You can enter the following into the Focus 4 total station:
•
A point name or number, see page 50
•
A code, see page 53
Entering a point name or number
You can use numeric or alphanumeric names up to 20 characters long to identify
points.
The default name for a new point is the last point name entered, with the last digit
incremented. For example, if the last point name was A100, the default name for the
next point is A101.
If the last character of the previous point name is alphabetic, the default point name is
identical to the last point name.
When the cursor is in a PT (point) field, there are several ways to specify a point, or to
enter coordinates. You can:
50
•
Enter an existing point, see page 51
•
Enter a new point, see page 51

for the point in NE, NEZ, or elevation-only (Z) format.
To store the point in the current job, press [ENT] on the
last line (the CD field).
Pressing [ENT] without a point name
To use a point without recording the coordinates, press
[ENT] in a PT field, without entering a point name.
The input coordinates are used in the calculation but
they are not saved in the database. The message This
PT will not be recorded appears.
Specifying a wildcard (*)
If you include an asterisk ( for example, A100*) when you enter a point or code name, a
list of points that match the entered text appears.
Use [^] or [v] to move the cursor to the point that you
want to use. Then press [ENT].
If the Page Up icon appears, you can use it to move up
one page on the list. You can also use [<].

Measuring distances
WARNING – Never look at the sun through the telescope. If you do, you may damage or
lose your eyesight.
WARNING – Precautions should be taken to ensure that persons do not look directly, with
or without an optical instrument, into the beam.
WARNING – Laser beam path should be located well above or below eye level wherever
practicable.

Taking a distance measurement
To take a distance measurement, press [MSR1] or [MSR2] in the Basic Measurement Screen
(BMS) or in any observation screen.
While the instrument is taking a measurement, the prism constant appears in a
smaller font.
If tracking is set to ON, measurements are taken
continuously until you press [MSR1], [MSR2], or [ESC]. Each
time a measurement is taken, the distance is updated.
To change the height of target (HT), temperature, or
pressure, press [HOT]. See also [HOT] button, page 46.
Settings that relate to corrections (T-P corr, Sea Level,
C&R corr., and Map projection) are included in the job
settings and are job-specific. To change any of these
settings, you must create a new job. See also Job
settings, page 93, and Settings (basic job settings),
page 96.

Getting Started
Target field
•
If the measurement is started with the Target
field set to Prism, there is a dash “–” in front of
the prism constant.
•
If the measurement is started with the Target
field set to N-Prism, there is a right square
bracket “]” in front of the prism constant.
The symbol then continuously moves from left to right over the prism constant in
the display.
The Target setting is used by the Focus 4 total station to apply better cyclic-error
adjustment in distance measurement. 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.

You 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.
Tip – 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.

Tip – 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.
