Basic Calibration Process

When calibrating with a Campbell Scientific datalogger, known and measured values are given as inputs. The outputs of the calibration then become the new values for the multiplier and offset variables in the CRBasic program. If needed, these calculated multipliers and offsets can be permanently stored and automatically reloaded upon program restart (such as when a power-cycle occurs on the datalogger). The datalogger makes use of a calibration file (*.cal) to store these calibration values and load them as desired. This can be done at datalogger power-up or at other times designated within the datalogger program.

To evaluate calibration histories, a final storage output table can be configured to store the results of calibrations that have been performed, and the date and time at which those calibrations were performed. This data is separate from the calibration file and forms a permanent history of calibration constants used within the program.
