Campbell Scientific CR850 Datalogger F.A.Q.

How do I configure the CR850 datalogger for remote data access?

To configure the CR850 datalogger for remote data access, you need to use LoggerNet software. Connect the datalogger to a PC, open LoggerNet, and configure the IP settings under the 'Setup' tab. Make sure the datalogger is connected to a network via Ethernet or a compatible communication module.

What are the steps to update the firmware on a CR850 datalogger?

To update the firmware, download the latest firmware from the Campbell Scientific website. Connect the datalogger to a PC using an RS-232 cable. Open Device Configuration Utility, select the connected datalogger, and follow the prompts to upload the new firmware.

How can I troubleshoot a CR850 datalogger that is not collecting data?

First, check the power supply to ensure the datalogger is powered. Verify that the program is running by checking the 'Run' status on the datalogger's display. Check sensor connections and ensure that the program is correctly configured for the sensors in use.

How do I perform a factory reset on a CR850 datalogger?

A factory reset can be performed by turning off the datalogger, then holding down the 'Reset' button while turning it back on. Release the button after the display shows the initialization message. Note that this will erase all data and programs.

What maintenance is required to keep a CR850 datalogger in optimal condition?

Regular maintenance includes checking the power supply and battery voltage, ensuring all connections are secure, cleaning the enclosure to prevent dust and debris accumulation, and periodically updating the firmware and software.

How can I extend the battery life of my CR850 datalogger in the field?

To extend battery life, use a low-power mode in the program, decrease the data logging frequency, and ensure that the datalogger is in a power-efficient setup. Additionally, consider using a solar panel or an external power source.

Can I connect multiple sensors to the CR850 datalogger, and how?

Yes, you can connect multiple sensors to the CR850 datalogger. Use the available analog and digital channels, and configure the wiring panel to match the sensor outputs. Ensure the program is correctly set up to read from each sensor.

What should I do if the CR850 datalogger displays a 'Memory Full' error?

If you encounter a 'Memory Full' error, download and archive the data to free up space. You can also increase the memory capacity by changing the data storage configuration or using an external storage device if supported.

How do I set up a CR850 datalogger to send alert notifications?

You can set up alert notifications by using LoggerNet software to configure the datalogger to send emails or text messages. Define the conditions for the alerts in the program, ensuring that the datalogger is connected to a network with internet access.

What are the environmental limits for operating a CR850 datalogger?

The CR850 datalogger can operate in temperatures ranging from -25°C to 50°C. It is designed to be water-resistant but should be housed in a protective enclosure for harsh environments to prevent moisture damage.
