Campbell Scientific CR2X Micrologger Datalogger Specification

The Campbell Scientific CR2X Micrologger Datalogger is a versatile and compact data acquisition system designed for a wide range of environmental and industrial applications. It features a 16-bit analog-to-digital converter, providing high-resolution measurements across multiple input channels. The CR2X supports a variety of sensor types, including voltage, current, resistance, and digital sensors, making it adaptable for diverse monitoring needs. This datalogger is equipped with a real-time clock and non-volatile memory, ensuring data integrity and precise time-stamping for all recorded measurements.

The CR2X offers an extensive array of communication options, including RS-232 and CS I/O ports, enabling seamless data retrieval and integration with other devices. It supports direct connection to PCs and remote communication via modems or wireless networks, facilitating flexible data management. The logger is powered by an internal battery, with options for external power sources, guaranteeing reliable operation in remote or off-grid locations.

Programming the CR2X is accomplished through Campbell Scientific's LoggerNet software, which provides an intuitive interface for configuring measurement parameters, data storage, and retrieval routines. The software also supports complex data processing and control functions, enhancing the logger's utility in sophisticated monitoring systems. Additionally, the CR2X is built to withstand harsh environmental conditions, featuring a rugged design that ensures durability and longevity in field applications.

Overall, the Campbell Scientific CR2X Micrologger Datalogger combines robust performance with flexible connectivity and programming options, making it an ideal choice for researchers and engineers seeking reliable data collection solutions in challenging environments.

Campbell Scientific CR2X Micrologger Datalogger F.A.Q.

How do I configure the CR2X Micrologger for data collection?

To configure the CR2X for data collection, use the PC200W software to define your data table settings, set the scan rate, and specify the data storage interval. Transfer the configuration to the CR2X using a serial or USB connection.

What should I do if the CR2X Micrologger is not powering on?

First, check the power supply connections and ensure the battery is charged. Verify that the power switch is in the 'ON' position. If the problem persists, inspect the internal fuses and replace them if necessary.

How can I troubleshoot communication issues with the CR2X?

Check the cable connections and ensure the correct COM port is selected in your software. Test the connection using the Device Configuration Utility, and update the firmware if necessary.

What is the recommended maintenance schedule for the CR2X?

Perform routine checks every six months, including verifying battery voltage, inspecting physical connections, and updating firmware. Clean the enclosure to prevent dust accumulation.

Can the CR2X Micrologger operate in extreme weather conditions?

Yes, the CR2X is designed to operate in a wide range of environmental conditions. However, ensure it is housed in a suitable enclosure to protect against moisture and dust.

How do I download data from the CR2X Micrologger?

Use the PC200W or LoggerNet software to connect to the CR2X. Select the data table from which to download data, and choose the file format for storage on your computer.

What should I do if the CR2X is not recording data?

Ensure that the data table is correctly configured and that sufficient memory is available. Check that sensors are properly connected and functioning. Review program logic for errors.

How can I extend the battery life of my CR2X Micrologger?

To extend battery life, reduce the scan rate and data storage frequency. Consider using a solar panel to recharge the battery, and disconnect any unnecessary peripherals.

What is the procedure for updating the firmware on the CR2X?

Download the latest firmware from the Campbell Scientific website. Connect the CR2X to your computer via USB or serial port and use the Device Configuration Utility to upload the new firmware.

How do I reset the CR2X Micrologger to factory settings?

To reset the CR2X, use the Device Configuration Utility to access the 'Reset' option under the 'Advanced' menu. This will clear all data and settings.
