Instrument
Select the total station that will be used in the survey:
- Select the Manufacturer of the instrument.
- Select the Model of the instrument. Note that the models shown in the list correspond to the chosen type of survey.
Specify default values for prism rod height and instrument height:
- Foresight HR - rod height for the foresight prism.
- Backsight HR - rod height for the backsight prism.
- HI - the instrument height (measured from the instrument height mark to the ground point).
Note that height parameters you defined here can be changed later from any Survey or Stake screen in Optical mode by clicking
.
Connection Mode
Specify how the instrument is connected to the field controller:
- Initial TS Connection: Select Cable or Bluetooth TS.
Cable
Configure the settings necessary for your instrument to communicate with an external device connected via Cable:

Survey Settings - 1
Configuring the default settings for an optical survey:
- Select the Measurement Method of side-shot measurements: Direct or Direct/Reverse.
-
In the Tolerances panel, set the acceptable deviation values for the horizontal and vertical angles and the distance in the current units:
- Hz - horizontal angle;
- Dist. - distance;
- VA - vertical angle.
-
If required, select the Measure Reverse Dist check box to enable the reverse distance measurements in conventional and reflectorless surveys. These are used for the reduction of the distance measurement errors.
The option is available when the Direct/Reverse measurement method is selected.
Survey Settings - 2
Continue configuring the default settings for an optical survey:
- Measurement Type: select the order and the type of the measurements in one set:
- HA - horizontal angle;

Available for specific instruments only.
Select Prisms
To view and manage prism configurations available for selection and usage and to add and delete custom prisms.
- To review prism configurations and to select a new prism configuration to use in measurements:
- The list displays available prism configurations based on three types of prisms:
- predefined prism models (ATP1 360, A7 360, etc.);
- predefined generic prisms (0 Offset, -30 Offset, etc.);
- user-defined (custom) prisms - created by the user.
- Every prism configuration contains the prism parameters:
- Name - the prism's model or the name for generic or custom prism configurations.
- Constant - the Prism Constant (P.C.), parameter of the prism characterizing the difference between the reflection plane and the center of the prism.
- Hybrid Positioning™ antenna offset - is the offset between horizontal optical axis of the prism and antenna reference point (ARP).
- Height Type - the method how the height of the prism is measured in MAGNET Field.
- Center Offset - the distance from bottom of prism to its center.
- 360 Prism - indicates if a 360-degree prism is used in this configuration (Yes or No status).
- Aperture - the value for the reflector's aperture size in mm.
- The currently used prism configuration is marked with
near its name.
- Click on a prism configuration to highlight it and select it to use in measurements.
- Click
or
to change the position of selected prism configuration in the list.
- To view, add, edit, or delete specific prism configuration:
Note: Predefined prism configurations are non-editable and can't be deleted; you can only view prism details.
- Highlight a prism configuration and click the View / Edit button to open the Edit prism dialog and view the details of predefined prism configuration or view and edit the prism parameters for custom prism configuration.
- Click the Add button to open the Edit prism dialog, enter parameters of a new user-defined prism and create a custom prism configuration.

