    • From slant height: the instrument height is calculated from the slant height from the TPS side marker to the reference point.

    • From keyboard height: the instrument height is calculated from the slant height from the TPS keyboard to the reference point.

    • From reference point: the instrument height is calculated measuring a reference point.

Calculate instrument height from slant height

  • Measure the slant height on the TPS side marker. The instrument height is calculated using the reference width.

  • Select From slant height.

    • TPS model: brand and model of the active profile.

    • TPS reference width (R): the TPS reference width. This value is entered by the software on known models.

    • Slant height (S): slant height.

    • Instrument height (H): calculated instrument height.

Calculate instrument height from keyboard height

  • Measure the slant height to the bottom border of the keyboard. The instrument height is calculated using the offset values.

    • TPS model: brand and model of the active profile.

    • Keyboard horiz. offset (R): horizontal distance from the center of the telescope to the bottom border of the keyboard. This value is entered by the software on known models.

    • Keyboard vert. offset (O): vertical distance from the bottom border of the keyboard to the center of the telescope. This value is entered by the software on known models.

    • Slant height (S): slant height.

    • Instrument height (H): calculated instrument height.

Calculate instrument height from reference point

  • Measure a reference point with a known elevation to calculate the instrument height.

    • Station elevation: current elevation of the station.

    • Reference value: select:

      • Reference point: requires either the coordinates of a known point or pointing the telescope to and measure a known point.

      • Reference elevation: requires pointing the telescope to a known point with the desired elevation.

    • Point: reference point for the calculation. Tap to access to the options.

    • Elevation: shows or sets the reference elevation according to the set reference value.

    • Instrument height (H): calculated instrument height.
