FOREWORD
Thank you for purchasing the TOPCON Total Station CTS-1. For the best performance of the instru-
ment, please carefully read these instructions and keep them in a convenient location for future
reference.
GENERAL HANDLING PRECAUTIONS
1. Use care to avoid shock to the instrument.
Always provide some cushioning material to minimize risk of shock during transportation. If ex-
posed to heavy shock, the instrument cannot be expected to function properly when measuring.
2. When carrying the instrument,
Always remove the instrument from its tripod when carrying at the site. Hold the instrument bottom
and support in your hands. If it must be carried with the tripod attached, never carry the instrument
horizontally over the shoulder. Always keep the instrument in a vertical position when carried.
3. Do not expose the instrument to direct sunlight for long periods.
A Never leave the instrument in extreme heat longer than necessary. It could adversely affect its
: performance. Never expose the instrument without a filter to direct sunlight. It may damage the
components inside the instrument.
4. Any sudden change of temperature to the instrument or prism may result in a reduction of measur-
Ing distance range, i.e when taking the instrument out from a heated vehicle.
5. Check the battery indicator.
Be sure to check the battery for voltage level before using the instrument.
6. When using the high power transceiver.
Keep the high power transceiver away from the instrument,

2 PREPARATION FOR MEASUREMENT
2.1 Leveling the Instrument
Level and center the instrument correctly to insure the best performance.
Use tripods with a tripod screw of 5/8 in. diameter and 11 threads per inch, such as the Type
E TOPCON wide-frame wooden tripod.
Reference
Leveling and centering the instrument
1. Setting Up the Tripod
First. extend the extension legs to suitable lengths and tighten the screws on their midsections.
2. Attaching the Instrument to the Tripod Head
Place the instrument carefully on the tripod head and align the tripod screw with the socket
on the base of the instrument. When aligned, screw in the tripod screw until the instrument
is fixed securely on top of the tripod head.
3. Leveling the Instrument |
The circular level is used for initial rough leveling which is then refined with the plate level.
e Centering the Circular Level
1) Use the two furthest leveling screws, or A and B, to move the bubble of the circular level.
In other words, rotate the screw in opposite direction as indicated by the arrows which
will shift the bubble of the circular level. The bubble is now located on a line
perpendicular to a line running through the centers of the two leveling screws being
adjusted.
2) Next, revolve the remaining leveling screw, or C, as noted, to shift the bubble to the
center of the circular level.
if the bubble cannot be centered properly, repeat the leveling operations from the beginning.

e The battery operating time will vary depending on the environmental conditions as an ambient tem-
perature, charging time, the number of times of charging and discharging etc. It is recommended
for safety to charge the battery beforehand or to prepare spare full-charged batteries to go out with.
e The display of remaining battery capacity shows the battery power level at its mode. The safety
condition indicated in the angle measurement mode does not necessarily assure the battery's
ability to be used in the distance measurement mode. it may happen that the mode change from
the angle mode to the distance mode will stop the operation because of the sufficiency of the
battery power for the distance mode which consumes more power than the angle mode.
e Note that the EDM unit is working when “O set” at the power on, which shows as an easy battery
check before use. |

OTHER FUNCTIONS
Buzzer Sounding and Display for Every Vertical 90°
When the horizontal angle falls in the range of less than 1° of 0°, 90°, 180°, or 270°, the buzzer
sounds and the H mark goes on and off continuously. And they are stopped only when the
horizontal angle is adjusted to 0900007, 909%00700”, 180%00/00”, or 270%00'00”.
® [tis possible to set the buzzer not to sound previously. For the setting method, see “8. SELECT-
ING MODE.”
Auto Power Off (APF ON/OFF)
If no key operation is given or no process of measurement is performed for more than 30 minutes
(No change exceeding 30” has occurred during angle measurement), the power turns off
automatically.
Or no change in distance exceeding 10cm has occurred during distance measurement, the
mode changes to angle measurement automatically in case that the instrument does not operate
for approximately 10 minutes, and the power turns off more than approximately 20 minutes after
that.
e /t is possible to stop the auto power off function. See “8. SELECTING MODE.”
Lighting for the Reticle and the Indicator
The lights for the reticle and the indicator are lit up by pressing the C5) key, and they go off
by pressing the C+> key again. In addition, they go off automatically 30 seconds after they are
lit up.
6. ATMOSPHERIC CORRECTION AND PRISM CONSTANT
6.1 Atmospheric Correction
The velocity of light through air is not constant but depends on the atmospheric temperature and
pressure, which makes it necessary to correct for the ambient atmospheric temperature and
pressure in order to obtain distance measurements of high accuracy.
An atmospheric correction system is built into the instrument and, therefore, the displayed
distance measurements are automatically corrected when the required correction is stored into
the memory of the instrument from the keyboard.
In the instrument, the temperature and the atmospheric pressure are automatically corrected by
entering them directly from the keyboard.
6.2 Use of Atmospheric Correction Chart (Reference)
The atmospheric correction value is obtained with the atmospheric correction chart, in the
following manner:
1) Measure the ambient temperature and pressure at both instrument position and prism reflector
position. Average the results.
| CAUTION: The thermometer and ‘barometer should not be exposed directly
to the |
2) Locate the measured temperature on the horizontal scale of the atmospheric correction chart.
3) Locate the measured pressure on the vertical scale of the atmospheric correction chart.
4) Find the intersection of the measured temperature and pressure on the chart and read the PPM
(parts per million) value from the diagonal line, which will be the required atmospheric
correction.
Example
The measured temperature is ............... ... .. FE еено, + 26%
The measured pressure is... LL 0 760mmHg
Therefore,
The correction value is... еее + 10ppm

