Detection : Select RMS, peak or P-P.
Resolution : Low, Normal, High, 0.03 Order, 0.015 Order, 0.008 Order, 0.004
Order. Note: If you choose higher resolution, it will take longer time to complete a
measurement. However, if there is other vibration signal which is very close to
the balancing speed, you’ll need to choose higher resolution so as to filter out the
interference. For example, to balance a pair of pulleys whose rotation speed is
very close to each other, you need to use higher resolution measurement to
separate the two rotation signals.
Average Times : Select 10, 20, 50 or 100 times.
Tolerance : Selecting Tolerance on the main
display will open up a Tolerance setup
window. This window allows you to enter the
desired ISO Grade for the balance job.
ISO 1940 Grade : Select from the pull-down
menu one of the following grades. When
you select [ Applied to Tolerance ] it will apply
the values as shown in the column below.
According to ISO 1940, the balance quality of
a rotor is graded from G0.4 (the best) to
G4000 (the worst) or user defined. The
balance grade is a calculation by the rotor’s
maximum operational speed and the rotor’s
eccentricity; where the eccentricity can be derived from the total rotor weight, the
radius for balancing and the residual imbalance mass. When user defined is
selected, you can only change the value for Tolerance for P1. The other fields
are not selectable when user defined is selected.
Balance grades available are:
G0.4 G100
G1 G250
G2.5 G630
G6.3 G1600
G16 G4000
G40 User Defined
