Evaluation
Evaluation of the data
The following data are listed in the data screen for each completed
balancing run:
-
M
ass
: Mass of the balancing weight
- a
ngle
: Fixing angle
- V
ibration
: Vibration overall values (RMS, 0-p, p-p*)
- a
ngle
: Phase angle
If you entered the rotor mass and the balancing radius in the machine
setup or the tools menu respectively, then the achieved balancing
quality and the centrifugal force on the rotor are also calculated. As
a reference RPM, either the measured RPM or the explicitly entered
RPM value is used (parameter, Speed (for balance quality), p. 2-22).
If the balancing quality is within the range of tolerance, the "smiley"
appears and indicates the end of the balancing procedure.
Data View
• Press the MENU button in the data screen and click on "Data". The
"Data View" screen appears.
Here you can combine several balancing weights to a single weight
and display the following information:
-
M
achine naMe
: Name of the machine setup if used
- D
ate
&
tiMe
: Date and time of the last balancing run
- s
peeD
: Current rotational speed
- b
alance quality
: Balance quality relative to reference speed.**
- r
esiDual unbalance
: Imbalance after the last balancing run
An icon marks the balancing runs in the list where the attached bal-
ancing weight was removed again from the rotor after the measure-
ment (e.g. trial run with weight in plane B: ('1BB'), see figure below).
The corresponding vector is represented by a dashed line in the polar
diagram (see illustration on page 2-10).
