Equipment and Calibration History

History for Campbell Sci. CS547A 7157

Rec No.	Date	Loc From	Title	Loc To	Notes
5032	2020-12-09	Lab none	Installed	Mayberry Conductivity Sensor A	Installed at MB with interface sn 547-02 to replace sn 5688, which was brought back to the lab for testing.
4980	2020-11-19	Mayberry	Removed	Lab none	Removed sensor and factory A547 interface from MB after concluding the conductivity sensor comparison. Brought back to the lab to test a homemade A547 board.
4943	2020-11-03	Sherman Wetland Conductivity Sensor	Moved	Mayberry none	Moved from SW to MB for a temporary intercomparison because there was no water at the SW tower and sn 5688 at MB was giving high temp number
4499	2020-05-26	Sherman Wetland Conductivity Sensor	Calibration	Sherman Wetland Conductivity Sensor	Cleaned and calibrated in the field with DI water (0 mS) and a YSI solution (10,000 uS). These are the temperature-corrected mScm readings from the datalogger, where the temperature correction occurs in the datalogger program. In DI water: 0.56 mScm In 10,000 uS calibration soln: 10.6 mScm Calibration: (Corrected mScm) = 0.996 * (Sensor mScm) - 0.558
2646	2016-05-24	Lab none	Installed	Sherman Wetland Conductivity Sensor	Installed at Sherman Wetland
