2011-07-28

I arrived about 9:00PDT with Dennis, Maribel, Jose and Jaclyn. It was clear, sunny and warm. The rice looks good.

I brought the little screen for the LGR, but did not have the proper VGA cable to use it.

The LGR readings from the CR1000 were:
8:28PST, 25.13C, 137.01Torr, 16.06usec, 10Hz, 1.82ppm

I adjusted the bypass valve to set the pressure at 145.20Torr.

I cut the grass around the box and the tower. I also cut the DO sensor cable. I pulled the DO sensor for repair in the lab.

We tested the three new LED sensors.

We stopped by Frank’s site and I was unable to adjust his LGR pressure, but did return the the system to 10Hz.
