Arrived about noon time with Jaclyn. Clear, sunny, light breeze. Pepper weed flowers mostly brown. From the bridge on the way home, northern 1/3 of field seemed wet with water in first ditch rest of the field and ditches are dry though.

Goal was to swap sonic on secondary tower. New WMP sn 074417 has Ts averaging problem, replacing with old model sn 000019, but cable connector is different and I did not bring old style cable. Will replace next week - secondary tower off line until then.

Checked LRG:
1.86ppm
30.9C
16.6 usec
122 Torr

Cleaned filters - there was a bee at 40um. Exterior 2um filter seems clear. Restarted at 160Torr but jumped to 130Torr after a few seconds. Flow was 31 LPM at this point. I adjusted the bypass value and set pressure at 142.6 Torr. Flow was 35 LPM at this setting. Still not the 50LPM expected. Will check with a scroll pump in the lab - need fittings.

Copied data. CR10x2 did not report data since 6/16, USB serial port hung up. Unplugging/replugging USB serial adapter fixed it.

Swapped card on CR1000.

Data from June 4th 1:30pm to June 26th 1pm on Data PC.
