Vibration Measurement Instruments
Speed tolerance
The tolerance of the current balancing speed is compared with the saved balancing speed to consider wheth-
er the measurement is suitable for the balancing procedure. When the measured speed is outside of this tol-
erance, the speed value will be shown in yellow. It is important to measure the vibrations at the same RPM
during the whole balancing session.
No of maximum averages
This is the maximum number of measurements that can be used to save the data if the Auto save measure-
ment is enabled. If the measurements are not stable enough (the speed is out of tolerance), the instrument
will save the data when this number of measurements is reached.
Rotor settings
In this menu you enter:
• Balancing Radius R1
• Rotor mass (Kg)
• ISO 1940-1 Balance quality
If Enabled, you will enter the settings for ISO Quality before the measurement starts. Here you select the
balancing quality grade. Enter the maximum rotor speed, weight and dimensions. The instrument then cal-
culates maximum allowable residual unbalance and compares this value with the remaining unbalance in the
rotor.
• Operating speed (RPM)
The operating speed is the maximum speed that the rotor will ever reach in normal operation, not the balanc-
ing speed you have currently selected.
