Summary: Delivered DWR batteries, fields drained.

I arrived about 11am. It was clear, sunny and warm with little to no wind. I brought 17 deep cycle batteries for the DWR wetland project. 11 of the batteries went in to the building there six other I kept for use at Tonzi.

The water level on the fields is lower as expect. Bruce said the water would be turned off this week.

The LGR was reporting
11:46PST, 28.00C, 86.52Torr, 13.087usec, 10Hz, 2.175ppm

In low flow the pressure was 107Torr and climbing. I adjusted the bypass valve to bring it up to 147.62Torr. The CR1000 is still getting LGR data at about 5Hz. I’m not sure why, the program is the same except for the SDM call for the 7700. The CR1000 is not reporting missed scans. I’ll have to try to test run the code in the lab.

The 7700 was reporting an RSSI of about 50%. I cleaned the mirrors and it rose to about 70%. The wash reservoir was about half low. I refilled it.

I stopped by Frank’s tower to look at mounts for a GHG1 system. I also checked is LGR pressure. It was reporting 128.30Torr and I adjusted the bypass valve so that it read 135.40Torr.
