Overview

The CR3000 Micrologger® supports complex applications with many sensors. It is fast and powerful enough to handle extended eddy-covariance systems with full energy-balance systems. Multiple CR3000s can be configured as a network or units can be deployed individually.

Designed for stand-alone operation in harsh, remote environments. The CR3000 consists of a compact, integrated package with a built-in power supply, a 128-by-64-pixel backlit graphical or eight-line numeric display, and a 16-character keyboard.

Technical Description

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.

Additional Compatibility Information

Sensors

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.

Measurement & Control Peripherals

The CR3000 is compatible with all of our CDMs (requires an SC-CPI), SDMs, multiplexers, vibrating wire interfaces, terminal input modules, and relays. 

Communications

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, High Data Rate GOES, and Meteosat).

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.

Enclosures

The CR3000 can be housed in an ENC12/14, ENC14/16, ENC16/18, ENC24/30, or ENC24/30S enclosure.

Power Supplies

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.

Software

CRBasic, the CR3000's full programming language,  supports simple or complex programming and many on-board data reduction processes. Compatible software includes:

  • Short Cut
  • PC200W
  • PC400 (version 1.3 or higher)
  • LoggerNet (version 3.2 or higher)
  • RTDAQ (version 1.0 or higher)
  • PConnect (version 3.2 or higher)
  • PConnectCE (version 2.1 or higher)
  • VisualWeather (version 2.0 or higher)

Downloads

CR3000 OS v.32.07 (4.39 MB) 15-05-2024

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.

Watch the Video Tutorial: Sending an OS to a Local Datalogger.

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.

  1. Look for a stamp on top of the battery. The stamp may be in a date format of YYMMDDXX where:

    • YY is the year.
    • MM is the month.
    • DD is the day.
    • XX is the manufacturing plant.

    This indicates the age of the battery.

  2. Yes. Campbell Scientific offers a variety of telecommunications options besides Ethernet, including spread-spectrum radios, licensed radio-frequency modems, cellular modems, satellite transmitters (send data only), land-line phone modems, and other direct connection methods.

  3. Yes. A local PakBus network can be created using a single COM─COM4 serial port on each CR3000.

  4. The base of a CR3000 has four rubber feet. Remove the feet to expose the four holes in the base. Remove the CR3000 datalogger from the base, so that the mount screw (pn 505) can be passed through the base into the grommet (pn 6044) on the enclosure backplate.

  5. The RS-232 port is used for communication with computers, modems, and radios. It is also used for communicating with, and retrieving data from, serial sensors.

    • The RS-232 port on CR3000 and CR5000 dataloggers is electrically isolated.
    • The RS-232 port on the CR800, CR850, and CR1000 is not isolated. For these dataloggers, it may be preferable to connect ac-powered PCs to the CS I/O port instead of the RS-232 port to avoid ground loops on some measurements. 
  6. Use the PreserveVariables() instruction to ensure that all variables reflect the last known value if the datalogger experiences power loss.

  7. The data structure that is used to store data in the datalogger CPU memory cannot be downloaded directly. If the memory of a datalogger is expanded using a CompactFlash card, the native TOB3 file can be downloaded using the Connect | File Control | Retrieve… menu.

  8. The CR3000 can measure analog voltages over the range of ±5 V. Sensors with outputs beyond that range may have their signals conditioned with voltage dividers to be compatible with the CR3000. The CR3000 may supply power to sensors through various channels: voltage and current excitation, continuous analog output, regulated 5 V, unregulated 12 V, and switched 12 V.
