Detailed 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 data logger. 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, 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.

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.

Downloads

CR3000 OS v.32.05 (4.36 MB) 06-01-2020

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.

  2. Can a CR3000 be added to a MD9 network?

    Yes, but only if all the other data loggers are PakBus devices, such as the CR800, CR850, and CR1000.

  3. Is there any difference in the hardware between a standard temperature range CR3000 and an extended temperature range CR3000?

    No, the hardware is the same. The –XT version has been tested over the range of -40 to +85 degrees Celsius.

  4. Can the CR3000 take input from, and supply power to, different types of sensors that require different voltages?

    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.

  5. What is the common mode voltage for a CR3000?

    The common mode voltage is ±5 V relative to the data logger ground. Both the high and low inputs must be within the common mode range of the data logger.

  6. If multiple CR3000s are linked together via COM1─COM4 ports and configured as neighbors on a PakBus network, what is the best way to synchronize the data loggers so that the time stamps match?

    Synchronizing each data logger to computer time through the data logger 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 data logger and use the GPS instruction to set the data logger clock.

  7. How long will the rechargeable battery base of a CR3000 hold its charge?

    This depends on the average current drain on the battery and whether there is a solar panel or wall charger connected to the charger. For guidance on determining average current drain, see our "Power Supplies" application note.

  8. Does the CR3000 12 Vdc power terminal put out at least 6 mA?

    Yes. The 12 V terminals have a thermal switch that allows 900 mA at 20°C, 650 mA at 50°C, and 360 mA at 85°C.

  9. Can two CR3000s, located close to each other, be directly connected?

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

  10. How is the VX voltage set in a CR3000?

    Bridge measurement instructions [BrFull(), BrFull6W(), BrHalf(), BrHalf3W(), and BrHalf4W()] and the ExciteV() instruction have a parameter called ExmV that is used to specify the voltage used for excitation. This is in the range of ±5000 mV.
