The device is generally subject to a specific imbalance during operation.
To keep this imbalance as low as possible, all rotating masses in the
system must be balanced as completely as possible.
To ensure optimum mass balancing (imbalance correction) of the device,
identical weights must always be used at both grinding stations
(Ä Chapter 5.10 ‘Mass balance’ on page 47).
The counterweight is used for weight balancing if only one grinding bowl
is inserted with a sample in the p-7 premium line.
