Leica Geosystems Viva TPS October 2010 TS11 15 Total Stations Check and Adjust Procedure Summary Leica builds total stations to the highest quality and calibrates each instrument before it leaves the Factory After the instrument is shipped or used in the field under changing temperature conditions the instrument will physically change In order to provide the customer with the ability to field calibrate every total station Leica offers the Check and Adjust routine on the TS11 15 instruments This guide will explain why the Check and Adjust is needed and how to perform the procedure This procedure will allow the user to assure that the instrument is providing measurements to standards eica Geosystems 2010 Leica Geosystems Inc All rights reserved when it has to be right TS11 15 Check and Adjust Why is procedure needed Why is the procedure needed When should you perform procedure What adjustments are determined by procedure TS11 15 Total Stations FW Ver 3 00 Check and Adjust Procedure Leica instruments are manufactured assembled and adjusted to the best possible quality Quick temperature changes shock or stress can cause deviations and influence the instrument accuracy The physical relationship of the axis of the instrument are physically different if the operating temperature of the instrument is 32 F 0 C versus 95 F 35 C Materials contract and expand Survey instr2.
