Summary: Calibrated 7700, water not running - left message with Jim, 7500 AGC reading 0.0?

West Pond
2013-02-21

I arrived about 10am with Cove. It was clear, sunny and cool. There was a breeze from the north, but at the tower we were shielded from the wind chill.

The water inlets were not running and the water level was just below the CO2 sensor, but the bottom of the DO was still in the water. I left a message with Jim about the water flow.

We calibrated the 7700 sn 0223. We cleaned the mirror raising the RSSI from 46 to 67. This 7700 was also fairly close with offsets of about +16ppb at zero and about -6ppb for span.

The LI7500 was reporting an AGC of 0.0 which seemed strange. However the CO2 and H2O seemed okay and the AGC went to 100 when we blocked the path, so it was responding. I’ll ask Licor about that.
