Set tolerances
Set tolerances must be adhered to during line level-
ling, depending on the application. Tolerance
checks are activated and deactivated here. With
tolerance check activated a message is displayed
as soon as the set tolerance is exceeded. This per-
mits corrective measures to be taken immediately.

Precision Mode: "Precise" is activated in the tole-
rance-settings for line levelling, the instrument
monitors the distance of the height reading (collima-
tion) to both ends of staff, top and bottom. The redu-
ced number of staff code elements may slightly
lower the measuring accuracy of measurements
taken on the edge of the staff. If the distance is less
than 50cm a warning is displayed. When this mode
is activated, the top and bottom limits of the staff are
automatically converted to a 3m Invar staff. In order
to use different staff sizes, the limit values can be
manuallly adjusted.
The precisioin mode also monitors measuring
distances critical to the staff. These distances
depend on the physical properties of the instrument
and of the staff. The measuring accuracy of height
measurements within these distance ranges may
also be slightly lower. A warning is displayed if the
measuring distance is within the following ranges:
13.250m - 13.500m and 26.650m - 26.900m.
The Precision Mode is meant as a helpful tool to
increase measuring accuracy. Activating Precision
Mode for line levelling with typical accuracy is possi-
ble nut not necessary.
