Housed in a portable, self-contained package, the CR3000 Micrologger consists of measurement and control electronics, communication ports, 16-character keyboard, display, power supply, and carrying handle. The integrated display shows 8 lines x 21 characters (64 x 128 pixels).
The CR3000 has a choice of three power-supply base options (alkaline, rechargeable, or no battery). Low power consumption allows the Micrologger to operate for extended time periods on its battery recharged with a solar panel—eliminating the need for AC power. It suspends execution when primary power drops below 9.6 V, reducing the possibility of inaccurate measurements.
The on-board operating system includes measurement, processing, and output instructions for programming the datalogger. The programming language, CRBasic, uses a BASIC-like syntax. Measurement instructions specific to bridge configurations, voltage outputs, thermocouples, and pulse/frequency signals are included. Processing instructions support algebraic, statistical, and transcendental functions for on-site processing. Output instructions process data over time and control external devices.

With several channel types, the CR3000 is compatible with nearly every available sensor, including thermocouples, SDI-12 sensors, and 4 to 20 mA sensors. A custom ASIC chip expands its pulse count, control port, and serial communications capabilities. The CR3000's I/O ports can be paired as transmit and receive, allowing serial communications with serial sensors and devices.
The CR3000 is compatible with all of our CDMs (requires an SC-CPI), SDMs, multiplexers, vibrating-wire interfaces, terminal input modules, and relays.
The CR3000 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 its onboard keyboard display, user-supplied 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 CR3000 can be housed in an ENC12/14, ENC14/16, ENC16/18, ENC24/30, or ENC24/30S enclosure.
The CR3000 is typically powered by its on-board alkaline or rechargeable power supply (see Ordering Info). When the rechargeable power supply is used, its internal 7 A h sealed rechargeable battery needs be charged via a vehicle (requires the DCDC18R), solar panel, or ac wall charger.
The CR3000 can also come with a low-profile base that requires a user-supplied dc source. It is preferred when the system’s power consumption needs a larger capacity battery or when it’s advantageous for the Micrologger to be thinner and lighter.
CRBasic, the CR3000's full programming language, supports simple or complex programming and many on-board data reduction processes. Compatible software includes:
Execution of this download installs the CR3000 Operating System and Compiler on your computer. It also updates the CR3000 support files for the CRBasic Editor.
Note: The Device Configuration Utility is used to upload the included operating system to the datalogger.
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.

Look for a stamp on top of the battery. The stamp may be in a date format of YYMMDDXX where:
This indicates the age of the battery.
A practical maximum is to connect one multiplexer per every two control terminals on the data logger. Control terminals can be shared between multiplexers to increase the number of connected multiplexers. Sharing terminals, however, requires more complex wiring and programming. Users who would like to connect more than one multiplexer per every two control terminals are advised to contact a sales or support engineer at Campbell Scientific for assistance.
Yes, but only if all the other data loggers are PakBus devices, such as the CR800, CR850, and CR1000.
Yes, using the following steps:
Synchronizing each datalogger to computer time through the datalogger support software is the easiest way and will work well for many applications. In LoggerNet an automated clock check may be set up that resynchronizes whenever a user-defined clock deviation is detected. In high-speed applications it may be desirable to attach a GPS device to each datalogger and use the GPS instruction to set the datalogger clock.
Yes. A local PakBus network can be created using a single COM─COM4 serial port on each CR3000.
No, the hardware is the same. The –XT version has been tested over the range of -40 to +85 degrees Celsius.
