Data storage is managed via an internal memory with options for external storage, ensuring ample capacity for long-term data collection. The CR350 Series is designed with ruggedness in mind, featuring a durable enclosure that protects it from harsh environmental conditions, making it suitable for field deployment in extreme climates. Additionally, it is programmed using Campbell Scientific’s LoggerNet software, which provides a user-friendly interface for configuration, data retrieval, and analysis. The CR350 Series Datalogger is a versatile, reliable solution for precise data monitoring and control in a wide range of applications.

Campbell Scientific CR350 Series Datalogger F.A.Q.

How do I initialize a CR350 datalogger for the first time?

To initialize the CR350 datalogger, connect it to your computer using the appropriate interface cable. Use LoggerNet software to establish communication and configure the datalogger settings through the Setup screen. Ensure that the correct COM port is selected, and follow the on-screen instructions to complete the setup.

What steps should I follow to troubleshoot a CR350 datalogger that isn't recording data?

First, check the power supply and ensure that the datalogger is receiving power. Verify all connections and cables. Use LoggerNet to check the datalogger's status and memory. Ensure that the program is running by checking for any error messages in the LoggerNet Monitor screen. If issues persist, consider re-loading the program and resetting the datalogger.

How can I update the firmware on a CR350 datalogger?

Download the latest firmware from the Campbell Scientific website. Connect the datalogger to your computer and open Device Configuration Utility. Select the CR350 from the device list, then navigate to the Firmware tab. Follow the instructions to browse and upload the new firmware file to the datalogger.

What is the recommended maintenance schedule for a CR350 datalogger?

Regular maintenance should include checking the power supply and battery levels monthly, inspecting connections and cables quarterly, and performing a full system check annually. Clean the enclosure and ensure that all environmental seals are intact to prevent moisture ingress.

How can I retrieve data from a CR350 datalogger?

Data can be retrieved using LoggerNet software. Connect the datalogger to your computer, open LoggerNet, and use the Connect screen to access your device. Use the Retrieve button to download data directly to your computer for analysis.

What should I do if my CR350 datalogger shows a low battery warning?

Replace the batteries with new ones of the recommended type. Ensure that the solar panel or external power source, if being used, is functioning correctly. Check the charging circuitry and connections for any signs of damage or corrosion.

How do I program a simple data collection routine on the CR350 datalogger?

Use the CRBasic Editor in the LoggerNet software to create a program. Define your sensors, measurement intervals, and storage locations. Compile the program to check for errors, then send it to the datalogger using the File Control utility within LoggerNet.

How can I ensure accurate measurements with my CR350 datalogger?

Regularly calibrate your sensors and verify their accuracy against known standards. Ensure that the datalogger is properly grounded and that cables are shielded from electrical interference. Review the program configuration for correct sensor settings and measurement intervals.

What is the best way to protect a CR350 datalogger in harsh environments?

Use an appropriate environmental enclosure to protect the datalogger from moisture, dust, and temperature extremes. Ensure that all cable entries are sealed with grommets or glands. Periodically inspect the enclosure for integrity and clean it as needed.

How do I connect external sensors to the CR350 datalogger?

Identify the sensor types and their corresponding input channels on the CR350. Use the wiring diagrams provided in the sensor manuals to connect them to the datalogger. Configure the datalogger using LoggerNet to recognize and record data from these sensors, ensuring all wiring is secure and correctly grounded.
