2. PRECAUTIONS
Charging Battery
• Be sure to charge the battery within the charging temperature range.
Charging temperature range:
0 to 40°C
Warranty policy for Battery
• Battery is an expendable item. The decline in retained capacity depending on
the repeated charging/discharging cycle is out of warranty.
Tribrach Clamp
• When the instrument is shipped, the
tribrach clamp is held firmly in place
with a locking screw to prevent the
instrument from shifting on the
tribrachs. Before using the instrument
the first time, loosen this screw with a
screwdriver. And before transporting
it, tighten the locking screw to fasten
the tribrach clamp in place so that it will
not shift on the tribrachs.
Precautions concerning water and dust resistance
CX conforms to IP66 specifications for waterproofing and dust resistance when
the battery cover is closed and connector caps are attached correctly.
• Be sure to close the battery cover and correctly attach the connector caps to
protect the CX from moisture and dust particles.
• Make sure that moisture or dust particles do not come in contact with the inside
of the battery cover, terminal or connectors. Contact with these parts may cause
damage to the instrument.
• Make sure that the inside of the carrying case and the instrument are dry before
closing the case. If moisture is trapped inside the case, it may cause the
instrument to rust.
• Do not press the speaker hole using something with a pointed tip. Doing so will
damage an internal waterproof sheet, resulting in a degraded waterproof
property.
• If there is a crack or deformation in the rubber packing for the battery cover, stop
using and replace the packing.
• To retain the waterproof property, it is recommended that you replace the rubber
packing once every two years. To replace the packing, contact your local dealer.
5
2. PRECAUTIONS
The Lithium Battery
• The lithium battery is used to maintain the CX Calendar & Clock function. It can
back up data for approximately 5 years of normal use and storage (Temperature
= 20°, humidity = about 50%), but its lifetime may be shorter depending on
circumstances.
Vertical and horizontal clamps
• Always fully release the vertical/horizontal clamps when rotating the instrument
or telescope. Rotating with clamp(s) partially applied may adversely affect
accuracy.
Backing up data
• Data should be backed up (transfered to an external device etc.) on a regular
basis to prevent data loss.
Other precautions
• If the CX is moved from a warm place to an extremely cold place, internal parts
may contract and make the keys difficult to operate. This is caused by cold air
trapped inside the hermetically sealed casing. If the keys do not depress, open
the battery cover to resume normal functionality. To prevent the keys from
becoming stiff, remove the connector caps before moving the CX to a cold
place.
• Never place the CX directly on the ground. Sand or dust may cause damage to
the screw holes or the centering screw on the base plate.
• Do not aim the telescope directly at the sun. Also, attach the lens cap to the
telescope when not in use. Use the Solar filter to avoid causing internal damage
to the instrument when observing the sun.
"34.2 Optional accessories"
Protect the CX from heavy shocks or vibration.
Never carry the CX on the tripod to another site.
Turn the power off before removing the battery.
When placing the CX in its case, first remove its battery and place it in the case
in accordance with the layout plan.
• Consult your local dealer before using the instrument under special conditions
such as long periods of continuous use or high levels of humidity. In general,
special conditions are treated as being outside the scope of the product
warranty.

2. PRECAUTIONS
Maintenance
• Always clean the instrument before returning it to the case. The lens requires
special care. First, dust it off with the lens brush to remove tiny particles. Then,
after providing a little condensation by breathing on the lens, wipe it with the
wiping cloth.
• If the display unit is dirty, carefully wipe it with a soft, dry cloth. To clean other
parts of the instrument or the carrying case, lightly moisten a soft cloth in a mild
detergent solution. Wring out excess water until the cloth is slightly damp, then
carefully wipe the surface of the unit. Do not use any alkaline cleaning solutions,
alcohol, or any other organic solvents, on the instrument or display unit.
• Store the CX in a dry room where the temperature remains fairly constant.
• Check the tripod for loose fit and loose screws.
• If any trouble is found on the rotatable portion, screws or optical parts (e.g.
lens), contact your local dealer.
• When the instrument is not used for a long time, check it at least once every 3
months.
"33. CHECKS AND ADJUSTMENTS"
• When removing the CX from the carrying case, never pull it out by force. The
empty carrying case should be closed to protect it from moisture.
• Check the CX for proper adjustment periodically to maintain the instrument
accuracy.

