Setting the measurement mode
The FOCUS 2 Series total station has two measurement modes:
•Prism mode (Prism) – See Measurement with a prism, page 32.
•Reflectorless mode (N-Prism) – See Measurement in Reflectorless mode, page 32.
These modes can be changed at any time by holding down the [MSR1] or [MSR2] key for one second. For
more information, see
To set the measurement mode depending on the target you want to measure, see the following
table.
Targ etTarg et sett i ng
Prism, reflector sheetPrism (Prism mode)
Other (reflective materials)N-Prism (Reflectorless mode)
In some cases, you can measure another target that is not appropriate to the set measurement
mode.
Note – The Focus 2 Series total station is Laser Class 3R in the Reflectorless mode and Laser pointer
function, and Laser Class 1 in the Prism mode.
1 Sec Keys, page 128.
CAUTION – Do not sight the prism when the laser pointer is on.
C
Measurement with a prism
Do not use a prism that is damaged, dirty, scratched, or chipped.
As the FOCUS 2 Series total station is extremely sensitive, multiple reflections on the prism surface
can cause a loss in accuracy.
Measurement in Reflectorless mode
The distance the FOCUS 2 Series total station can measure depends on the strength of the reflected
signal from the target. Target reflectivity, condition, and color all affect the distance measured.
Surfaces that have low reflectivity may not yield a measurement.
Setting the prism constant
To do this, hold down [MSR1] or [MSR2] for one second. For more
information, see 1 Sec Keys, page 128.
Note – If the prism constant is not 0 mm, then enter the prism
constant value directly into the Const field. For example, if the prism
constant is -30 mm, enter -30 mm into the Const field on the
instrument.

Tip – When you use the prism at a short distance, set the prism at a slight angle to the sighting
B
axis, rather than completely square.
Reflector prisms
When measuring distances using reflector prisms, a prism needs to be placed at the target place.
Reflector systems come with single prism and triple prisms, which can be mounted in a tribrach onto
a tripod or mounted onto a prism pole. Reflector systems can be self-configured by users according
to the job.
Mounting and dismounting the instrument
from the tribrach
Dismounting
If necessary, the instrument (including reflector prisms with the same tribrach) can be dismounted
from the tribrach. Loosen the tribrach locking screw in the locking knob with a screwdriver. Turn the
locking knob about 180°counter-clockwise to disengage anchor jaws, and remove the instrument
from the tribrach.

Face-1/Face-2 measurements
A measurement can be taken from either face of the instrument. To change the face, rotate the
instrument 180° on its base, and rotate the telescope 180° within the standard.
By averaging the Face-1 and Face-2 measurement values, most constant mechanical errors can be
cancelled out. Some errors, such as vertical axis error, cannot be cancelled out by averaging Face-1
and Face-2 measurements.
When rotating the telescope, take care not to catch a finger in the gap between the instrument’s
standard and the telescope.
A Face-1 measurement is made with the vertical circle positioned to the left of the telescope
eyepiece. A Face-2 measurement is made with the vertical circle positioned to the right of the
telescope eyepiece.

Multiple point resection
A resection sets up the station using angle/distance measurements to known points.
•A maximum of 10 points can be used in a resection.
•Measurements can be distance and angle, or angle only.
•Calculation starts automatically when enough measurements are taken.
•Poor observations can be deleted and recalculated if necessary.
•The minimum data required for a resection is either three angle measurements, or two distance
measurements.
Note – 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.
