6. Balancing Procedures
After sensors installation, click on "F7 - Balancing" button and set balancing parameters. Then click "F9-Next"

6.1 Two-Plane Balancing Procedure
Make step-by-step operations as shown in the table below:
Procedure Step | Two Plane Balancing Window |
---|---|
Run 0 - Start-up without test weight 1. Run the machine at its operating speed (but lower than resonance frequency) 2. Click on F9-Start and measure the vibration level and phase angle in turn without test weight Duration of the measuring process may amount 2-10 sec. | Two plane balancing window ![]() Correction weight mount ![]() |
Run 1 - Test weight in plane 1 3. Stop the machine and mount a test weight of suitable size arbitrarily in plane 1 4. Start up the machine, click on F9-Run and measure the new vibration level and phase angle. Duration of the measuring process may amount 2-10 sec. 5. Stop the machine and remove the test weight | |
Run 2 - Test weight in plane 2 6. Mount a trial weight of suitable size in plane 2 7. Start the machine again, click on F9-Run and measure the vibration level and phase angle once more 8. Stop the machine and remove the test weight | |
Step 4 - Calculation 9. The values of the correction weights and angles required will be calculated automatically and shown in popup form ![]() | |
RunC - Final Check 10. Mount the correction (balance) weights at the positions indicated in popup form at the same radius as the test (trial) weights 11. Start up the machine again and measure the amount of residual unbalance in the rotor, to see how successful the balancing job has been |
6.2 Important Balancing Notes
- Measurements should be carried out with constant speed of rotation of the mechanism
- Correction weights must be installed on the same radius as the trial weights
- Mass of the trial weight is selected so that after its installation phase (> 20-30°) and (20-30%) the amplitude of vibration change significantly
- If changes are too small, the error increases greatly in subsequent calculations
- Conveniently set trial mass at the same place (the same angle) as the phase mark
- After each test run trial mass are removed
- Correction weights set at an angle calculated from the place of trial weight installation in the direction of rotation of the rotor
7. Vibrometer Mode
To select Vibrometer mode click "F5- Vibrometer" button in the main window for two-(one-) plane balancing. To start the measuring process click "F9-Run"

7.1 Measurement Parameters
- V1s (V2s) - summary vibration in plane 1(2) (mean-square)
- V1o (V2o) - vibration in plane 1(2) (first "revolution" harmonic value)
- Phase angle - Phase relationship between vibration and rotation reference
- RPM - Real-time rotational speed measurement
In the right side you can see spectrum window. Measuring data files can be saved in archive.
7.2 Diagnostic Applications
- Unbalance Detection: High 1× vibration indicates mass unbalance requiring correction
- Mechanical Looseness: Broadband vibration with multiple harmonics suggests loose components
- Bearing Defects: High-frequency vibration at bearing characteristic frequencies
- Misalignment: High 2× vibration often indicates shaft misalignment

10. Influence Coefficient Balancing
If you save the results of previous balance runs, you can eliminate the test weight run and balance the machine using its saved coefficients. Select "Secondary" in the "Type of balancing" window and click "F2 Select" button to choose previous machine type from list.

To save coefficients after balancing click "F8-coefficients" in the balancing result pop-up window and then click "F9-Save" button. Input machine type ("Name") and other information in the table.

10.1 Benefits of Influence Coefficients
- Eliminates need for trial weight runs on identical rotors
