An LED in the trigger key indicates if the instrument is turned on. A solid light indicates on and a flashing light indicates suspend mode. When there is a Spectra Geospatial data collector running a field application software connected to the instrument, the trigger key performs the same function as the Enter key on the Spectra Geospatial data collector.
When there is no Spectra Geospatial data collector connected to the instrument, and you turn on the instrument using the trigger key, the face 2 display shows an electronic leveling screen. 1:250 Exit Setup For information on how to access the compensator menu and instrument setup menu from the face 2 display and keyboard, see Instrument Setup on page 24. Optical Plummet The instrument is equipped with an optical plummet, which has 2x magnification and a focusing range of 0.5 m to infinity.
As shown: • To focus the crosshairs, rotate the eye-piece. • To focus the optical plummet to the ground, push in or pull out the optical plummet. For information on how to adjust the optical plummet, see Adjusting the Optical Plummet on page 58. Handle The handle on the instrument is detachable for measurements in confined spaces, or for instances where the handle obstructs the sighting line.
The handle can be removed by: 1. Unscrew the two Torx screws securing the handle to the instrument, use a T30 Torx key. Removable handle screws 2. Slide the handle horizontally away from the front of the instrument.
Attaching the handle: Attaching the handle is completed by reversing the above operations. C 20 CAUTION - Make sure that the handle is firmly attached before you lift the instrument.
Set up Setup A stable setup is critical for high precision measurements. Setup Stability When an instrument is setup it is important to consider the following: 1. Set the tripod legs wide apart to increase the stability of the setup. A setup where one leg is placed on e.g asphalt and the other two on soil will still be a stable setup provided that the tripod legs are set wide enough.
Measurement Stability Take into account that instruments require sufficient time to adjust to the ambient temperature. The following rule-ofthumb for a high precision measurement applies: Temperature difference in degree Celsius (°C) x 2 = duration in minutes required for the instrument to adjust to the new temperature. Avoid sighting across fields with intense heat shimmer by sun light, e.g. at noon.

Compensator Calibration To calibrate the compensator, the instrument needs to be in perfect balance. After calibration, the compensator sensor will automatically adjust and allow for changes in that balance caused by the presence or the absence of an internal battery. To minimize imbalance in the instrument: • An internal battery must be present in the battery compartment. • The instrument handle must be attached. • The instrument will automatically position the telescope for best balance.

HA/VA Collimation and Trunnion Axis Tilt The instrument utilizes precise angle and distance measurements to determine the position of the point being measured. The instruments design facilitates the ability to measure all points with a single pointing to the target in the face 1 position.
The Horizontal and Vertical collimation and the trunnion axis tilt correction have been measured and stored in the instrument at the factory. In all calibrations, multiple sightings will be made in both faces to ensure that any minor pointing errors can be eliminated in the accurate determination of current collimation error values. In a new instrument the values should be close to zero, over time these will change. The instrument allows a maximum value of 0.05 grads (0.

Connecting a Data Collector To perform surveying with the instrument a data collector must be connected to the instrument running a field software. Connect with Long Range Radio The FOCUS 50 long range robotic model includes a long range radio (LRR). To connect to a Spectra Geospatial data collector, the channel and ID must match in both the instrument and the Spectra Geospatial data collector. The LRR is not available on Autolock or Short Range Robotic models.
Instrument Technology Angle Measuring Technology The principles of angle measurement are based on reading an integrated signal over two opposite areas of the angle sensor 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. • Trunnion axis tilt.
which eliminates the need to measure in both instrument faces. Carry out a collimation test in the following situations: • Whenever the instrument may have been roughly handled during transport. • When the ambient temperature differs by more than 10 °C (18 °F) from the previous collimation test. • Immediately prior to high precision angle measurements in one face.
Trunnion axis tilt error In the instrument, perform a pre-measurement trunnion axis tilt test to determine the trunnion axis tilt error. Angular measurements are observed in both instrument faces, the trunnion axis tilt error is calculated, and the respective correction value is stored in the instrument. The trunnion axis tilt correction value is then applied to a correction to the horizontal angle value and an automatic repointing of the telescope using SurePoint technology.
Averaging Measurements to Reduce Sighting Errors The instrument 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 Autolock. When Autolock is enabled, the instrument automatically locks onto and tracks the target. Manual sighting errors are reduced. • Automatically average angles during distance measurement. When measuring in Standard mode, the instrument takes approximately 1.
preset standard deviation value has been achieved. The default standard deviation value is 0.003m. Setting this value to a higher number gives shorter measurement time but is less accurate, especially when measuring to surfaces at greater distances or at oblique angles to the line of sight. • Weak Signal. This allows you to accept a DR measurement that is below the normal instrument specification.
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. With a smaller measuring area, these small objects can be easily missed. A smaller measuring area has advantages when measuring tight corners and vertices at close range. When observing measurements to a tight corner, the distance meter beam divergence introduces a range error caused by the size of the sampling area.
Measured distance Required distance Required distance Measured distance 67
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 eliminates errors caused by beam divergence, is to use an offset measurement method such as that used in the field application software: 1. Measure two points on the face of the building. 2.
Autolock Technology B The instrument is equipped with Autolock technology, which is used for a robotic or a conventional measurement with Autolock. Autolock technology controls the instrument servos and aims the instrument correctly towards the target. TIP – To assure maximum performance from the Autolock technology keep the lens clean and dry. The instrument can lock onto and track a prism. Aiming The adjustment between the two optical axes, the telescope and the tracker, may differ.
two axis have their own separate collimation data. It is however important to make collimation test for both axes. Manual aiming Autolock How to Check Aiming You can check how well the instrument is calibrated by measuring toward the prism with and without Autolock and compare the measured angles: 1. Aim manually at a prism and read out the horizontal and vertical angles. 2. Turn on Autolock and let the instrument lock on to the same prism automatically, read out the horizontal and vertical angles. 3.
left of the measuring beam, they will see a red flashing light; if they are to the right, they will see a green flashing light. B TIP – You can use the Tracklight for clearing sight lines and as an aid to find prisms in the dark or unfavorable sighting conditions. C CAUTION - Do not use the laser pointer as an aid when searching for prisms, the reflected light can dazzle your eyes. The reflected light will not damage your eyes, but might be uncomfortable.
slightly in an effort to compensate for that instability. An unstable setup that could negatively influence the resulting measurement precision. See Setup on page 21. Position Servo The servo technology is an electromagnetic direct drive system, which gives high turning speeds and accuracy. The frictionless motion removes servo noise and reduces instrument wear. The system provides endless horizontal and vertical motion, including endless fine adjustment.
Focus Servo The instrument is equipped with a focus servo. 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 integrated in the telescope. When you turn the focus motion knob, the servo motor adjusts the focusing lens. Focus motion knob Power Management The power management in the instrument can set the instrument to one of three different modes.
