LI-7500A 0042 2019-04-30 Tonzi-Tower Gas Analyzer CO2/H2O Removed Lab none Removed from the Tower for calibration. Replaced by sn 1594. The Tower 7550 box died and was replaced by the Floor 7550 box. No reason to believe the Head was damaged by the box crash but might be worth checking.
LI-7500A 0041 2019-04-30 Tonzi-Floor Gas Analyzer CO2/H2O Removed Lab none Removed from Floor tower for calibration. Not replaced because the Floor 7550 box was moved to the Tower to replace the 7550 box there that died.

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.

Notes: First lab calibration since factory calibration. 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.

LI-7700 TG1-0421 2019-04-11 Bouldin Alfalfa Gas Analyzer CH4 Upgrade Bouldin Alfalfa Gas Analyzer CH4 Upgraded LI-7700 sn TG1-0421 firmware from 1.0.23 to 1.0.27. 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.

LI-6400 PSC-0785 2019-03-25 Lab none Calibration Lab none Camilo Rey-Sanchez and Daphne Szutu

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
LI-6400 PSC-2474 2019-03-25 Lab none Calibration Lab none Camilo Rey-Sanchez and Daphne Szutu

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: ?? C H2O_S:?? C
After: ??
