|---|---|---|---|---|---|
| TS01 TS01-001 | 2019-05-30 | Lab none | Installed | Tonzi | Installed near the Floor solar panels looking at the grass to the north. Footprint of about 0.7m x 0.35m diameter |
| LI-7550 AIU-1866 | 2019-05-31 | Factory | Received | Lab none | Received back from Licor. They replaced the RF chip in the power supply. |
| HMP45AC T2130005 | 2019-05-22 | Lab none | Tested | Lab none | I removed the power cord and soldered on an extension cord. Tested in the lab with radiation shields and fans, and compared well with two HMP60s sn L1740398 (Campbell has OK'd this one) and sn G4540023. This sensor is probably ok, but maybe we can test it with a reference AirT/RH sensor from AMP. |
| CS451 70011234 | 2018-12-10 | Lab none | Tested | Lab none | Tested in both air and water in the lab and saw an offset of about +0.975 cm. See RT report "Pressure transducer comparison 12-2018." |
| CS451 70011229 | 2018-12-10 | Lab none | Tested | Lab none | Tested in both air and water in the lab, but saw diurnal fluctuations of only 0.1 cm, not the 5-6 cm we saw in the field. See RT report "Pressure transducer comparison 12-2018." |
| CR1000 47108 | 2019-05-28 | Sherman Barn Data Logger Met | Notes | Sherman Barn Data Logger Met | VX2 may be unreliable. NR01 PRT was drifting constantly until it was re-wired from VX2 to VX3, but that could also have been a wiring issue with another channel. |
| AM16/32B 11662 | 2019-05-28 | Sherman Barn Multiplexer Met | Notes | Sherman Barn Multiplexer Met | Channel 28 and 32 are probably bad (see field notes from SB 2019-04-11). |

| HMP45AC T2130005 | 2019-04-24 | Lab none | Tested | Lab none | Tested overnight in the lab. This sensor has an extension cable soldered on. Didn't see any spikes, and the numbers seem reasonable. However, the control wire seems extraneous--the AirT and RH numbers seem ok even when the control wire is not connected to the datalogger, even though the sensor still has the power control board. More testing needed before we deploy it. |
| HMP45AC U3030046 | 2019-04-24 | Lab none | Tested | Lab none | Tested overnight in the lab. This sensor has an extension cable soldered on. The RH was consistently 5-7% lower than the other 3 sensors (L1740398, T2130005, G4540023). I removed the extension cable, and the numbers were still low. I removed the humidity chip, and it read 150%. When I replaced the humidity chip, the RH was within 2-4% of the other 3 sensors. I added the same extension cable back on, and the numbers became low. This sensor doesn't look consistent and needs more testing before it can be deployed. |

I manually typed in the new coefficients and zero/span values. I saved a config file then opened it in a text editor and changed the calibration dates, standard gas values and WX coefficient. I saved and uploaded this config. This IRGA now has the SD* temperature coefficients and its signal strength was reset at the factory. Our zeros were lower than the factory calibration so I calibrated and saved a new lab calibration config file. |

To connect, Joe had to change the laptop network subnet from 192.168.2.5 to 192.168.1.5 (to match the LI-7700 IP address of 192.168.1.77), even though the subnet mask was 255.255.255.0. We then restarted the instrument and calibrated LI-7700 sn TG1-0421. |

Camilo cleaned the light-source leaf chamber (it wasn't too dusty) and attached it to this console for calibration. We connected the reference and sample inlet to the cal gases with a y-junction. Camilo had checked the zeros using the chemicals last week and found them unsatisfactory (we didn't write them down). We set the zero and the span using cal gas and dewpoint generator. Zero: Cal Gas (zero air), flow at 1SCFH: Before: CO2_S:~-15 CO2_R: ~-15 H2O_S: ~-2 H2O_R: ~-2 After: *All fluctuating around zero. Span with AMP 408.97ppm cal gas, flow at 1SCFH: Before: CO2_R: 413 CO2_S: 423 After: *Fluctuating around 409 Span with 16.0C dew point (2019-03-26), flow at 500 CC/min: Before: H2O_R: 17.50 C H2O_S: 18.52 C After: H2O_R: 16.00 C H2O_S: 16.00 C |

Camilo attached a leaf chamber with a transparent top. He cleaned the chamber, but it wasn't as dusty as he suspected. I changed the time from 15:26 to 13:38. We connected the reference and sample inlet to the cal gases/dewpoint generator with a y-junction. We checked the zero using the chemicals and they seemed ok, but we decided to calibrate zero/spans using the the cal gases and dewpoint generator anyways. Zero: Checked using chemicals: CO2_S: 1.4 CO2_R: -0.1 H2O_S: 0.55 H2O_R: 1.4 Set zero using cal gas: Cal gas = zero air, 1100 psi, 1 SCFH flow Before: CO2_S:-0.9 CO2_R: 4.2 H2O_S: -0.043 H2O_R: -0.592 After: *All fluctuating around zero. Span with 408.97ppm cal gas from AMP: Cal gas = AMP cal gas at 408.97ppm, 800 psi, 1 SCFH flow Before: CO2_R: 408.7 CO2_S: 407.3 After: CO2_R: Did not adjust CO2_S: 409.0 Span with 16.0C dew point: Before: H2O_R: ??
