EASURING ABSOLUTE
Zero point is to be set by reversal measurement. Now the BlueLEVEL BASIC will read deviations from the absolute
horizontal position.
Using BlueLEVEL BASIC with a BlueMETER BASIC the value of the display is shown in [Arcsec] or in [µm/m].

EASUREMENT
It is not always required to set the instrument to zero by a reversal measurement
(absolute ZERO). If e.g. the straightness of a line is measured most of the time the
relative straightness is only required.
The same applies when lines, parallels, flatness is measured with the WYLER LEVEL
SOFT PRO. These are relative measurements.
Using the machine tool software MT-SOFT an absolute measurement is important
because different elements of a machine tool must be compared even at a later stage of
the measurement. E.g. the horizontal guide way must be compared to the vertical axis
of the spindle. Only when the measurement is done in absolute mode such a
comparison is possible.

IFFERENTIAL RESPECTIVELY REFERENCE MEASUREMENT USING AN ENGINEER SET
Such a differential measurement, mostly done with an engineer set (two BlueLEVEL BASIC and one BlueMETER
BASIC), is useful or necessary in some of the following cases:
•
Measurement on an object with vibrations imposed
•
The inclination of the object to be measured will change by the weight of the instrument
•
The floor is unstable (heavy loads in the close surroundings)
•
The relative pitch and roll on a machine must be measured.
The Engineer set usually consists of:
Two BlueLEVEL BASIC and one BlueMETER
BASIC;
Data transmission via cables

Connecting the instruments performing a differential measurement
•
One of the instruments is used as measuring instrument and the other as reference instrument.
•
The measuring instrument is connected to port "A" the reference instrument to port "B".
•
Both instruments must be placed looking the same direction.