•
•
The charger will become rather hot during use. This is normal.
Do not use to charge batteries other than those specified.
The charger is for indoor use only. Do not use outdoors.
Batteries cannot be charged, even when the charging lamp is flashing, when
the temperature is outside the charging temperature range.
Do not charge the battery just after charging is completed. Battery performance
may decline.
Remove batteries from the charger before putting into storage.
When not in use, disconnect the power cable plug from the wall outlet.
Store the battery in a dry room where the temperature is within the following
ranges. For long-term storage, the battery should be charged at least once
every six months.
Storage period
Temperature range
1 week or less
-20 to 50°C
1 week to 1 month
-20 to 45°C
1 month to 6 months
-20 to 40°C
6 months to 1 year
-20 to 35°C
• Batteries generate power using a chemical reaction and as a result have a
limited lifetime. Even when in storage and not used for long periods, battery
capacity deteriorates with the passage of time. This may result in the operating
time of the battery shortening despite having been charged correctly. In this
event, a new battery is required.

8. FOCUSSING AND TARGET SIGHTING

• When sighting the target, strong light shining directly into the objective lens may
cause the instrument to malfunction. Protect the objective lens from direct light
by attaching the lens hood.
Observe to the same point of the reticle when the telescope face is changed.
PROCEDURE
1. Look through the telescope
eyepiece at a bright and
featureless background.
Turn the eyepiece screw
clockwise, then counterclockwise
little by little until just before the
reticle image becomes focussed.
Using these procedures, frequent
reticle refocussing is not
necessary since your eye is
focussed at infinity.
2. Loosen the vertical and horizontal
clamps, then use the sighting
collimator to bring the target into
the field of view. Tighten both
clamps.
3. Turn the telescope focussing ring
to focus on the target.
Turn the vertical and horizontal
fine motion screws to align the
target with the reticle.
The last adjustment of each fine
motion screw should be in the
clockwise direction.

8. FOCUSSING AND TARGET SIGHTING
4. Readjust the focus with the
focussing ring until there is no
parallax between the target image
and the reticle.

30
Eliminating parallax
This is the relative displacement
of the target image with respect to the reticle when the observer’s head is
moved slightly before the eyepiece.
Parallax will introduce reading errors and must be removed before
observations are taken. Parallax can be removed by refocussing the reticle.

• Target type
• Prism constant correction value
• Atmospheric correction factor
• EDM ALC
"31.1 Configuration -Config Mode-"/"31.2 EDM Settings"
 CAUTION
• When using the Laser-pointer function, be sure to turn OFF the output laser
after distance measurement is completed. Even if distance measurement is
canceled, the Laser-pointer function is still operating and the laser beam
continues to be emitted. (After turning ON the Laser-pointer, the laser beam is
emitted for 5 minutes, and then automatically switches OFF. But in the Status
screen and when target symbol (ex.
) is not displayed in the OBS mode, the
laser beam is not automatically turned off.)

• Make sure that the target setting on the instrument matches the type of target
used. CX automatically adjusts the intensity of the laser beam and switches the
distance measurement display range to match the type of target used. If the
target does not correspond to the target settings, accurate measurement results
cannot be obtained.
• Accurate measurement results cannot be obtained if the objective lens is dirty.
Dust it off with the lens brush first, to remove minute particles. Then, after
providing a little condensation by breathing on the lens, wipe it off with the
wiping cloth.
• During reflectorless measurement, if an object obstructs the light beam used for
measurement or an object is positioned with a high reflective factor (metal or
white surface) behind the target, accurate measurement results may not be
received.
• Scintillation may affect the accuracy of distance measurement results.
Should this occur, repeat measurement several times and use the averaged
value of the obtained results.
37
11. DISTANCE MEASUREMENT
11.1 Returned Signal Checking
• Check to make sure that sufficient reflected light is returned by the reflective
prism sighted by the telescope. Checking the returned signal is particularly
useful when performing long distance measurements.

