  • Page 75: Master Calibration

    Master Calibration The master calibration determines the coefficients of the master character- istic and stores them in the EEPROM of the probe plug. These coefficients determine the master characteristic, i.e., the correlation between the mea-  surement signal of the probe and the -ferrite content.
  • Page 76 6.4.1 Selecting the Calibration Standards For the user master calibration, the master calibration standard set avail- able from FISCHER as an option should be used! Only in this manner can the specified trueness be ensured during the subsequent measurements. During the user master calibration, the master characteristic can be deter- mined only if suitable calibration standards are used.
