Option Description
F3 Enter Known
Weight
Enter the desired weight between 0.00 and 10,000, typically the
calculated correction weight, or import it from the Balance Correction
screen. The default is 0. You cannot import discrete positions. This field is
unitless. If you access Adjust Radius from the Trim Run Applied Weight
screen, the units are as defined for the job.
F4 Enter Known
Radius
Enter the desired radius between 0.00 and 650.00 inches or 0.00 and 1651
cm, or import it from the Balance Correction screen. The default is 0. You
cannot import discrete positions.
F9 Enter
Available Weight
Enter an available weight between 0.00 and 10,000. This field is unitless. If
you access Adjust Radius from theTrim Run Applied Weight screen, the units
are as defined for the job. An entry is not required if you enter an available
radius. The default is Unknown.
F10 Enter
Available Radius
Enter an available radius between 0.00 and 650.00 inches or 0.00 and
1651 cm. An entry is not required if you enter an available weight. The
default is Unknown.
3. Press F1 Calculate Solution or Enter.
The Circumference Conv. Solution screen displays the solution as a continuous
weight position. The Enter key is inactive on this screen.

Press F7 Adjust Radius Calc. to exit and return to the calculation screen.
9.15.8 Amplification Factor
The Amplification Factor option lets you enter the physical data that describes the rotor. The
program then calculates the vibration’s amplification by the proximity of a resonance and
the system lag, using selected reference and trial run data.
Equipment with amplification factors exceeding six may be difficult to balance. The most
common cause is a resonance close to rotational frequency. System lag reflects the
difference between the measured vibratory high spot and the true rotor heavy spot.
Amplification Factor is available only after you acquire reference run and trial run data.
Note
This is available only in Advanced Balance mode.
Procedure
1.
From the Balance main menu, press ALT > F6 Calculator Mode > F10 Amp. Factor.
2. Set the following options as necessary.
Option Description
F2 Select Meas.
Plane
Select the measurement plane to use. You may want to select the