• When the light intensity is sufficient even though the center of the reflective
prism and the reticle are slightly misaligned (short distance etc.), “*” will be
displayed in some cases, but in fact, accurate measurement is impossible.
Therefore make sure that the target center is sighted correctly.

Precaution when performing resection
In some cases it is impossible to calculate the coordinates of an unknown
point (instrument station) if the unknown point and three or more known
points are arranged on the edge of a single circle.
An arrangement such as that shown below is desirable.
: Unknown point
: Known point
It is sometimes impossible to perform a correct calculation in a case such
as the one below.
When they are on the edge of a single circle, take one of the following
measures.
(1) Move the instrument station
as close as possible to the
center of the triangle.
(2) Observe one more known
point which is not on the circle
(3) Perform a distance
measurement on at least one
of the three points.

• In some cases it is impossible to calculate the coordinates of the instrument
station if the included angle between the known points is too small. It is difficult
to imagine that the longer the distance between the instrument station and the
known points, the narrower the included angle between the known points. Be
careful because the points can easily be aligned on the edge of a single circle.
67
13. COORDINATE MEASUREMENT
By performing coordinate measurements it is possible to find the 3-dimensional
coordinates of the target based on station point coordinates, instrument height,
target height, and azimuth angles of the backsight station which are entered in
advance.
• EDM setting can be done in coordinate measurement menu.
Setting items: "31.2 EDM Settings"
PROCEDURE 3-D Coordinate Measurement
The coordinate values of the target can be found by measuring the target based
on the settings of the instrument station and backsight station.
The coordinate values of the target are calculated using the following formulae.
N1 Coordinate = N0 + S x sinZ x cosAz
E1 Coordinate = E0 + S x sinZ x sinAz
Z1 Coordinate = Z0 + S x cosZ + ih - th
N0: Station point N coordinate
E0: Station point E coordinate
Z0: Station point Z coordinate
S: Slope distance ih: Instrument height
Z: Zenith angle
th: Target height
Az: Direction angle

Z (zenith angle) is calculated as 360° -Z when the telescope is in the face 1
position.

14. SETTING-OUT MEASUREMENT
Setting-out measurement is used to set out the required point.
The difference between the previously input data to the instrument (the settingout data) and the measured value can be displayed by measuring the horizontal
angle, distance or coordinates of the sighted point.
The horizontal angle difference and distance difference are calculated and
displayed using the following formulae.
Horizontal angle difference
dHA = Horizontal angle of setting-out data - measured horizontal angle
Distance difference
Distance
Displayed item
Sdist: S-O S = measured slope distance - slope distance of setting-out data
Hdist: S-O H = measured horizontal distance - horizontal distance of settingout data
Vdist: S-O V = measured height difference - height difference of setting-out
data
• Setting out data can be input in various modes: coordinates, horizontal
distance, slope distance, height difference and REM measurement.
• In slope distance, horizontal distance, height difference, and coordinate mode,
registered coordinates can be recalled and used as setting-out coordinates. In
slope distance, horizontal distance and height difference, S/H/V distances are
calculated from the read in setting-out coordinate, instrument station data,
instrument height, and target height.
• EDM settings can be set in the Setting-out measurement menu.
• If not measured or the space is left blank “Null” will be displayed.
If distance or angle of setting-out data is set to “Null” the Distance difference is
automatically set to “Null”

• If the S-O data is set in the display other than <S-O Coord>, when the display
is returned to <S-O Coord>, the data that has been input will be deleted.

