Summary: Installed railing and autocam, swapped 12VDC power strip in the data logger box, could not fix SOS problem - maybe wiring, collected all data, water flowing.

West Pond
2012-07-05

I arrived about 12:30PDT. Sara and Carina dropped me off while they went to Twitchell and then the Corn site. It was clear, sunny and hot with a gusty wind from the west. The water seems to be flowing at full flow in both ponds. The water level is higher but the upper DO sensor is still out of the water.

I attached a railing to the top south side of the scaffolding and mounted an autocam to the railing. I took down the power while I replaced the power strip with a new larger one and reorganized some of the power lines.

The LI7700 RSSI was 30 before cleaning and 74 afterwards.

I collected data and swapped the USB drive.

I checked the LI7550 and sonic settings. They all seemed to be in agreement running on a 0-5V range. I changed the range to -5 to +5V range. On this setting U seemed to be maxing out. I changed the LI7550 to record just the voltages (span = 1, offset = 0). And I changed the sonic to output -2.5 to +2.5V. I think there might be a wiring problem in the sonic connector. I can try to fix that next week.
