When you have finished the measurement, press [ENT] to go to the point recording screen.5. Enter the point or code name and then press [ENT].When you move the cursor to a field, the current or default value appears in inverted colors. (It appears as white text on a black background). This is the default Replace All input mode.To change the input mode to Overwrite and highlight the first character, press [>]. To move the cursor to the end of the string, press [<].Entering a point from the point stackThe point stack is a list of the last 20 point names used, in chronological order from last used to first used. To enter a point from the point stack: 1. Select the Stack softkey when the cursor is in the PT field. The stack appears.2. Press [^] or [v] to move the cursor to the point that you want to use.3. Press [ENT].When you return to the point input screen, the selected point name is entered in the PT field, incremented by one. For example, if you selected the A101 point, A102 appears in the PT field.

If you highlight a layer in the list and then press [ENT], the codes and layers in that layer are displayed.When you return to the input screen, the selected code is entered in the CD field.Advanced feature: Searching for a code using the first characterItems are shown in alphabetic order. To find a code quickly when the code list appears, use the first-character search. For example, to see feature codes that begin with T, use the keypad to enter the letter T (press [1] twice).After each button press, the input mode field displays the selected letter. For example, if you press [1], S appears. If you quickly press [1] again, T appears. If you do not press the [1] button again, the letter T is selected.Once you select a letter, the cursor moves to the feature code beginning with that letter.If there is no code beginning with that letter, the cursor moves to the next available letter.Entering values in feet and inchesIf US Survey Feet (US-Ft) or International Feet (I-Ft) is selected as the distance unit, you can enter and display distances, HIs, HTs, and coordinate values in decimal feet or in feet and inches. See also Unit, page 99, and Other settings, page 101.To enter values in feet and inches in an input screen, enter the elements, separated by periods (.), in the following format:The default denominator is 16.

The target setting efficiently eliminates multipath reflection.An incorrect Target setting may result in measurements outside the precision and intervals specified for the instrument.If a prism target is aimed in N-prism mode, the warning message Signal High!→Try Prism Mode is displayed because of the excessive light reflection.A measurement made immediately after changing the target setting may take longer than usual.

Spectra Precision Focus 4 Total Station User Guide 65Applications 4You can use a maximum of 10 points in a resection. Measurements can be distance and angle, or angle only. Calculation starts automatically when enough measurements are taken.You can delete poor observations and recalculate if necessary. You can also select the BS point. BTip – If the angle between known point 1 and known point 2 (measured from the station point) is extremely acute or extremely oblique, the resulting solution will be less reliable geometrically. For geometric reliability, select known point locations (or station point locations) that are widely spaced.1. To start the resection, press [2] or select Resection in the Stn Setup menu.2. Enter the point name for the first observation point (PT1).3. Enter the target height and press [ENT].4. Sight PT1 and press [MSR1] or [MSR2].5. To proceed to the next point, press [ENT].6. Enter the second point (PT2) and its height of target.

Measure to PT2 and press [ENT].When the instrument has enough data, it calculates the station (STN) coordinates.–If more than the minimum required data is available, a standard deviation screen appears.–To take measurements to strengthen geometry of the resection, press the Add softkey. For information about the View softkey, see Advanced feature: Viewing and deleting a measurement in resection, page 67.8. When the results are satisfactory, record the station. To do this, press [ENT] or the REC softkey.9. Enter the height of instrument, if required. Press [ENT]. The ST field defaults to the last recorded PT + 1. 10. To change the station name, move to the ST field and edit or replace the text.BTip – If you have set Split ST to Yes, the ST field defaults to the last recorded ST value + 1. BS defaults to the first observed point.11. To change the BS, press the Change softkey.12. Select the BS point that you want to use and press [ENT].13. To finish the resection setup, move the cursor to the BS field and press [ENT].
Spectra Precision Focus 4 Total Station User Guide 67Applications 4BTip – The minimum data required for a resection is either three angle shots, or one angle shot and one distance shot. If you use a distance shot, the distance between the target points must be greater than the measured distance. Stn-Z is calculated from distance-measured data. If no distances are measured, then Stn-Z is calculated using angle-only measurements to points with 3D coordinates.Advanced feature: Viewing and deleting a measurement in resectionTo check the measurements to each known point, press the View softkey on the calculated STN (sigma or coordinate) screen.To delete a measurement (because of large sigma values, for example), highlight the measurement data or display the detail screen for the measurement. Then press the DEL softkey. The STN coordinates are automatically recalculated.To continue resection observations, press the Add softkey. The input screen for the next PT appears.Base XYZSelect this option to change the instrument XYZ values.Base XYZ does not store an ST record in the job, so the BS Check cannot check the backsight if you enter a station using the Base XYZ option.You can use this function without an open job. 1.
