Check the accuracy of your Leica Lino laser levels regularly and particularly before important measuring tasks.
Checking the accuracy of the leveling
Set the instrument on a tripod half-way between two walls (A+B) that are approx. 5 m apart. Place the Lock switch 3 in the "Unlocked" position. Direct the instrument at wall A and switch on the instrument. Activate the horizontal laser line or laser dot and mark the position of the line or the dot on wall A (-> A1).
You can measure the area of a polygonal room by taking it apart into triangles and rectangles. You have to split the layout of a room in triangles and rectangles which cover the whole area once. After this you can add all areas together and will get the total area of rooms with even complex layouts.

"I was recently given the opportunity to test out the new Leica DISTO™ D810 Touch – a hand held laser distance measure complete with a touch screen and on-board digital camera. Although I have previous experience with the older Leica DISTO™ A5, it it was a good to get my hands on the new model."
