The internal lithium battery was low ~0.9V. I replaced it with a "slightly used" Lithium AA battery that was reading 3.2V on the voltmeter. |

Campbell says: Tested unit on bench, unit functioned upon receipt. No problems found, but unit is running OS Rev3. This Rev is suspected to cause random freezes that require disconnection of the lithium battery. The issue has been resolved in the latest CR6 OSes. Updated the logger to latest Rev 7.02. Performed calibration, tested unit in the environmental chamber, and performed final bench test. Replaced the internal lithium battery and included a new USB cable. |

This CR6 became unresponsive for no know reason - only a green light on the RJ45 jack. It was sent to Campbell on RMA 27680 for evaluation and repair. |

I tried to install this CR6 at Tonzi for the new co2 profile on the Tower but it was non-functional. It tested fine in the lab this morning, but was a brick in the field. The green light on the RJ45 jack comes on but no other indication that it has power. |
