Light tripod easy going for
field calculators / notebooks
The ideal use of a field calculator not integrated in the total station/EDM was the rotatable holder directly
on the instrument tripod (our system 168, see catalogue page 44).
Large amounts of data, which have to be available in the field today, as well as the desire to do the
complete data processing already in the field, have made it necessary to use a notebook with a strong
processor, high memory capacity and a large display. This is not possible directly on the instrument tri-
pod because of its high weight. Our investigations during use have shown, that more measuring errors
are produced with a weight of more than 1 kg. In addition, the holder together with the necessary coun-
ter weight is heavy and uncomfortable to use.
Another reason to separate the notebook from the instrument tripod is the modern way of measuring –
in the one-man-operation or with the robotic measuring the total station/EDM will be operated from a
control unit or with the notebook. The data transmission by cable will then be replaced by a Bluetooth or
radio connection without cable. The solution with radio covers also large distances (1 km).
However, when using a notebook (laptop, tablet-PC), which will be hold with a carrier system around the
neck, the relatively high weight of the machine is uncomfortable during longer use.
The use of the calculator on a light tripod does also resolve this problem. Together with a data transmis-
sion without cable, the notebook can be placed anywhere near the total station/EDM. When measuring in
the robotic mode, the simple taking and placing of the calculator directly at the object point is possible.
There is no disturbing heavy tools around the neck; the operator can do something else during measu-
ring.
The new calculator tripod easy going was developed especially for this area of application. It is characte-
rized by the following details of construction:
•very simple use and extremely robust
•very light (weight: 850 g)
legs and middle strut made of very durable compound material: blend of carbon/fibre glass
comfortable carrying of the tripod also during cold weather
secure clamping of the middle strut with a high quality synthetic clamp and an eccentric clamp lever
•red coloured for better visibility in the traffic, on the construction sites etc.
dimensions: 0,75 m (retracted) till 1,2 m (extended)
•many connections for different calculator holders
alternatively available with changeable pins of stainless steel or elastic balls
