After marking the grid the inclination measuring instrument must be placed on the object to be measured as shown below. For the flatness measurement first the longitudinal lines are measured and then the transversal lines. For reasons of measuring accuracy it is recommended to work with a measuring and a reference unit (differential or reference measurement) For reference measurement (differential measurements) with two instruments it is important, that

Ideally
the flatness measurement is executed with a set of instruments of 2 BlueLEVEL
or 2 BlueLEVEL
BASIC, connected through a
BlueMETER
to a PC or Laptop.
The use of two instruments is (differential measurement) recommended in order to eliminate external influences and sources of error, such as vibrations, instability of the measuring object, etc. |
