Mayberry
2011-06-30

I arrived about 12:30 with Jaclyn, Dennis, Jose, Emily and Maribel. It was hot and sunny with a little breeze gradually getting stronger.

The LI7700 reservoir was empty again. I refilled it.

I worked on calibrating the LI7700. The power cords for the LI7700 and LI7550 are different than the LI7500s. The LI7700 RSSI was about 35 when I arrived and was close to 80 after cleaning with alcohol. I removed the solar shield and installed the calibration hood. I was able to connect to the LI7700 through the LI7550 using Ethernet. I changed the wash cycle from 20sec spray rechecked every 15min to a 10sec spray rechecked every 3hr as suggested by Liukang. I flowed zero air from a small transfer tank at about 400psi. The LI7700 reported 0ppm CH4. I then flowed 1.976ppm secondary standard from the tank that used to be at Sherman. The LI7700 reported 1.976ppm CH4. Because the LI7700 seemed to be right on I did not to a formal calibration.

I checked the autocam and it was still running.

Some more bird poop on the solar panels.
