The R-7.1 is a hard-bearing machine and permanently calibrated. Therefore with a new rotor type just the positions of the balancing planes and the correction radii have to be setup at the unbalance measuring system. Then the balancing process starts. Time consuming calibration runs are not neccessary, which for very small rotors cause problems with manipulation of extremely small unbalance test weights. The core of the R-7.1 is a rigid measuring table, which is designed to the Hofmann force measuring principle. The integrated force sensors measure the force generated by the rotor unbalance directly within the force flow and with very high sensitivity. Those sensors do not depend on temperature fluctuations or external electro-magnetic fields. As a result unbalances can be measured already at quite low speeds. The unbalance measuring system provides a digital processing of the measuring values with a precise separation of the unbalance vibration. Its Windows operating system offers intuitive, simple and reliable operation. The unbalance correction is being displayed in terms of mass-, unbalance- or correction
