There may be a problem with the dewpoint generator. |

There might be an issue with the dewpoint generator. |

It didn't make sense for the H2O span to change that much. There might be an issue with the dewpoint generator. |

| CR6 2113 | 2018-02-01 | Lab none | Upgrade | Lab none | Upgraded OS from CR6.Std.03 to CR6.Std.07.02. The older OS has a known issue where the CR6 is unresponsive until the internal lithium battery is removed and reinstalled. After upgrading the OS, I used the "Network Services" tab to enable FTP with the username tower and the usual password. |
