2. Changing the correction mode (Tools menu / Machine setup)
The correction mode describes how the balancing weight is attached
to the rotor. Normally the correction mode is set to 'Free & add', i.e.
the weight can have any mass and be placed at any angular position.
• Press the MENU button in the data screen, and click on "Tools" (see
below)*.
The following correction modes are available additionally:
– Fixed location
– Fixed weight
– Measuring tape
The following can be selected for each correction mode:
- Add weight on rotor, or
- Remove weight from rotor
For 2-plane balancing the correction mode can be configured sepa-
rately for each plane.
2.1 Fixed location
To attach the balancing weight only at specific positions on the ro-
tor (e.g. on the blade of a ventilator), select the "Fixed location"
correction mode. Then enter the "Number of locations" on the rotor.
VIBXPERT calculates two masses which are to be placed at two of the
specified positions. Position or blade 1 corresponds to the 0° position
and should be selected as a reference mark for the trigger. In the data
screen, the angular position is displayed for each fixed location.