19. OFFSET MEASUREMENT
Offset measurements are performed in order to find a point where a target cannot
be installed directly or to find the distance and angle to a point which cannot be
sighted.
• It is possible to find the distance and angle to a point you wish to measure
(target point) by installing the target at a location (offset point) a little distance
from the target point and measuring the distance and angle from the survey
point to the offset point.
• The target point can be found in the five ways explained below.
19.1 Single-distance Offset Measurement
Finding it by entering the horizontal distance from the target point to the offset
point.
• When the offset point is positioned to the left or right of the target point, make
sure the angle formed by lines connecting the offset point to the target point and
to the instrument station is almost 90°.
• When the offset point is positioned in front of or behind the target point, install
the offset point on a line linking the instrument station with the target point.
PROCEDURE
1. Set the offset point close to the
target point and measure the
distance between them, then set
up a prism on the offset point.

...
P5 (N5, E5, Z5)
• Number of specified coordinate points: 3 or more, 50 or less
• Surface area is calculated by observing the points on a line enclosing an area
in order or reading in the previously registered coordinates in order.

• If two or less points are used to measure an area, an error will occur.
• Be sure to observe (or recall) points on an enclosed area in a clockwise or
counterclockwise direction. For example, the area specified by entering (or
recalling) point names 1, 2, 3, 4, 5 or 5, 4, 3, 2, 1 implies the same shape.
However, if points are not entered in numerical order, the surface area will not
be calculated correctly.
 Slope area
The first three points specified (measured/read-in) are used to create the
surface of the slope area. Subsequent points are projected vertically onto
this surface and the slope area calculated.

23. TRAVERSE ADJUSTMENT
Measurement of a traverse begins with observation of the backsight station and
foresight station. The instrument station is then moved to the foresight station and
the previous instrument station becomes the backsight station. Observation is
performed again at the new position. This process is repeated for the length of the
route.
This adjustment function is used to calculate the coordinates of such a sequence
of consecutively-observed points (traverse points and points observed from
traverse points (see P3-1 to P3-3 below)). When calculation is complete, the CX
displays the precision of the traverse and, when necessary, traverse adjustment
can be performed.

Adjustment methods
Adjustment is applied to results for traverse points and points observed from
traverse points.
Adjustment methods and distribution options selected in step 8 are
described below.
Method
Compass: The Compass method distributes the coordinate error in
proportion to the length of the traverse lines.
L
TL
Northing adjustment = ------- × closure north
Easting adjustment =
L
------- × closure east
TL
Where: L =length of the traverse line to the point
TL = sum of the traverse line lengths
Transit:
The Transit method distributes the coordinate error in proportion
to the northing and easting ordinates of each traverse line.
ΔN
Northing adjustment =| --------------- × closure north
Σ ΔN
Easting adjustment =
Where: ΔN =
ΔE =
Σ|ΔE| =

--------------- × closure east
Σ ΔE
change in northing for the traverse line
change in easting for the traverse line
Σ|ΔN| = sum of the absolute value of all the
changes in northings of all the traverse lines
sum of the absolute value of all the changes in
eastings of all the traverse lines
Angular adjustment
Weighted: Any angular closure is distributed among the angles of the
traverse route based on the sum of the inverses of the forward
and back traverse line lengths at each angle. The backsight and
foresight lines are considered to have infinite lengths
for the purposes of this weighting computation.

Linear:
Any angular closure is distributed evenly among the angles of the
traverse route.
None:
No angular adjustment performed.
Elev adjustment
Weighted: Any closure in the elevations is distributed in proportion to the
length of the traverse line leading to the point (like the Compass
method for coordinate adjustment).
Linear:
Any closure in the elevations is distributed evenly in each leg of
the traverse route.
None:
No elevation adjustment performed.

Horizontal distance (H Dist)
The CX calculates the horizontal distance using the slope distance.
There are the following 2 ways to display the horizontal distance data.
Ground:
The distance that reflects neither the Sea level correction factor nor the
Scale factor.
Grid:
The distance in the plane rectangular coordinates system that reflects the
Sea level correction and Scale factors (or the distance in the plane
rectangular coordinates system that reflects the Scale factor only, when
"No" is set for "Sea level crn".)

