Applications
Once you entered all factors, the Focus 4W calculates the curve. If the curve
length (Len) is too large for a circle of the given radius, the curve is shortened.
Note – Press [DSP] to switch between display screens. See also page 90.
XYZ
Select this option to specify the stakeout point by coordinates.
1.
Press [4] or select XYZ in the Layout menu.
2.
Do one of the following:
3.
–
Enter the point name that you want to
establish and then press [ENT].
–
Specify the point by code or radius from the
Focus 4W. If several points are found, they
are displayed in a list. Press [^] or [v] to move
up and down the list. Use [<] to move up one
page, or [>] to move down one page.
Highlight a point in the list and then press [ENT].
The delta angle and the distance to the target are
shown.

To record the point, press [ENT]. The PT field
defaults to the specified PT + 1000.
Press [MENU] and then select Settings / Rec.
Use the Add Constant field to specify an integer.
The integer is added to the point number that is
being laid out to generate a new number for
recording the layout point. The default value is
1000. For example, when you stake out PT3 with
an Add Constant of 1000, the default value in the
SO field (layout record) is 1003.
The display then returns to the observation
screen. Press [ESC]. The display returns to the
PT/CD/R input screen. If you entered the
stakeout point using a single point name, the PT
defaults to the last PT + 1.

for recording new coordinate points.
Azimuth+HD input
To calculate a coordinate by an angle and distance
input from the base point (P1), press [1] or select HA+HD
from the Input menu.
Enter the base point, P1. Type the point name and press
[ENT].
Enter the azimuth, horizontal distance, and vertical

0.0000 is used.
A recording point screen with the calculated
coordinates appears. The PT field defaults to the last
recorded point + 1.
Press [ENT] to store the point.
Traverse
To calculate a new point based on two defined points
and the angle, horizontal and vertical distances from
the line defined by those two points, use the Traverse
(2Pt Angle) function.

Applications
To enter P1 and P2, enter point names or take
measurements to targets.
Enter the plus-minus angle, horizontal distance, and
vertical distance from the baseline defined by P1–P2.
If you do not enter a value in the dVD field, the value
0.0000 is used.
When you press [ENT] in the dVD field, a new point is
calculated. The name in the PT field defaults to the last
recorded point, + 1.
To record the new point and return to the point input
screen, press [ENT].
P1 (the base point) defaults to the previously recorded
point value. P2 defaults to the previous P1 value.
Tip – To continuously calculate a new point, enter +Ang, HD, and dVD from the previous
bearing line. This is a convenient way to enter Traverse points.
Entering coordinates
To manually enter the XYZ coordinates, press [3] or
select Input XYZ from the Input menu.
The PT name defaults to the last recorded PT + 1.
Enter the coordinates using the numeric keys. To move
to the next field, press [ENT] or [v] in a field.
To store the point as an MP record and return to the
point input screen, press [ENT] in the Z field. The default
PT is incremented to the next value.
You can record NE, NEZ, or Z-only data.

In the upper right corner of the screen, a counter
indicates how many points you have entered.
To input point numbers consecutively, use the Fr/To
softkey. See also Advanced feature: Entering a range of
points, page 83.
If you enter a new point name, you can enter new
coordinates and record the point. If you do not want to
record the point, press [ENT] without entering a value in
the PT field. An XY coordinate input screen appears.
Continue to enter points until you have defined all the
points in the lot. Then, press [v] to calculate the area and
perimeter.
The first and last points that you enter are joined to
close the area. You must enter the points in the order in which they define the lot. You
can enter up to 99 points.
Press [ENT] to exit from the function, or press [ESC] to
return to the previous screens one by one.
Advanced feature: Entering a range of points
To quickly enter a sequential range of points, use the
range input function. To access this function, select the
Fr/To softkey in the No. 01 or No. 02 input screens.
Enter the start point name in the Fr field and the end
point name in the To field. You can include letters and
hyphens in the point names, but the last character must
be numeric.

Curvature and refraction corrections
Because the surface of the earth is curved, the vertical difference (VD and Z) at the
measurement point, as referenced to the horizontal plane, inevitably includes some
error. This error is called curvature error. Also, because the density of the air
surrounding the earth decreases with altitude, light is refracted at different rates at
different altitudes. The error caused by this change in refraction is called refraction
error.

SS and F1 records
Raw SS and F1 records contain PT, HT, CD, HA, VA, and SD fields.
SS records are sideshots (topo shots). All shots taken from the Basic Measurement
Screen (BMS) are stored as SS records.
F1 records are backsight shots that are taken when you set up a station. Coordinates
are not available for an F1 record.
When you take more than one measurement to the same point and choose to
overwrite the XYZ data, the old raw record becomes raw data only. As a result, only
one SS (RAW) record keeps its corresponding SS(XYZ) record. Other SS(RAW) records
to the same point no longer have a record on their coordinates.

ST records
ST (station) records contain ST, HI, BS, and AZ fields.
Press [DISP] to switch between the screens:
•
The first screen shows ST, HI, BS, and AZ
•
The second screen shows X, Y, Z, PT, and CD
SO records
SO records are layout (L-O) shots. There shots are recorded in stakeout functions.
Press [DISP] to switch between the screens:
•
The first screen shows HA, VA, SD, PT, and HT
•
The second screen shows X, Y, Z, PT, and CD
•
The third screen shows dX, dY, dZ, PT, and CD
The dX, dY, and dZ fields store the difference between the actual position and the
planned position of the stakeout shot. These fields are downloaded as comment
records in Nikon RAW format.
CO records
A CO record is a comment that is added to the job by the system.
For example, the system writes a comment record
when you use the Remote Benchmark function to
change the Stn-Z, or when you use the BSCheck
function to reset the horizontal angle.
When you enter a Stn-XYZ by Base-XYZ function, the
recorded station appears as a comment record.

Editing station records
Note – The system will not recalculate measurements if you change the station record. You
will need to recalculate all coordinate and raw data that was collected from an edited
station record in your postprocessing software.

station record to edit. Then select the Edit
softkey.
2.
Use [^] or [v] to highlight a field. Then modify the
value in the selected field. You can edit any field
in the ST record, but the instrument does not
recalculate the measurements from this station.
3.
To finish editing, press [ENT] in the AZ field.
If you change the ST and HI values, the
coordinates of observation points are not recalculated. A comment record is
stored to record the change. The following is a comment record for a changed HI
value: CO, HI changed at ST:9012 Old HI = 1.3456m
If you change the BS or AZ values, raw records are not recalculated. A comment
record is stored to record the change.
