Standing axis inclination
Angle between plumb line and
standing axis. Standing axis tilt is
not an instrument error and is not
eliminated by measuring in both
faces. Any possible influence it may
have on the Hz-direction resp. Vangle is elliminated by the dual axis
compensator.
Line-of-sight error (Hz-collimation)
The line-of-sight error is the deviation from the perpendicular
between tilting axis and line-ofsight. This could be eleminated by
measuring in both faces.
V-Index (Vertical index error)
With horizontal line-of-sight the Vcircle reading should be exactly
90°(100gon). The deviation from
this values is termed V-index (i).
Plumb line / Compensator
Direction of gravity. The compensator defines the plumb line within
the instrument.
TPS800_Z07
Zenith
Point on the plumb line above the
observer.
TPS800_Z08
Reticle

Introduction
Area of applicability
This User Manual is valid for all instruments of the
TPS800 Series.
TC Instruments are equipped with an invisible
infrared EDM and TCR Instruments with a visible
red laser for reflectorless measuring.
Sections only valid for TCR instruments are marked
accordingly.
PC Program Package Leica Geo Office Tools (LGO-Tools)
The program package LGO-Tools is used for the
data exchange between the Total Station and the
PC. It contains several auxiliary programs in order to
support your use of the Instrument.
Installation on the PC
The installation program can be found on the CDROM supplied. Please note that LGO-Tools can
only be installed on computers with MS Windows
98, 2000 or XP operating systems.
Any previous versions of LGO-Tools on
)
your computer must be uninstalled first before
installing the new version.
For the installation call program "setup.exe" in the
directory \LGO-Tools on the CD-ROM and follow
the input instructions of the installation program.
Program content
After successful installation the following programs
appear:

Introduction
Power Supply
Use the Leica Geosystems batteries, chargers and
accessories or accessories recommended by Leica
Geosystems to ensure the correct functionality of
the instrument.
Power for the instrument can be supplied either
internally or externally. An external battery is
connected to the instrument using a LEMO cable.
• Internal battery:
One GEB111 or 121 battery fit in the battery
compartment.
• External battery:
One GEB171 battery connected via cable.

3 Single cells in the battery adapter GAD39
Your Leica Geosystems instrument is powered by
rechargeable plug-in batteries. For this product, we
recommend the basic battery (GEB111) or the Pro
battery (GEB121). Optionally six single cells can be
used with the GAD39 battery adapter.
Six single cell batteries (1.5 V each) supply 9 Volts.
The voltmeter on the instrument is designed for a
voltage of 6 Volts (GEB111/ GEB121).
The battery charge is not displayed correctly
)
when using single cells. Use the single cells with the
battery adapter as emergency power supply. The
advantage of the single cells is in a lower rate of
discharge even over long periods.

Leica TPS800-2.0.0en
Distance measurement
A laser distancer (EDM) is incorporated into the
instruments of the TPS800 series.
In all versions, the distance can be determined by
using an invisible infrared beam which emerges
coaxially from the telescope objective.
Measurements to strongly reflecting
)
targets such as to traffic lights in infrared mode
without prism should be avoided. The measured
distances may be wrong or inaccurate.
For applications without reflector, the TCR-version
also use a visible red laser beam which emerges
in the same manner. A special arrangement of the
EDM, and appropriate arrangement of the beam
paths, enable ranges of over five kilometres to be
attained with standard prisms.
Miniprisms, 360° reflectors and reflector tapes can
also be used, and measurement is also possible
without a reflector.
When a distance measurement is trig-
)
gered, the EDM measures to the object which is
in the beam path at that moment.
If e.g. people, cars, animals, swaying branches, etc.
cross the laser beam while a measurement is being
taken, a fraction of the laser beam is reflected and
may lead to incorrect distance values.
Avoid interrupting the measuring beam while taking
reflectorless measurements or measurements using
reflective foils. Measurements to prism reflectors are
only critical if an object crosses the measuring beam
at a distance of 0 to 30m and the distance to be
measured is more than 300m.
In practice, because the measuring time is very
short, the user can always find a way of avoiding
these critical situations.

Be sure that the laser beam is not reflected

by anything close to the line of sight (e.g. highly
reflective objects).
When a distance measurement is triggered,
)
the EDM measures to the object which is in the
beam path at that moment. In case of temporary
obstruction (e.g. a passing vehicle, heavy rain, fog
or snow) the EDM may measure to the obstruction.
When measuring longer distances, any
)
divergence of the red laser beam from the line of
sight might lead to less accurate measurements.
This is because the laser beam might not be
reflected from the point at which the crosshairs are
pointing.
Therefore, it is recommended to verify that the Rlaser is well collimated with the telescope line of
sight (refer to the chapter "Checking and adjusting").
Do not measure with two instruments to the
)
same target simultaneously.

Red laser to prisms
Accurate measurements to prisms should

be made with the standard program (Infrared mode).
Red laser to reflector tape
The visible red laser beam can be used to measure
to reflective foils, also. To guarantee the accuracy
the red laser beam must be perpendicular to the
reflector tape and it must be well adjusted (refer to
the chapter "Checking and adjusting").
Make sure the additive constant belongs to

Primary use/charging
)
• The batteries must be charged prior to using for
the first time because it is delivered with an
energy content as low as possible.
• For new batteries or batteries that have been
stored for a long time (> three months), it is
effectual to make 2 - 5 charge/discharge cycles.
• The permissible temperature range for charging
is between 0°C to +35°C / +32°F to +95°F. For
optimal charging we recommend a low ambient
temperature of +10°C to +20°C / +50°F to
+68°F.
Operation/Discharging
)
The batteries can be operated from -20°C to
+55°C/-4°F to +131°F.
Low operating temperatures reduce the capacity
that can be drawn; very high operating temperatures
reduce the service life of the battery.

Instrument Setup
Description
This topic describes an instrument setup over a
marked ground point using the laser plummet. It is
always possible to set up the instrument without the
need for a marked ground point.
Important features:
)
• It is always recommended to shield the
instrument from direct sunlight and avoid
uneven temperatures around the instrument.
• The laser plummet described in this topic is
built into the vertical axis of the instrument.
It projects a red spot onto the ground,
making it appreciably easier to centre the
instrument.
• The laser plummet cannot be used in
conjunction with a tribrach equipped with an
optical plummet.
