. Compatible software includes:
Execution of this download installs the CR1000 Operating System and Compiler on your computer. It also updates the CR1000 support files for the CRBasic Editor.
Note: This OS has crossed the 2 Meg CR1000 size limit for remote download. The OS must be downloaded to the 2 Meg CR1000 via direct connect with the Device Configuration Utility. All OS download methods are supported by the 4 Meg CR1000.
Upgrading from versions prior to version 28 of the Operating System will reset the datalogger’s CPU drive. This is due to a change in the format of the file system from FAT16 to FAT32. In order for the datalogger to operate correctly, as part of the upgrade, the CPU drive is formatted to FAT32. Any programs stored and running from the CPU drive will be lost. It is not recommended to update the datalogger’s Operating System over a remote connection where program control regulates the communication equipment (turning it on or off, etc.). In these cases, an on-site visit and a backup using DevConfig’s backup utility is necessary to update the datalogger’s Operating System.
In all cases where the datalogger is being updated from an Operating System prior to 28, the use of DevConfig’s backup utility is recommended due to the CPU drive being formatted using the new FAT32 format.

Use the PreserveVariables() instruction to ensure that all variables reflect the last known value if the datalogger experiences power loss.
Yes. The CR1000 could be set up as a SDI-12 sensor using the SDI12SensorSetup() instruction. Alternatively, the CR1000 could be set up to perform serial communications with the CR3000 by connecting a COM1─COM4 port pair and ground from one datalogger to a COM1─COM4 port pair and ground on the other datalogger. The COM1─COM4 port lines need to cross RX to TX and vice versa.
Yes. Create a multidrop network with an MD485 between the CR5000, the CR1000, and the digital modem. See the “Digital Cellular Modem to MD485 Network” appendix item in the MD485 instruction manual.
For the CR1000, to get continuous analog outputs, an SDM-AO4A (4-channels, non-isolated, voltage only) or an SDM-CVO4 (4-channels, isolated, voltage or current) is needed. Multiples of these devices can be used to get more outputs. For single channels of output, some third-party devices can be used.
The advantage of the BrHalf4W circuit is that the effect of lead resistance is measured and compensated for. The disadvantage is that it requires two differential (four single-ended) voltage input channels and four wires to the sensor.
Some sensors have four wires and are sensitive enough that the lead resistance would cause too great an error.
The BrHalf, a two-wire measurement, does not compensate for lead resistance.
The BrHalf3W lead compensation assumes that both leads are of the same resistance.
Either the PortSet() or the WriteIO() instruction can be used to open and close the 7321 relay. These instructions are commonly used in conjunction with an IfThen/EndIf construction.
In this first example, the program closes the relay at the top of a 60 second interval and then opens the relay after ten seconds:
If IfTime (0,60,Sec) Then
ElseIf IfTime (10,60,Sec) Then
In this second example, the WriteIO() instruction is used to close the 7321 relay based on the measured panel temperature:
If PTemp > 25 Then
The lithium battery voltage is measured by the datalogger once per day, and the value is held in the Status table when it is running normally. The voltage is normally extremely stable if the datalogger is powered from another source and its temperature is stable. A new battery supplies approximately 3.6 Vdc; it should be replaced when its reading is at or below 2.7 Vdc.
The lithium battery voltage is also read when the datalogger is reset or its program is recompiled.