• The horizontal distance data recorded in this instrument is the ground distance
only, and the displayed value changes according to the settings for the
horizontal distance. When reviewing the observation data in the TOPO menu,
set "Horizontal distance" and "Scale factor" so that the intended value is
displayed.
225
31. CHANGING THE SETTINGS
• If horizontal distance is requested when selecting "T type" or by the GTS
command, uncorrected "ground distance" is output, regardless of the Sea level
correction or Scale factor setting.

Automatic tilt angle compensation mechanism
The vertical and horizontal angles are automatically compensated for small
tilt errors using the 2-axis tilt sensor.
• Read the automatically compensated angles when the display has
stabilized.
• The horizontal angle error (vertical axis error) fluctuates according to the
vertical axis, so when the instrument is not completely leveled, changing
the vertical angle by rotating the telescope will cause the displayed
horizontal angle value to change.
Compensated horizontal angle = Measured horizontal angle + Tilt in angle
/tan (Vertical angle)
• When the telescope is directed close to the zenith or nadir angle, tilt
compensation is not applied to the horizontal angle.
Collimation correction
The CX has a collimation correction function that automatically corrects
horizontal angle errors caused by horizontal axis and leveling axis errors.
Normally set this item to "Yes".
Sea level correction
The CX calculates horizontal distance using slope distance values. As this
horizontal distance does not take height above sea level into consideration,
performing spherical correction is recommended when measuring at high
altitudes. Spherical distance is calculated as follows.
R
( HDg ) = ------------------- × HD
(R + H)
Where:R = radius of the spheroid (6371000.000m)
H= averaged elevation of the instrument point and target point
HDg=Spherical distance
HD = horizontal distance
*1 The averaged elevation is automatically calculated from the instrument
point elevation and the collimation point elevation.

adjusted if an error occurs as a result of the amount of light received. Set to
"Free" when the target is moved during measurement or different targets
are used.
• When "Hold" is set, the amount of light received will not be adjusted until
initial adjustment has been performed and continuous measurement
completed.
• Try setting to "Hold" when the light beam used for measurement is stable
but is frequently obstructed by obstacles such as people, cars, or tree
branches etc. preventing measurement from being performed.

• When the distance measurement mode is set to "Tracking" (target is
moving during distance measurement), the distance will be measured in
"Free" status regardless of the EDM ALC setting.

Atmospheric correction factor
The velocity of the light beam used for measurement varies according
atmospheric conditions such as temperature and air pressure. Set the
atmospheric correction factor when you wish to take this influence into
account when measuring.
• The CX is designed so that the correction factor is 0 ppm at an air pressure
of 1013 hPa, a temperature of 15°C, and a humidity of 50%.
• By inputting the temperature and air pressure values, the atmospheric
correction value is calculated using the following formula and set into the
memory. (humidity is regarded as 50%)
Atmospheric Correction Factor (ppm) =
0.04127 × e

E = 6.11 × 10
With constant pressure, a temperature change of 1°C: an index change of
1 ppm.
With constant temperature, a pressure change of 3.6 hPa: an index change
of 1 ppm.
To perform high accuracy measurements, it is necessary to find the
atmospheric correction factor from even more accurate temperature and
pressure measurements and perform an atmospheric correction.
It is recommended that extremely precise instruments be used to monitor
the air temperature and pressure.
• Determine the temperature and pressure as follows.
Flat terrain
:Use the temperature and pressure at the midpoint of
the line.
Mountainous terrain :Use the temperature and pressure at the
intermediate point (C).
If it is not possible to measure the temperature and pressure at the midpoint,
take the temperature and pressure at the instrument station (A) and the
target station (B), then calculate the average value.
Average air temperature :(t1 + t2)/2
Average air pressure
:(p1 + p2)/2
• If the weather correction is not required, set the ppm value to 0.

