SERVO-DRIVE flex: Does the refrigerator being filled affect the reference run?

Sometimes we are asked whether the refrigerator needs to be switched on and whether the refrigerator door should already be fully loaded before carrying out a reference run. The answer is no.

The strength of the magnetic lip seal has a significant effect on the reference run. However, this remains unchanged regardless of whether the refrigerator is switched on or off. A vacuum effect does occur after the refrigerator is switched on, but the pressure balances out by itself after a short time (the longest time observed so far is 20 seconds).

Whether or not the refrigerator door is already loaded with food also has no effect on the reference run for SERVO-DRIVE flex.
