Air T=27.9C, P=100.55kPa, RSSI=78% Zero seemed right on flucuating about 5ppb around zero. I did not set the zero. The span was a little off reading 1.842ppm about 50ppb short. I set the span. I checked it with a scondary CH4 standard determined with an LGR at 4.982ppm CH4. The Li7700 read 5.050. |

| GVSP30 DG002 | 2010-09-21 | Lab none | Installed | Sherman Island | Installed in the box at Sherman Island replacing Frank's diaphragm pump. Sounds real smooth. |
| FMA RMT-200 08-0114 | 2009-03-11 | Lab none | Installed | Sherman Island | Installed at Sherman tower to replace other LGR for mirror cleaning. |

| TR-525I-R1 24875-999 | 2010-09-09 | Lab none | Calibration | Lab none | During the troubleshooting, I ran 16oz (473.3ml) of water through the tipping bucket. According to the manual, this should have resulted in 100 tips. Instead I got 88 tips. I then ran 23.7ml of water that should have resulted in 5 tips and got about 4.5. I then turned the adjustment screws on the bottom two full turns clockwise and got better than five tips. I backed off the screws counter-clockwise a half turn. Now running 473.3ml of water through the tipping bucket results in 99 tips. |
| TR-525I-R1 24875-999 | 2010-09-07 | Lab none | Troubleshooting | Lab none | Troubleshooting the bad final storage values led to the discovery of a bug in the Campbell program on the data logger. If the Totalize function is burried in a "If time is" function, it doesn't work. The follow instructions do not work.

| TR-525I-R1 24875-999 | 2010-09-02 | Vaira Precipitation | Removed | Lab none | This tipping bucket was removed from the Vaira tower to troubleshoot a problem that was causing the total number of tips not to be saved in the final storage location. |
| GVSP30 DG002 | 2010-09-03 | Factory | Repair | Lab none | Returned from factory rebuild. Major kit with bearings, tip seals, pin crank shafts, and crank shaft. From the factory: "The pumps run very hot at 140torr and it's causing some thermal breakdown of the grease and early bearing failure. What we have done is to pack your bearings with grease around an extra 50% by weight and we think this should get you a longer run life between rebuilds. I think we can expect this pump to make the 12 month mark and maybe longer." |
| FGGA 09-0010 | 2010-09-07 | Lab none | Maintenance | Lab none | This analyzer ran in the lab with no flow in slow flow mode and the cell pressure started close to 138Torr and fell slowly. I replaced the internal 2um filter with no improvement. A high flow of lab bench air through the filter before installing seems to have cleaned the down stream side of the filter and did not foul the mirrors.
I bought a new pressure controller from LGR ($720) and installed it. Cell pressure was 138Torr and holding steady with good flow. I had to change the linelock v0 value from 0.215 to 0.225 to get CH4 and H2O to lock. |
| PRB-K Type #8 000000573FAA | 2010-09-03 | Factory | Disposed | Disposed | Report from vendor not repairable:
s/n 000000573FAA Condition on arrival: Visual inspection shows only a missing pin (ID pin, which would not affect probe readings) and a very slight separation between epoxy and the plastic probe head. Ctrl ground and RF ground resistance checks fail, diode 2 resistance passes, but both diode 0 and diode 1 lines indicate an open circuit to one diode in each pair. Only 3 of the expected 5 diode waveforms observed in, probe scans fail (only 2 of 4 segments return values). |

RF Ground and Ctrl Ground pins open circuit, only diode 2 control line passes resistance checks. No diode waveform from +1 diode board, so only segments 3 and 4 readings seem to be okay. |

| FMA RMT-200 08-0114 | 2010-08-06 | Sherman Island | Calibration | Sherman Island | Last calibrated June 2, 2010. Calibrated with 1.8978ppm CH4 God bottle. Before calibration: 1.908+-0.002ppm. After calibration: 1.898+-0.001ppm. |
| LI-6262 IRG3-1079 | 2010-08-04 | Lab none | Calibration | Lab none | I calibrated the LI-6262 with ultra pure N2, zero air and primary standard 370.91ppm CO2 (God bottle). I changed the chemicals for the chopper/reference path and let the 6262 run over night. The N2 and zero air gave very similar results with the zero air possibly being 1ppm CO2 and 14ppm H2O higher than the N2 tank. I filled a new scrub tube with Ascarite II and Drierite and used this to scrub the zero air. I spanned with the 370.91ppm CO2 God bottle. Then I checked a new tank of 400ppm CO2 that will go to Tonzi. This tank checked out at 384.08ppm CO2. |