31.3 Allocating Key Functions
It is possible to allocate the softkeys in OBS mode to suit the measurement
conditions. It is possible to operate the CX efficiently because unique softkey
allocations can be preset to suit various applications and the ways that different
operators handle the instrument.
• The current softkey allocations are retained until they are revised again, even
when the power is cut off.
• It is possible to register two sets of key function allocations: user setting 1 and
user setting 2.
• It is possible to recall the softkey arrays registered for User 1 and User 2 as
necessary.

• When softkey allocations are recorded and registered, the previously recorded
key settings are cleared. When a softkey array is recalled, the key array is
changed to the key array that has been recalled, clearing the previous key
array. Be sure to remember this.
 The following are the softkey allocations when the CX was shipped.

33. CHECKS AND ADJUSTMENTS
33.6 Additive Distance Constant
The additive distance constant K of the CX is adjusted to 0 before delivery.
Although it almost never deviates, use a baseline with a known distance precision
to check that the additive distance constant K is close to 0 several times a year
and whenever the values measured by the instrument begin to deviate by a
consistent amount. Perform these checks as follows.

• Errors in setting up the instrument and reflective prism or in sighting the target
will influence the additive distance constant. Be extremely careful to prevent
such errors when performing these procedures.
• Set up so that the instrument height and the target height are identical. If a flat
place is not available, use an automatic level to make sure the heights are
identical.
PROCEDURE Check
1. Find an area of flat ground where
two points 100m apart can be
selected.
Set up the Instrument at point A
and the reflective prism at point B.
Establish a point C half way
between points A and B.
2. Precisely measure the horizontal
distance between point A and
point B 10 times and calculate the
average value.
3. Place the CX at point C directly
between points A and B and set
up the reflective prism at point A.
256
33. CHECKS AND ADJUSTMENTS
4. Precisely measure the horizontal
distances CA and CB 10 times
each and calculate the average
value for each distance.
5. Calculate the additive distance
constant K as follows.
K = AB - (CA+CB)
6. Repeat steps 1 to 5 two or three
times.
If the additive distance constant K
is within ±3mm even once,
adjustment is unnecessary.
If it always exceeds this range,
have our service representative
perform an adjustment.

36. EXPLANATION
36.1 Manually Indexing the Vertical Circle by Face 1,
Face 2 Measurement
The 0 index of the vertical circle of your CX is almost 100% accurate, but when it
is necessary to perform particularly high precision angle measurements, you can
eliminate any inaccuracy of the 0 index as follows.

• If the power is cut off, the vertical circle indexing is ineffective. Do it again every
time the power is turned on.
PROCEDURE
Manually indexing the vertical circle
1. Select “Obs. condition” in Config
mode. Set “V manual” (vertical
circle indexing method) to “Yes”.
2. Press [OBS] on the status screen.
The electric circular level is
displayed in the screen.
OK
3. Carefully level the instrument and
press [OK].
The vertical angle V1 is displayed
under “Take F1.”
4. Accurately sight a clear target with
a distance of about 30m in the
horizontal direction with the
telescope in face 1.
Press [OK]. The vertical angle V2
is displayed under “Take F2.”

5. Turn the upper part through 180°
and clamp it. Then set the
telescope in the face 2 position
and accurately sight the same
target.
Press [OK].
The vertical and horizontal angles
are displayed.
This concludes the vertical circle
indexing procedure.

36. EXPLANATION
36.2 Correction for refraction and earth curvature
The instrument measures distance, taking into account correction for refraction
and earth curvature.
Distance Calculation Formula
Distance Calculation Formula; with correction for refraction and earth curvature
taken into account. Follow the Formula below for converting horizontal and
vertical distances.
Horizontal distance D = AC(α)
Vertical distance Z = BC(α)
D = L{cosα - (2θ - γ) sinα}
Z = L{sinα + (θ - γ) cosα}
θ = L • cosα/2R
g = K • Lcosα/2R
K = 0.142 or 0.2
R = 6371km
