Rotor weight 
(as long as an accommodation of the rotor is possible due to the geometric data and the minimum achievable residual unbalance is sufficient for the balancing task.)

Belt Driving Diameter
10-150 mm
Balancing speeds based upon 50 mm belt driving diameter approx.
(with other belt driving diameters, the speeds change accordingly. in addition, the speed range of the measuring unit must be taken into account. see item 2) 
220 - 2 200  rpm

umar minimum achievable residual unbalance (*according to iso2953)
each bearing plane 0.1 gmm per kg rotor weight
but not better than the maximum measuring sensitivity of the measuring unit 0.1gmm
(* this value is refering to the measuring speed of 1000 rpm with cab708, also influenced by the rotor characteristics and support bearing. see specification of the measuring unit)

2.        Presentation of Unbalance or Unbalance Correction

->    Display in large, easy-to-read digits and in vector form, simultaneously for
        both correction planes, with amount and angular position.

->     The following types of unbalance display are available:
           - Dynamic unbalance in two correction planes
           - Static unbalance in any correction plane
           - Static and couple unbalance
           - Static and dynamic unbalance

->     The following methods are available for presentation of the type of
         unbalance correction:
           - polar: amount and angular position
           - components: amount at two adjacent locations
               (max. 100 symmetrically or unsymmetrical distributed locations).

3.        Setting the measuring instrumentation 

->        During instrument set-up, a clearly understandable presentation of the
           rotor mounting arrangement assists and guides the user through the
           procedure of entering the correct geometrical data for the rotor.

->        For storage and fast recall the set up parameters for frequently recurring
           types can be stored on the pc: the numbers of storable rotors practically
           are unlimited.

->        Basic Functions
           - Selection of six different accommodation possibilities.
           - Input of distances between correction planes a, b and c.
           - Input of correction radii.
           - Change-over between addition or removal of material in a given correction plane.
           - Presentation of different types of unbalance
(dynamic, static, stat./couple, or dynamic/static).
           - selection of type of correction display (polar or in components, sectors)
           - input or measurement of balancing speed
           - input of the desired tolerance per correction or control plane, or calculation
             according to din iso 1940

->        Additional functions
           - index balancing
           - single compensation
           - compensation of parallel key
           - input of an alphanumerical identification for each rotor
           - input of set-up data
           - re-calling previous unbalance
           - operator name
           - deviation of first unbalance correction location from zero angle

4.        Measurement 

->     Automatic adaptation of sensitivity to signal magnitude

->     Automatic start of measurement after required speed range has been reached

->     Manual or automatic locking of unbalance readout with pre-selection
         of measurement time, calculation of mean value.

->     Display of the tolerance in the vector display.

->     Comparison of measured unbalance with a specified tolerance and
         indication of a factor showing the relationship to the specified tolerance
        (x times tolerance); colour change and appropriate message on achieving
         the tolerance.

->      Display of unbalance or unbalance correction at the user's discretion.

->     Selection of units: metric, inch or mixed.

->     Automatic or fixed scale, with possibility of manual alteration.

5.        Reporting 

->     Extensive functions for adapting the measurement report to the
        user's requirements.

->     Capability of recording the current -
           - rotor data,
           - list of all rotor type data,
           - measurement data (balancing report),
           - calibration data.

->    Configuration of balancing report and storage for fast retrieval.

->     Predefined standard configuration.

->     Viewing of all entries and measurement results in a page preview.

->     User-specific header is possible (e.g. company address or corporate logo).

->     User-defined comments.

->     Storage of balancing report in a file for subsequent printout.

->     Supports all common printer types.

6.        Special features 

->     Manual display for angular indexing(option item)

->     Storage of measured unbalance values in a standard format for further processing

->     Simple use of programs available in the system (pocket calculator, note pad).

->     A password system can be used to protect the data from modification by unauthorized persons.

->     The software includes a variety of functions for automatic self-testing of the measuring instrumentation.

->     Communicating with measuring unit through can-bus, receiving the control signals  from the measuring unit, realizing the functions such as:
auto-stop after measuring,
over-speed monitoring,
clockwise and anticlockwise turning (not apply to servo motor).
