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 point and mark the position of the line or the point on wall A (-> A1).

Rotate the instrument by 180° and mark the hori- zontal laser line or the laser point 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 point 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.
