CS547A 5688	2013-10-22	Lab none	Tested	Lab none	I (Sara Knox) tested the probe in the lab since it was giving bad readings in the field. Temperatures were negative and conductivity values were off as well. I called campbell and they said it could be water intrusion that damaged the thermistor (although the resistance across the red & green wires was giving plausible values...). The guy at campbell said we could send it in, but that it would cost at least 100$ to fix it plus there is no guarantee that they could fix it. He suggested buying a new one.

GMP221 H1310020	2013-07-23	Lab none	Tested	Disposed	I (Sara Knox) tested the probe in the lab to try to figure out what was wrong with it. It still maxed out at 5000 mV and the lights on the circuit board were flashing red and green. I took it out of the teflon tubing to inspect the probe for water damage - sure enough it was all corroded. I think its dead Jim.

CNR1 020476	2013-06-27	Twitchell Alfalfa	Removed	Lab none	Pulled the CNR1 off the Twitchell Alfalfa tower. Was being tested alongside the NR01 at the site. Now in the lab.
FMA RMT-200 08-0114	2013-06-20	Lab none	Maintenance	Lab none	This analyzer refused to boot in the field and was swapped out by Cove. In the lab it continued to hang in booting. After trying a few things (pressing f2, etc), pressing esc at the "System Bios Configuration" screen allowed me to choose between two versions of the OS: Fedora Core [version #] legacy.nptlcustom Fedora Core [version #] legacy.nptl Selecting the non-custom one booted to a command prompt where I could log in as root/3456789. However the screen kept flickering out giving me about 1 second to type then going black for about 5 seconds an not taking input. The df command should that the disk was 100% used. I navigated to /home/lgr/data and deleted some files from 2009 and then I rebooted. On reboot the LGR ran normally. I then entered the service area in the setup window with the ICOService password. From the service area I deleted all files from 2008, 2009, 2010, 2011, and 2012. Afterwards the disk usage was 23% used. Should be good for a few more years.

FMA RMT-200 08-0114	2013-06-18	Sherman Island	Removed	Lab none	Removed from Sherman Island by Cove. The external pump was off and the LGR refused to boot. It was replaced by sn 05-0010
CNR1 020476	2013-06-18	Lab none	Installed	Twitchell Alfalfa	Installed on the radiation post at the Twitchell Alfalfa for a cross comparison with the Hukseflux NR01 sn 1570
CNR1 020476	2013-06-13	Twitchell Alfalfa	Removed	Lab none	Removed from the radiation post at the Twitchell Alfalfa field due to bad readings on all channels. Later determined that the SWin channel was accidentally put into the second COM channel on the multiplexor.
