3.3 Calibration Procedure
A calibration procedure consists of a white measurement
followed by a black measurement. The instrument notifies you
when a calibration is required.
NOTE: The instrument must be calibrated with the target window
removed when using the instrument with the shoe extended
(unlatched).
To perform a calibration:
1.
At the Calibration menu screen, position the target window
over the white ceramic disk as previously explained.
