  • RSK

Each sensor has a calculated set of calibration coefficients stored in the logger. This function adds a calibrations field to the RSK structure, which contains the most current calibration coefficients.

Within the calibrations field there are many other fields:

  • calibrationID : Identifies the calibration.
  • channelOrder: Indicates which channel (sensor) is associated with which coefficients.
  • type: Describes how the coefficients were calculated. The most common is 'factory'. That means RBR calculated the coefficients.
  • tstamp: The time of the calibration calculation in datenum.
  • equation: The calibration equation used to calculate the coefficients.
  • c0...c23, x0...x10, n0...n3: The coefficients values.

RSKtools is not able to recalculate the data if the calibration coefficients are changed. These actions must be performed in Ruskin.
