testing the soil system. placing the theta probes in water

sn 54/015: 1.1381 v, zero: 0.00318
sn 54/016: 1.1403 v, zero: -0.00067
sn 54/017: 1.1294 v, zero: -0.00101
sn 54/019: 1.1317 v, zero: -0.000034
sn 54/020: 1.1367 v, zero: -0.00101

Preparation of LI-7500, sn 0042

Zero with N2 was 2.0, after running several weeks in the lab

Cal gas 402.25 read 411.1 ppm at P=101.31 kPa and T 23.17 C.

Licor Dewpoint sensor read 14.57 Tdew. Vaisala standare read 13.9 C. We are using the Vaisala as the standard for the experiment.


Rezeroed and spanned

D/A #1, H2O mmol m-3
0v=0
5 v=1000

D/A #2, CO2 mmol m-3
0v=13 mmol m-3
5v=20 mmol m-3

(note, prior tests in Oregon, showed these values remained on scale).