Click
to save the current prism configuration choice and return to the previous dialog. Click
to close the dialog without saving changes.
Edit Prism Configuration
To review the detailed information about selected prism; to create a new custom prism, or to modify the parameters of existing custom prism.
- Review detailed information about a selected prism:
- 360 Prism - if this check box is selected, it indicates that a 360-degree prism is used in the configuration.
- Aperture - the value for the reflector's aperture size in mm. In case of creating / editing a prism configuration, make sure that you input the correct value in this field. If incorrect aperture size is specified the tracking algorithms will produce errors.
- Create or edit a custom prism configuration:
- Specify the name of the prism for a new configuration.
- Enter or modify the prism parameters (described above) as necessary.
- Click
to save the prism configuration and return to the Prisms dialog. Click
to close the dialog without saving changes.
Stake Settings - 1
To configure settings for stakeout performed with the total station:
- Horizontal Distance Tolerance and Vertical Distance Tolerance: enter the distance tolerance values when the graph switches to a bull's eye in Stakeout.
- Compass Orientation to be used during the stakeout:
- Instrument Reference - the reference set in the instrument will be used;
- North - the top of the screen is oriented to the north during the stakeout session;
- Moving Direction - the top of the screen is oriented to the direction of moving during the stakeout session;
- Moving Dir + North - is similar to the Moving Direction option, but the screen will be oriented to the North direction when you are within three meters of the design point;
- Point/Azimuth - if you select this orientation type, the Orient Pt / Orient Az button will be displayed in the Stake Point dialog. Here you can define a point or an azimuth to orient the screen top.
- Display Reference: select an object that will be used in the Normal View mode as a reference orientation for the display.
- Include previous staked design points: if the check box is selected, you can select any design point in the Stake dialog for stakeout. This is, you can select not only a design point which was not used in the stakeout process yet, but also a design point for which a stakeout point was already measured.
Stake Settings - 2
To continue configuring settings for stakeout performed with the total station:
- Turn to Design Point: select the method for turning toward the design point.
Display options:
- Display HA only or Display HA/VA: the total station will display the computed values of angles to design points, and you will turn the instrument by these angles.
Grade Stake Marking
This dialog allows you to mark the grade stake with the skyward rounding of the cut/fill decimal values to an even number of feet (or meters).
To configure the marking settings:
- In the Working stake length field, enter the working length of the stake.
- In Top spacing field, enter a value of top reserve part of the stake for marking.
- In Bottom spacing field, enter a value of bottom reserve part of the stake for marking.
- In Cut/Fill interval field, enter an even number you want the cut/fill to round to.
Example:
If the cut is 0.8 and the bottom spacing is 0.5, we will round up to a cut of 2.0 (assuming the 1.0 interval) and place the mark at 1.2 above the ground; see below:
Staked Point Icon
Define how staked points will be displayed on the map:
- Select the Use icon for staked point check box to enable settings.
- In the Staked Point panel:
- Select the icon in from the Icon drop-down list select the icon appearance that will be reflected it in the window.
- Click
next to the Color field to select the color for the icon in the dialog.
The preview of icon appearance is displayed in the window.
Point Naming
Specify the parameters for naming a new point. When adding a new point, its name can be formed by using an increment or decrement to its sequential number, and adding prefixes or suffixes. You can form the names for all points in such a way, except for stacked points.
To configure point naming and other parameters, use the Point panel:
To set parameters for storing staked points, use the Staked Point panel:
- In the Name As field, select a method to set the number for
the first staked point. The initial point name can be set to:
- Design Point name.
- Next Point name.
- Design Pt Prefix (for example, "stk_01", where "stk_" is the prefix). The choice of the default prefix appears only when the corresponding item is chosen from the drop-down menu.
- Design Pt Suffix (for example, "01_stk", where "_stk" is the suffix). The choice of the default suffix appears only when the corresponding item is chosen from the drop-down menu.
- Design Pt+Constant. A specified numerical constant can be added to automatically generate the staked point name. For example, if the constant specified is "1000", and the design point number is "100", the staked point would be named "1100" (that is, 100+1000). If the design point number is alphanumeric, the constant is appended to the name. For example, for a design point named "ALPHA", the corresponding staked out point will be named "ALPHA1000".
- Range Start. Any start value of a range can be selected.
-
The Note can be set to either Design Point name, Design Pt Prefix, Design Pt Suffix, Station & Offset or None. If the Station & Offset option is selected, an edit box for entering an alphanumeric prefix is displayed, pre-filled with the default value:
- for the United States, this prefix is "Sta.";
- for the international markets the prefix is "SP.";
- for the Korean/Japanese markets the prefix is "NO."
With the Station & Offset option selected, depending on the choice of the prefix, MAGNET Field automatically generates one note for each stakeout point: "Sta.5+5.5R5.0", "SP.505.5R5.0", or "NO.5+5.5R5.0", respectively.
Miscellaneous
Customize the user interface configuration and program behavior during a survey:
- Display coordinates after measurement: when selected, computed coordinates are displayed automatically after a TS measurement is performed and before the point coordinates are stored into the database.
- Apply Earth Curvature and Refraction: when selected, the computed heights for Earth Curvature (Vertical Distance) and slope distances and vertical angles are corrected for atmospheric refraction.
- Prompt for Rod Height: when selected, a prompt for a height of the Rod (Target) appears before a point is stored.
- Right/Left Offset: Rod to TS: when selected, the right and left offsets are shown in the direction from Rod to TS.
- Stakeout Sound: when selected, a sound in Stakeout indicates as the point is staked.
- Beep on Storing Points: when selected, a sound beeps each time the point is stored.
- VA Zero at Level/Horizontal: this is not selected by default and VA is set to zero at Zenith. When the check box is selected, VA is set to zero at the Level/Horizontal direction. Only specific total stations allow MAGNET Field to set this value. For this reason, ensure that this option is set to the same value in the total station.
- Use Horizontal Angle Left: when selected, the horizontal angle measurements are shown in a counterclockwise (Left) direction. If this check box is not selected, the horizontal angle measurements are shown in a clockwise (Right) direction.
- Automatically display BS Setup screen: when selected, the Backsight Setup Dialog will be displayed automatically when you attempt to access any of the dialogs involving total station observations.
- Hold Offset Measurement: when selected, the dialog to measure an offset point with the help of the selected offset tool displays automatically after each measurement.
- Remember Occ/BS if set: when selected, you will not have to set the BS for total station observations once it has been set.
- Prompt for Traverse Advance: when selected, the prompt "Do you want to move the instrument now" displays when measuring traverse point. Click Yes to instantly open the Backsight dialog and select a new occupation point and backsight point. Click No to select a new occupation point and backsight point manually later.
