1-plane balancing
ATTENTION
Measure 'Initial' run
Enter mass and angle for trial run
Measuring the initial imbalance
1. Switch the machine on. Wait until the machine has reached the
balancing RPM and operating temperature if necessary.
2. Press 'Enter' to start the measurement.
First, VIBXPERT records the RPM. The green LED flashes with each
trigger pulse. If the RPM varies too much, a warning message appears.
Finally, the instrument measures the amplitude and phase of the RPM
synchronous vibration. If the values are unstable, the average is auto-
matically increased.
3. If the measurement values are stable, press 'Enter' to stop the mea-
surement (see previous page).
To repeat the measurement, press 'Enter' again.
4. Switch the machine off.
Trial run
1. Press the right navigation key to open the data screen for the trial
run.
2. Enter the mass and fixing angle for the trial weight.
Click on the mass or angle field under the rotor graphic, and enter
the respective value in the number editor.
If the trial mass is applied at random, there is a risk of increased
imbalance and thus an increased vibration load. Especially if
vibration loads are already very high, this may result in further
machine damage.
3. Press the right navigation key until the next screen appears.
