LEICA DISTO FAQ

For which segments is the Leica DISTO A8 a great help in day to day business? The Leica
DISTO A8 is the perfect measuring help for several different target groups just to mention a few of
them it would be: Scaffolding, Forestry and Wood companies, cable companies, telecom, underground
construction, crane builders, carpenters, joiners, architects and many more.
ERROR MESSAGES
What does the displayed message E 255 mean? The return signal is too weak, measuring times are
too long. The measured distance must be more than 250mm. Use a target plate to reduce measuring
times.
What does the displayed message E 256 mean? The return signal is too strong. If using target
plates, the white side should be used for measuring short distances.
What does the displayed message E 272 and E 288 mean? Turn the instrument off and on again.
If the messages continue to be displayed, the instrument has to be sent in for servicing, as there is an
internal module error in the electronics. Please contact your dealer nearby.
MEASuRInG TECHnIQuES
What are favorable/unfavorable measuring conditions?
•
•
•
Materials with good reflecting characteristics, meaning they reflect the laser beam in a divergent
(not mirrored!) manner
Laser dot is brighter than the ambient light
Betrieb Operating within the allowable temperature range (-10° + 50° C)
unfavorable measuring conditions:
•
•
•
•
•
•
•
Highly reflective surfaces
Highly absorbing surfaces, such as wet or dark surfaces
Operating at the limits of the allowable temperature range
Not waiting for temperature calibration
Very intensive ambient light
Shimmering
For optical and safety reasons, do not measure against colorless liquids (water) or glass
FAQ Measurement of areas for polygonal rooms
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. At following
link you will get a template with formulas where you can even transfer the data for the distances into
the according cells.
