History for Campbell Sci. CS547A 6494

Rec No.	Date	Loc From	Title	Loc To	Notes
4508	2020-05-29	East End Conductivity Sensor	Calibration	East End Conductivity Sensor	Calibration in the field with DI water (0 mS) and a YSI solution (10,000 uS). Temperature-corrected mS/cm readings from the data logger, where the temperature correction occurs in the data logger program. In DI water: 0.00mS/cm, 22.4C In 10,000 uS calibration soln: 11.3mS/cm, 23.0C Calibration: (Corrected mScm) = 0.8850 * (Sensor mScm)
4310	2019-12-17	Lab none	Installed	East End Conductivity Sensor	Reinstalled at East End after being removed after getting wet ans possibly causing a short circuit. Tested fine in the lab.
4274	2019-12-05	East End Conductivity Sensor	Removed	Lab none	Removed from EE and brought back to the lab for drying and testing. The datalogger door was open when we arrived and the conductivity sensor interface was wet.
4273	2017-09-26	Lab none	Installed	East End Conductivity Sensor	Installed at EE, after I'm assuming it tested fine in the lab.
3073	2017-09-13	East End Conductivity Sensor	Removed	Lab none	Removed from EE because the values were flat.
2382	2015-01-20	Lab none	Installed	East End Conductivity Sensor	Reinstalled after being removed when the scaffolding fell over.
2381	2015-01-05	East End Conductivity Sensor	Removed	Lab none	Removed from the site due to the tower falling over in the wind on 2014-12-30. Likely undamaged.
2376	2014-06-12	Lab none	Installed	East End Conductivity Sensor	Installed on the East End tower with interface sn 3585.
