CR300 Series OS 6.00
Updated: 08-09-2017

  1. (URGENT) An issue was found in the previous operating systems that could cause the datalogger to become unresponsive in some systems after 50 days. This operating system resolves that issue. It is highly recommended that all CR300s and CR310s be upgraded to this operating system.
  2. (WARNING) Upgrading the Operating System could reset all CR300 settings back to factory defaults. Sending this Operating System remotely can be done but is not recommended. To restore settings after the update, it is recommended that a backup be made of the current datalogger settings or take programmatic measures to ensure your settings can be restored. This can be done using Device Configuration Utility’s (DevConfig) backup utility or the CRBasic instruction SetSetting()Watch the Video Tutorial: Sending an OS to a Local Datalogger.
