•
Count direction: It can be chosen between clockwise and counterclockwise. The reflection
mark always references the position 0°. The count direction on the balancing layer is al-
ways from the perspective of the speed sensor, thus with view on the reflection mark.
•
Use fixed positions: If masses can only be applied to dedicated positions, this option must
be checked. The positions must be distributed equidistantly over the whole balancing layer.
•
Number of fixed positions: The number of fixed positions must be entered here, if the option
“use fixed positions” is activated.
•
Rotor mass: The mass of the rotor in gram. The information is required to calculate the
quality level after the balancing according to DIN ISO 21940-11:2017-03.
•
Radius of mass positions: For the calculation of the quality level according to DIN ISO
21940-11:2017-03 the radius of mass positions is also required. It is the distance of the
mass position to the centre of the balancing layer. On these positions the test masses as
well as the balancing masses must be applied.
6.3.2. Origin Measurement
The origin measurement can be started by clicking on continue, if all parameters are set up. It
will be first waited until the speed is in the valid range. If this is the case the actual measure-
ment starts automatically and also stops automatically if the required number of revolutions
are reached.
6.3.3. Test Measurement
A calibration of the system is required to calculate the correct balancing masses. For a balanc-
ing in one layer, a test measurement with a test mass on this layer is required. If the balancing
is done in two layers, an additional test measurement with a test mass on the second layer
must be done. The test masses must be removed from the corresponding layer after each test
measurement. The example in Picture 24 shows an application of a test mass of 80 g at posi-
tion 60°. After the machine is at the expected target speed, the measurement can be started.
If the balancing is done in two layers, the mass can be removed from the first layer and applied
to the second layer.

6.3.4. Validation Measurement
The balancing masses to correct the initial imbalance are calculated after the successful test
measurement.
If the option “use fixed positions” was activated, two masses per layer are cal-
culated. Picture 25 shows an exemplary calculation of required balancing masses to reduce
the initial imbalance. If it is not possible to apply the exact masses to the locations, the actually
applied masses can be entered.
