    1.3.2 Absolute measurement / Relative measurement / Differential measurement Absolute measurement (Absolute ZERO) Condition for the absolute measurement is the performing of a reversal measurement for determining the absolute zero (to the centre of the earth) After this procedure the instrument will display the effective deviation from the centre of gravity.

  • Page 10: General Remarks About "Angles

    1.3.3 General remarks about "ANGLES" Every angle may be defined in different ways. The most popular way is a definition in Degrees / Minutes / Seconds. This is shown in the graph. Such a definition is especially useful for larger angles. With an angular measuring instrument not only an angle may be measured but also the height of a certain point over a defined base length can be...

  • Page 12: Zero Setting By Reversal Measurement (Absolute Zero)

    It is not always required to set the instrument to zero by reversal measurement (absolute ZERO). If e.g. the straightness of a line is measured only the relative most of the time the relative straightness is only required. The same applies when lines, parallels, flatness is measured with the WYLER LEVELSOFT. These are relative measurements.

  • Page 13: Differential Respectively Reference Measurement Using An Engineer Set

    Picture: Two LEVELTRONIC „NT“ and a LEVELMETER 2000 connected to laptop equipped with the WYLER software LEVELSOFT Remarks concerning NT instruments: It makes sense to combine a LEVELTRONIC NT and a MINILEVEL NT to an engineer set. With such a combination a great variety of other measuring tasks requiring a stand-alone instrument may be fulfilled.

For precise square measurements an angular model fitted with magnets in the vertical face should be used. (Elimination of deformation due to manual pressure).

  • Page 15: Angular Measurements

    After the reversal measurement precision measurement with measuring uncertainty of 3 to 5 µm/m is possible. The determination of the instrument's angular error is done as follows: In the WYLER LEVELSOFT 99 a new set-up allows the easy measurement of squareness of rectangular objects.
