TR-02A Tripod
10.9.1 Introduction
TR-02A is an Optional Accessory of the LR-01 Programmable Optical
Repeater. It allows LR-01 to be easily supported during field
measurements.
Each of these instruments has a securing screw, usually placed on the
bottom part of its container, that enables it to be easily and quickly put into
place through the 8053-SN swivel supplied with the tripod.
The design and materials of the TR-02A tripod have been specially
selected to prevent it from disturbing the sensors and, therefore, the
measurements taken.
The height of the tripod can be adjusted by means of its extendable legs
and it is furnished with special feet that are able adapt to all surfaces
thereby improving stability. The height of its central support can also be
adjusted.
It is supplied with a small protective carrybag to make it easy to carry.
