Side display for balancing runs


1. Header
This field displays the name of the measuring run.
Depending on the measuring run, the name can be:
  • Initial run
  • Test run plane A
  • Test run plane B
  • Verification run 1
  • ...

Use measurement run for unbalance calculation

2. Use measurement run for unbalance calculation
Two inputs are needed for unbalance calculation:
  • How was the rotor mass changed?
  • What was the resulting vibration?
For the first unbalance calculation VM-BAL uses the data from the test runs. However, VM-BAL can also use verification runs in its calculations. This can be advantageous in the last balancing stage when a large portion of the initial unbalance has been compensated already. In such cases balancing would be based on vibration data measured under very different conditions. Instead of performing new test runs VM-BAL may simply include verification run results in its calculation. This option can be selected in the settings. Even if you have enabled the inclusion of verification runs you can still disable this option individually for each run.

3. Edit button
Changing the calculation is not possible in most situations of the balancing procedure, i.e. the edit button is deactivated.
