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"

Fig. 7.1 - Vibrometer mode interface

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

8. Charts & Analysis

To view charts of vibration click on "F8-Diagrams". Two kinds of charts are available: "Total vibration" and "Vibration on rotor revolution frequency" (for example, for 3000 rev/min frequency is equal 50Hz)
