I guess with "handing over" you mean "transfer",
But still I do not get your point. As with many manual meters this one has on its display two concentric dial rings, one for aperture, one for shutter-speed, that at metering have to be rotated against each other to yield the apt aperture/shutter-speed pairings.
Only that at your model that rotating against each other is done automatically by built-in motor.
The internal adjustment procedure is called calibration. Finding the calibration procedure for that meter online is highly unlikely. Someone familiar with light meter calibration may provide some insight.
