Portable field balancer "Balanset-1A"
Balanset-1A is portable dynamic balancer used to balance rigid rotors in their own bearings (in-situ) or as measuring system in the balancing machines. It provide single- and two-plane dynamic balancing services for fans, grinding wheels, spindles, crushers, pumps and other rotating machinery. Balancing software provides the correct balancing solution for single-plane and two-plane balancing automatically.
2. Prepare to work. Software and hardware setup for two-plane balancing.
2.1 Driver installation
2.2 Sensor installation

Then make step-by-step operations as shown in the Table 1 below.
|Table 1. Step-by-step operations
Run 0 - Start-up without test weight.
2. Run the machine at its operating speed (be sure that operating speed is far from resonance frequency of construction)
3. Click on F9-Start and measure the vibration level and phase angle in turn without test weight.
Duration of the measuring process may amounts 2-10 sec.

Run 1 - Test weight in plane 1
4. Stop the machine and mount a test weight of suitable size arbitrarily in plane 1.
5. Start up the machine, click on F9-Run and measure the new vibration level and phase angle. Duration of the measuring process may amounts 2-10 sec.
6. Stop the machine and remove the test weight

Run 2 - Test weight in plane 2
7. Mount a trial weight of suitable size in plane 2 .
8. Start the machine again, click on F9-Runand measure the vibration level and phase angle once more.
9. Stop the machine and remove the test weight

Step 4 - Calculation
10. The values of the correction weights and angles required will be calculated automatically and shown in popup form.

fig.6 Two plane balancing. Correction weight mounting
11. Mount the correction (balance) weights at the positions indicated in popup form at the same radius as the test (trial) weights (as shown in the figure in right column).
12. Start up the machine again and measure the amount of residual unbalance in the rotor , to see how successful the balancing job has been .

4. Other features
4.1 Vibrometer mode.
To select Vibrometer mode click "F5- Vibrometer" button in the main window for two-(one-) plane balancing
V1s (V2s) - summary vibration in plane 1(2) (mean-square) V1o (V2o) - vibration in plane 1(2) (first "revolution" harmonic value) In the right side you can see spectrum window.
4.2 Influence coefficients
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.
4.3 Archives and reports.
To save balancing information click"F9- Add" to archive in the balancing result pop-up window (see Tab.1). Input machine type ("Name") and other information in the table.
To print report click "F9-Report"
