Introduction
With the acquisition of this Leica digital level you
have chosen a product of excellence, with state of
the art ergonomy and outstanding measuring accu-
racy. Both types of the instrument feature electronic
reading of the measuring staff height. The bull's eye
bubble only has to be roughly set for every sta-
tioning. The fine adjustment of the target beam is
done automatically by the high-precision compen-
sator. A key press triggers the electronic measure-
ment. Should it not be possoble for once, to make
an electronic measurement, then the height can be
optically read from a conventional, metered staff
and manually enterred with the keypad.
Leica digital levels come with a wide range of soft-
ware functions. Single height measurements are
easy to make and also just as easy is measuring all
the elements in a line levelling job. With the pro-
gram "Line Adjustment", measured heights can be
compared directly with the height of fixed points and
adjusted to them if desired. Staking out absolute
heights or height differences or point-to-point mea-
surements are all easily possible.
The unique concept of format files enables the out-
put of store data in almost any format. The format
files can be created individually and modified asy
desired. The logfile e.g., can be completed in the
field and transferred to an internal memory card.

Principal of measurement
The bar code of the staff is stored in the instrument
as a reference signal. When measuring, the visible
section of the staff within the field of view is captu-
red by the line decoder as a measuring signal. Then
the measuring signal is compared to the reference
signal. This results in the height reading and hori-
zontal distance. The staff must be perpendicular
during measurement, as for optical levelling. With
artificial lighting of the staff, mesurements can be
made in the dark (The sensitivity of the sensor ran-
ges from the highest frequiencies of visible light
down to the frequency of infra red light).
Validity
This manual is valid for both instruments of the DNA
series. Sections only valid for the DNA03 are mar-
ked accordingly.

Vertical axis tilt
DNA03_05
After centering the circular level the instrument is
almost horizonal. A minimal instrument tilt remains,
this is the vertical axis tilt.
Compensator
DNA03_06
The compensator corrects for the vertical axis tilt on
the line-of-sight so that the instruments aim is exa-
ctly horizontal.

The Collimation error (α) is the vertical angle bet-

Applications
DNA10
Mainly for technical levelling tasks.
DNA03
Technical levelling and precision levelling.
Staff selection
Measuring accuracy depends on the staff used in
combination with the instrument. Use standard
staffs for low to medium range accuracy and invar
levelling staffs for the highest precision.
Range of application
• Simple measurements using staff and distance
readings
• Line levelling
• Sureying and set out intermediate points.
• Online operations with a computer.
Line levelling
Dependent on the required accuracy the same rules
for levellling and regulations within the given coun-
tries apply as for optical levelling.
Adhere to the following general rules:
• Maintain same target distance for back and
foresight.
• Measure a fore and back run and check it by
the error after the closing point.
Exclusively for precision levelling:
• Limit target distance, < 30m.
• Minimum ground clearance of >0.5m required
to minimize refractionary influences of ground
proximity.
• Double observance (BFFB, aBFFB) to increase
the reliability of the measurement and to reduce
possible errors caused by the staff sinking.
• Applying alternating observations procedures
(aBFFB = BFFB FBBF) to eliminate horizontal
tilt (residual error of the automatic
compensator).
• Use an umbrella in strong sunlight.

16
• Precision Mode: "Precise" is activated in the
tolerance-settings for line levelling, the
instrument monitors the distance of the height
reading (Ziellinie) to both ends of staff, top and
bottom. The reduced 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
precision 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 possible hut not necessary.

17
Area levelling
Unlike line levelling, the individual target distances
in area levelling may be very different. Depending
on the required accuracy, a possible line-of-sight
error or the influence of the earth’s curvature may
have be taken into consideration.
In strong sunlight and when working for
long periods, cover instrument and stand
with an umbrella.

18
Computer software package
Leica Geo Office (LGO)
The Leica Geo Office (LGO) software package
includes a number of programs and tools that sup-
port working with the instrument. LGO-Tools is a
part of the complete LGO package and can be
installed from the supplied CD.
After the tools have been successfully installed, the
following program modules are available:
• Data Exchange Manager
Data exchange of fixed points, measurements,
code lists and data output formats between the
instrument (internal memory) and the computer.
Data exchange between PCMCIA-card (in the
instrument) and the computer.
• Coordinate Editor
Import/ export/ create/ edit coordinate data.
• Codelist Manager
Creates and edits code lists.
• Software Upload
Uploads system software and measuring
programs.
• Format Manager
Creates and edits user defined output formats.
• Configuration Manager
Creates and edits user defined instrument
settings.
• DNA GSI Converter
Converts DNA03/ DNA10-data in the new GSI-
format into data in the old GSI-format of the
NA3003/ NA2002.
For more information on the Leica Geo
Office refer to the detailed Online-help.
LEICA Geo Office (LGO) is available as a separate
software package and includes the basic module as
well as the LGO Tools package. The base module
and the corresponding options offered supportvi-
sualization, calculation, quality testing and recor-
ding of measurement data of various Leica
instruments.

19
The following options are available for the evalua-
tion of levelling data:
• Display, editing and evaluation of single line
levelling
• Creating and adjusting1D height grids.
Further information on the LGO will gladly be given
by your local Leica representative.
Data flow:
We recommend using the XML-format to transfer
measurement data from the DNA to the LGO and its
modules. The required Format file (DnaXml.frt) is
located on the supplied CD and can be installed on
the instrument with the "Data Exchange Manager".
The transfer of job data from the instrument
to the computer is then also done through
the "Data Exchange Manager".
As LGO / LevelPak-Pro read in *.lev files by default,
we recommend giving the file to be transferred to
the computer a *.lev name. The following input
mask is displayed in the LGO Data Exchange
Manager when transferring data to the computer. As
an example, the format file DNAXml5 was selected.
We advise against transferring measured data in
GSI format from the level to the LGO software pak-
kage. As the GSI format does not include all infor-
mation, errors may occur during height calculations
and lead to wrong results.
Transferring measurement data from the level test
from the DNA to LGO is also not recommrnded in
XML format.

20
PCMCIA or CF card
Measured data is stored in the internal memory of
the DNA03/ DNA10 and remains there. In addition,
data can be backed up to a PCMCIA or CF card
from the internal memory.
The system supports the PCMCIA standard for
ATA-Flash, SRAM or CF memory cards. Data
exchange with the computer is done via an internal
PCMCIA- drive or with the external OMNI-drive offe-
red by Leica Geosystems.
Files can also be exchanged between the memory
card in the instrument and the computer via the RS
232 serial interface using the Leica Survey Office
software.
Due to possible incompatibility with internal
drives, data exchange with SRAM-cards is
best done with the external OMNI-drive.
