The instrument warns the operator immediately of any mislevelments in excess of ±5.5’ (±0.1 grads). Corrections for the horizontal angle, vertical angle, and slope distance are calculated in the field application software and applied to all measurements.

Pointing errors caused by slight misalignment of the instrument’s tracker have a similar effect to the HA and VA Collimation errors as detailed above.

  • Page 89: Correction For Trunnion Axis

    In the FOCUS 35 Total Station, 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.

  • Page 90: Distance Measuring Technology

    6   Instrument Technology Distance Measuring Technology Spectra Geospatial FOCUS 35 Total Stations are equipped with a combined distance unit. This means that the instrument can measure to a prism or to normal surfaces (reflectorless mode). The laser distance unit is based on the phase comparison method. The distance unit is coaxial with the line of sight and transmits an intensity modulated optical measuring beam that is reflected by a prism or scattered by a natural surface on which the beam is directed.

  • Page 91: Beam Divergence

    When observing measurements to a tight corner, the distance meter beam divergence introduces a range error caused by the size of the sampling area. Measuring to an inner and outer corner: FOCUS 35 Total Station User Guide | 91...
  • Page 92 2. Aim the instrument at the corner to store the correct horizontal and vertical angle. Offset measurement: 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. FOCUS 35 Total Station User Guide | 92...
