CHAPTER 6 Instrument Technology 6 In this chapter: Angle Measuring Technology Distance Measuring Technology Tracklight StepDrive Motor System and Focus System LockNGo Tracking Technology Power Management Power Supply External Communication FOCUS 35 TOTAL STATION USER GUIDE 83
6 – Instrument Technology Angle Measuring Technology The principles of angle measurement are based on reading an integrated signal over two opposite areas of the graduated circle and producing a mean angular value. This eliminates inaccuracies caused by eccentricity and graduation. In addition, the angle measurement system compensates for the following automatic corrections: • Instrument mislevelment (deviation of the plumb axis). • Horizontal and vertical collimation error.
6 – Instrument Technology Correction for Collimation Errors HA/VA Collimation The horizontal collimation error is the deviation of the sighting axis from its required position at right angles to trunnion axis. The vertical collimation error is the difference between the vertical circle zero and the plumb axis of the instrument. Traditionally, collimation errors were eliminated by observing angles in both instrument faces.
6 – Instrument Technology Correction for Trunnion Axis The trunnion axis tilt error is the deviation of the trunnion axis of the telescope from its required position at right angles to the plumb axis of the instrument. Trunnion axis tilt error In the Spectra Precision FOCUS 35 Total Station, perform a pre-measurement trunnion axis tilt test to determine the trunnion axis tilt error.
6 – Instrument Technology Averaging Measurements to Reduce Sighting Errors The Spectra Precision FOCUS 35 Total Station automatically reduces sighting errors caused by the misalignment of the instrument to the target or by pole movement during measurement. The following techniques can be used: • Use LockNGo Tracker. When LockNGo Tracker is enabled, the instrument automatically locks onto and tracks the target. Manual sighting errors are reduced.
6 – Instrument Technology Beam Divergence All distance meter measurement beams diverge as the range from the instrument increases. The divergence of the distance meter beam relates to an increase in the size of the area being sampled, not to a degradation of the measurement precision. A larger measuring area at longer range is generally better because it enables smaller objects, such as power lines and antennas, to be detected and accurately measured.
6 – Instrument Technology Measuring to an inner and outer corner: Measured distance Required distance Required distance Measured distance Although the problem is reduced with a beam that uses a smaller measuring area, the error can not be completely eliminated. The most accurate solution to measure to tight corners and eliminate errors caused by beam divergence, is to use an offset measurement method such as that used in the field application software. Do the following: 1.
6 – Instrument Technology Offset measurement: Point 1 Point 2 Point 3 With offset measurements, you can accurately measure difficult locations in reflectorless mode and eliminate beam divergence errors. For more information, refer to the field application software documentation.
6 – Instrument Technology Tracklight Tracklight is a visible guide light that enables the rod holder to position themselves into the instruments current line of sight. The tracklight can be used during stakeout in all operational modes, and is also of great benefit when operating in robotic mode as a means of checking that the instrument is tracking, or when trying to reacquire lock by walking into the sight line of the LockNGo Tracker, or using the remote joystick control in robotic mode.
6 – Instrument Technology StepDrive Motor System and Focus System Spectra Precision FOCUS 35 Total Station is equipped with a StepDrive motor system to position the instrument and the telescope and a servo drive to focus the telescope. Due to the instrument accuracy it is important to use a high quality tripod and tribrach. It is also important to set up the tripod in a position for best stability, as shown. An unstable setup that could negatively influence the resulting measurement precision.
6 – Instrument Technology StepDrive The StepDrive motor system is a mechanical rough-fine drive system, which gives high turning speeds and accuracy. The system provides endless horizontal and vertical motion, including endless fine adjustment.
6 – Instrument Technology Focus System The instrument is equipped with a motor focus drive. The focus motion knob is on the side of the instrument for easy access. The focus knob is connected to a servo motor that is built into the telescope. When you turn the focus motion knob, the servo motor adjusts the focusing lens.
6 – Instrument Technology LockNGo Tracking Technology The Spectra Precision FOCUS 35 Total Station is equipped with an image based tracking system, which is used for robotic or conventional measurements to lock onto and track a prism.
