2. leave samples in Tonzi
3. soil moisture
4. dendrometer
5. Alexander’s isotope samples

Vaira_Grass Site

1. Fence and gate power: >12 v.
2. Panel and Batteries: 13.4 v; 13.5 amps; 2.0 amps.
3. Reading from Gillsonic screen before downloading data. (The value of H₂O and CO₂ should be in the range of 0 – 5 v.)

1. Reading from Gillsonic screen after downloading data or swaping Li-7500 Analyzer. (Remove SN# 73 ; install SN# 35 )

v	0.01	0.949	CO2	1.571	0.594

1. Check CR23X with two multiplexers

Sys_vot = 2.57
PC_start = 1.4232
Precip multiplier = 0.254, so unit should be in “mm”, but precip output looks too small.
Some wires were on the edge of enclosure door. Not good for a long term.
6. Closed gate and set up fence.

Tonzi_Tower Site

Ted was working on CO2 profile system.
I didn’t download data and do any check, just swap Licor-7500. (Remove SN# 65 ; install SN# 42 ). Looks work well afterwards.

Toniz_Floor Site

1. Fence and gate power: >12 v.
2. Panel and Batteries: 13.6 v; 13.3 amps; 2.2 amps.
3. Reading from Gillsonic screen before downloading data. (The value of H₂O and CO₂ should be in the range of 0 – 5 v.)

1. Readings were OK from Gillsonic screen after downloading data or swaping Li-7500 Analyzer. (Remove SN# 41 ; install SN# 418 )
2. Close gate and set up fence.

• LI-cor 7500 #418 and #35 were repaired in Licor recently.
