Initial run/Test run A
The 2-plane balancing procedures for
the Initial run and Test run A
correspond in their operational steps.
See section 7.7.
Switch to the display of the
correction and prog-nosis
for plane B with »1/2«.
7.
Calculate the correct-
ion and prognosis
The VIBROTEST 60 calculates:
•
The correction for plane A
allowing for test weights that
remain on the rotor.
•
The prognosis of residual
unbalance forboth planes. The
prognosis value for both planes is
identical.
The following are displayed in the
main menu:
•
Effect of the test weight A (TRA)
on plane A.
•
Calculated correction (CMA) for
plane A.
•
Prognosis of residual unba-lance
(PV) in plane A
With the function button »1/2« the
values for plane B are displayed.
The Test run A can be repeated with
»SELECT«.
The user can now choose between
two options in the balancing
procedure:
•
Carry out Test run B
•
Do a Check run
Assess whether the
prognosis of the resi-
dual vibration is low
enough. In case of a
prognosed value that is
not low enough Test
run B should be carried
out.
Attach the correction
weight at plane A on
the rotor
(e.g. 97,7 g at 23°).
No correction weights
are attached in plane
B.
