Detailed Description

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”.

Additional Compatibility Information

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.

Measurement & Control Peripherals

The CR1000 is compatible with all of our CDMs (requires an SC-CPI), SDMs, multiplexers, vibrating-wire interfaces, terminal input modules, and relays. 

Communications

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.

Enclosures

The CR1000 and its power supply can be housed in any of our standard enclosures. 

Power

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).

Downloads

CR1000 OS v.32.05 (4.57 MB) 06-01-2020

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.

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.

Frequently Asked Questions

Number of FAQs related to CR1000: 167

Expand AllCollapse All

  1. The potential transformer and the current transformer provide differential outputs that have galvanic isolation from the voltage and current in the circuit they are measuring. However, there is no need to run the outputs of these transformers into differential inputs of the data logger and unnecessarily consume additional data logger channels. We conducted extensive testing for noise immunity, for inaccuracies from ground loops, and more before concluding that single-ended measurements in the ACPower() instruction have the same performance as differential measurements would provide. Please note that as a result of the galvanic isolation of the potential transformer and current transformer, the data logger ground is NOT connected to the ground of the circuit they are measuring.

    Said differently, you can connect differential outputs of a sensor to single-ended inputs of the data logger. However, doing so creates the possibility of poor common-mode noise rejection in the data logger and the possibility of introducing inaccuracies from ground loops between the sensor and the data logger. Note that in this application, the transformer isolation of the potential transformer and the current transformer eliminates these concerns.

    Simply connect one of the potential transformer secondary wires and one of the current transformer secondary wires to the data logger ground. Which wire in either case makes a difference, as the phase information allows the measurement of power flowing in either direction. If you measure negative real power when it should be positive, then reverse the secondary wires of the potential transformer where they connect to the data logger. Alternatively, you can reverse the secondary wires on the current transformer, but don't reverse both pairs of wires.

  2. Recalibration of the CR1000 is recommended every three years.

  3. 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

  4. If PPP is enabled in the settings, the data logger effectively reviews what it should be doing with the PPP connection every second. If PPPClose was called at some point, the message “user closed ppp” is displayed in the trace log, every second or so. This means that the data logger checked what it should be doing and found that it should be closed. (It does not mean that PPPClose was called at that time.)

  5. Use the PreserveVariables() instruction to ensure that all variables reflect the last known value if the data logger experiences power loss.

  6. Only one CWB100 can be connected to each odd channel control port. For the CR800 and CR850, this relates to two total units—one on C1 and one on C3. On the CR1000 and CR3000, this amounts to four total units.

    Putting more than one CWB100 on a data logger will NOT speed up sensor data collection. Only one CWB100 should be accessed at any given time, or the devices will interfere with each other. If multiple CWB100 devices are connected to a single data logger, the data collection schedules for the CWB100 devices should be staggered. Sufficient time should be built in to allow each base unit to collect data from all of the remote sensors associated with it and to allow for any needed retries.

  7. Pass-code lockouts (historically known as security codes) are the oldest method of securing a Campbell Scientific data logger. This method provides a level of security, mainly for PakBus communications. However, someone with physical access to a data logger or telecommunications hardware may be able to overcome the five-digit pass-code lockouts. To further secure PakBus communications, use the PakBus Encryption Key and PakBus/TCP password. 

  8. The number of data tables that can be defined is limited to 30.
  9. The CR1000 does not have any continuous analog outputs. It has three excitation channels that are momentarily turned on during measurements. Use the SDM-AO4A for proportional control or driving strip charts.
