Summary: Install LI7700 digital acquisition, swap Gill PCI, swap CR1000, swap LI7500 for calibration.

Mayberry
2/3/2011

I arrived about 8:15am. There was a little frost in protected spots, but no fog and warming quickly. There were some high thin clouds and only a breath of wind from the east. There was a huge flock of snow geese and from greater white-fronted geese on the fields along the entrance road.

I hung the new LI7700 on the tower with washer box. I swapped out the CR1000 for a new CR1000 and added a Quatech RS422 to 232 converter to talk to the sonic. I did not remove the Gill PCI, but it is now idle unpowered. I connected the enternet cable from the LI7700 directly to the CR1000. Data on the CR1000 looked good. The LI7700 had an RSSI of 89%.

I swapped the LI7500 for calibration. Sn 0042 went on and sn 0073 came off.

I collected data from the CR23x.

The solar charge controller read 14.7V, 9.1 A solar, and 1.3 A load before I left. I think this is about 0.8A less than when the LI7550 interface box, and possibly the Gill PCI were running previously.

I left for Ione about 9:30.
