Checking the accuracy of the Leica
Lino
)
Check the accuracy of your Leica Lino regu-
larly and particularly before important measuring
tasks.
Checking the accuracy of the levelling
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).
Rotate the instrument by 180° and mark the hori-
zontal laser line or the laser dot in exactly the same
way on wall B (-> B1).
Then place the instrument at the same elevation as
close as possible to wall A and again mark the hori-
zontal laser line or the laser dot on wall A (-> A2) .
Rotate the instrument by 180° again and mark the
laser on wall B (-> B2). Measure the distances of the
marked points A1-A2 and B1-B2. Calculate the differ-
ence of the two measurements. If the difference
does not exceed 2 mm, then the Leica Lino is within
tolerance.
