Rec No.	Date	Loc From	Title	Loc To	Notes
5172	2021-03-10	Lab none	Damaged	Lab none	Accidentally fried this sensor when I plugged the power strip in reverse polarity. When Joe tried later to plug the sensor in, it browned out the whole sensor.
4954	2020-11-12	Sherman Wetland-Temp1 Barometer	Removed	Lab none	Removed with decommissioning of Sherman Wetland Temp tower. Brought back to the lab for cleanup.
4336	2020-01-30	East Pond Barometer	Moved	Sherman Wetland-Temp1 Barometer	Removed with the decommissioning of the EP tower and installed at the new SW Temporary site 1250m upwind of the Permanent Tower.
3405	2018-04-17	Lab none	Installed	East Pond Barometer	Installed at EP tower as part of initial site set up.
3329	2018-02-15	Lab none	Tested	Lab none	The sensor tested successfully with a sample CR1000 program sent from Campbell. The sensor works as a single-ended measurement, but not as a differential measurement (I'm not sure why). I had only tested as a differential measurement previously.
3199	2017-11-16	Lab none	Tested	Lab none	Consistently tested as 0V out. Vin was 12V and it was wired correctly. Looking at recent TW data (where this sensor was last) from Mar/Apr 2017, pressure data seems reasonable. Not sure where/why/when it got damaged.
2709	2017-04-04	Twitchell Rice Barometer	Removed	Lab none	Removed with Twitchell Rice tower decommissioning.
1343	2014-06-12	Lab none	Installed	Twitchell Rice Barometer	Installed at the rice to replace sn E1330045.
