Calibration factors are used to correct the O
Menu the instrument generates using its own internal calibration data. The
Calibration Factors menu displays the calibration factors. The screens below
show the calibration factors menu in single mode and dual/auto range
modes.
Normally, the instrument is calibrated automatically using the commands
listed in the Calibration menu described later in this chapter. However, the
instrument can also be calibrated manually using the Calibration Factors
menu.
To manually calibrate the instrument, see "O
Coefficients" below.
