Balancer mode 7 - 3
1. New program – BALANCING SETUP
The creation of a new program entails setting of a series of parameters. This is done in the
BALANCING SETUP screen.
1. Number of planes
This is the number of planes on which to act to correct the unbalance of the
rotor. The number can be 1 or 2.
2. Filter accuracy
Balancing under not particularly stable signal conditions is certainly critical and
needs acquisition for longer times in order to obtain a satisfactory quality of the
value measured. This can be achieved by acting on the filter accuracy:
acquisition made with a broad filter: faster, but only suitable for
particularly stable signal conditions (high unbalance values).
acquisition made with a narrow filter: suitable in most conditions.
acquisition made with a very narrow filter: suitable for
particularly critical signal conditions (low unbalance values);
requires longer times
N.B.:
Depending on the accuracy selected for the filter, the instrument automatically
determines the number of revs. necessary for each acquisition. As it could be
necessary to have up to some hundred revs. in certain situations, the time required
for each measurement could likewise be equal to some tens of a second. Taking
into account that a certain number of consecutive acquisitions is necessary so that
the quality of the measurement can reach acceptable levels, the time required for an
acquisition could also entail several minutes in the case of slow rotors.
