DETERMINE NO-LOAD POWER
Clamp the milling cup – still without milling material and milling medium – firmly in the machine.
Start the machine. The process now following lasts approx. 45 sec. During this time the PM400
determines the no-load power with empty milling cups at the subsequent operating speed.
After determining the no-load power the PM400 stops automatically and you are asked to fill in the
milling material and milling balls.
Determine the increased weight of the milling cup filled with milling material and milling medium.
Please note that balancing of the PM400 must be corrected accordingly.
After pressing the Start button again you are asked to decide on “MEASURE” or “SPECIFY” the power.
MEASURE
After determining the no-load power only the additional power put into the milling cup through
movement of the balls and milling material during the milling time is determined.
SPECIFY

longer possible. The machine stops when the preset power has been put in.
