TESA NIVELTRONIC

3.3 Electrical zero setting of the pointer

Provided the measuring instrument is swit-
ched on and placed on an horizontal surface,
the pointer can be set to zero by means of the
potentiometer.
This setting is sufficient to allow any deviation
in inclination to be detected and further read as
the difference between the values obtained from
two successive measurements, which are exe-
cuted without shifting the instrument.

4 MEASUREMENT

– To get reliable measurement results, carefully
clean the measuring faces of your level as
well as that of the part to be measured.
– Always place your instrument with care at the
measuring location.
– Handle the level vertically, especially when
measuring cylindrical shafts. The correct
position can easily be checked by looking at
the transversal vial. If the level is not held ver-
tically, deviations will arise which are called
"Twist errors".
– Depending on the measuring uncertainty you
wish to achieve, a special attention should be

However, this way to set your level to zero does
not mean it is adjusted to zero. For this purpose,
you must perform all settings described under
both chapters 3.1 and 3.2.
paid to the temperature between the electro-
nic level and the part to be inspected. If ne-
cessary, wait until temperature has stabilised.
– Before the measurement outset, make sure
you have made all display settings according
to chapter 3.
– After completion of your measuring work,
store your level as explained in chapter 5.
