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
B1
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
