Check the accuracy of your instrument reg-
ularly and particularly before important
measuring tasks. Check
before checking the accuracy.
Levelling
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 in the "Unlocked" position (see
). Direct the instrument at wall A
and switch on the instrument. Activate the hori-
zontal laser line or laser point and mark the pos-
ition of the line or the point on wall (A1). Rotate
the instrument by 180° and mark the horizontal
laser line or the laser point in exactly the same
way on wall (B1).
Then place the instrument at the same elevation
as close as possible to wall A and again mark the
horizontal 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 dis-
tances of the marked points A1-A2 and B1-B2.
Calculate the difference of the two meas-
urements.
|(A1 - A2) - (B1 - B2)| <=2 mm
If the difference does not exceed 2 mm, then the
instrument is within tolerance.
Should your instrument be outside of the
specified tolerance, please contact a local
dealer or an authorised Leica Geosystems
distributor.
