Notes:

1) Added D:\Programs\MD9\MD9jv, made batch file for scheduled task and set up scheduled task: D:\Programs\MD9\MD9jv\Release\MD9_1sec.bat should rename D:\Data\CR10X2_1sec.dat to D:\Data\SI2_1sec_08276.10x

2) Cleaned 40um filter on CH4 inlet

3) Checked Verizon link. Initially clicked connect in VZAccess software. Otherwise seemed okay

4) Arm on the diffuse PAR sensor is going around shading the sensor once every 4:25 minutes. Copied 1 second data file.


Additional Tasks

Water table depths (decimal feet from top of well casing)

Note: Outside wells require regular screwdriver to open cap

inside

Off-south

Off-North

Vegetation height outside of enclosure – 20 samples (inches)

If Swapping Li-7500 Analyzer

Remove SN#

Install SN#

Indicate which ditches are full (copy and paste the red cross on the ditch number)