6.3 Atmospheric Correction Calculation
The atmospheric correction Ka and the distance after correction L can also be obtained in the
following manner. First, the atmospheric correction value Ka is obtained from the following
formula:
_ _ 1060xp 6
Ка = (279.6 - 579 5 | )x 10
when,
P: Ambient atmospheric pressure (mm Hg)
t Ambient atmospheric temperature (°C)
Then the distance after correction L is obtained from the following formula:
L= £ (1+Ka) (M),
? = Distance measured with the instrument, when Ka =0 (ppm).
(Example)
When the atmospheric temperature is 20°C, the atmospheric pressure 635mmHg and the
measured distance 1,000.000m, the atmospheric correction value Ka and the distance after
correction L are obtained with the following calculations:
106.0 x 635

6.4 Prism Constant
The prism constant for TOPCON prisms is O. If the prism of other manufacturers than TOPCON
is used, the appropriate constant shall be set beforehand.
The constant is kept in the memory even after power is shut off.

9. ADJUSTMENTS
All TOPCON instruments have undergone strict and rigid inspections and should, therefore, arrive
properly adjusted, unless subject to excessive rough handling during transportation. The instrument
will, of course, lose adjustment when used under the adverse conditions normally prevailing on most
sites and in the field, thus requiring adjustment.
Check the instrument from time to time, but especially before important surveying operations in the
field, as it may prove expensive to duplicate the operation once more. Be absolutely certain that
adjustments are required before making such adjustment but, on the other hana, try to carry out the
required adjustments before the instrument gets badly out of adjustment, as the adjustments may have
to be repeated several times then.
9.1 Adjustment of the Optical Axes
To check if the optical axes of EDM and theodolite are matched, follow the procedure below. It
is especially required after adjustment of the eyepiece reticle is carried out.
1) Position the EDM and prism with 2m between them.
pH _ approx. 2m ——
2) Sight through the eyepiece and focus to the prism by turning the focusing knob. Then, align
the center of prism with the center of the target.
e Prism
|
3) Turn the power ON. Then set the instrument S/A mode or continuous distance measurement
mode. |
4) Sight through the eyepiece and focus to the blinking red light spot by turning the focusing knob
in the direction of infinity. ВЕ
N
х\
| x E light spot
N.
5) If displacement of the reticle cross-hairs is within one-fifth of the diameter of the round red spot,
both vertically and horizontally adjustment will not be required.
9.2 Checking Accuracy of the Distance Measurement
The accuracy of the distance measurements should be checked, at least, once every six months,
in order to maintain high accuracy at all times. Use a standard measured distance of known
accuracy of an accurately measured distance of more than 20 meters (65.5 ft) for this purpose.
The accuracy of the checking procedure will depend entirely on the accuracy of the measured
distance, in this case.
Any discrepancy from the true distance will be the additional offset compensation factor (in
millimeters) which must be added or subtracted from the offset compensation factor set to the
Instrument by the factory. Thus, it will become the new offset compensation factor which should
be set to the instrument.
For comparative measuring when no authorized standard primary length is obtained:
Provide an arbitrary point C on an almost horizontal straight line that is about 100 m long and
connects Point A with B and measure the straight lines AB, AC, BC.
Instrument constant = AC + BC — AB
вер ев
Note: Any Errors in installing the instrument and prisms or incorrect slope reduction and sighting
will affect checking accuracy. Use care to avoid errors when the instrument constant is
changed. (See “9.11 How to Set the Instrument Constant”)
9.3 Pointers on Adjustment
1) Adjust the eyepiece of the telescope properly prior to any checking operation which involves
sighting through the telescope. Remember to focus properly, with parallax completely
eliminated. |
2) Carry out the adjustments in the order listed, as the adjustments are dependent one upon
another. Adjustments carried out in the wrong sequence may even nullify previous adjustments.
3) IÍ “Adjustment of the Vertical Cross-Hair” only is required, this adjustment should be followed
oy “Adjustment of Vertical Angle 0 datum” and “Collimation of the Instrument”, as well as
“Adjustment of the Optical Axes”.
4) If “Collimation of the Instrument” only is required, this adjustment should be followed by
“Adjustment of the Optical Axes” and “Adjustment of Vertical Angle 0 datum”.
5) IÍ the instrument is badly out of adjustment, make rough adjustments initially and then repeat
them once more, as this procedure will usually prove more efficient than trying to make the
final adjustment from the beginning. |
6) Always conclude adjustments by tightening the adjustment screws securely (but do not tighten
them more than necessary, as you may strip the threads, twist off the screw or place undue
stress on the parts). Furthermore, always tighten by revolving in the direction of tightening
tension. | |
7) The attachment screws must also be tightened sufficiently, upon completion of adjustments.
8) Always repeat checking operations after adjustments are made, in order to verify results,
24
9.4 Adjustment of the Vertical Cross-Hair
Adjustment is required if the vertical cross-hair is not In a plane perpendicular to the horizontal
axis of the telescope (since it must be possible to use any point on the hair for measuring
horizontal angles or running lines).
1) Set the instrument up on the tripod and carefully level it.
2) Sight the cross-hairs on a well-defined Point A at a distance of, at least, 50 meters (160 ft.) and
clamp all horizontal motions.
3) Next, swing the telescope vertically, with the vertical screw, and check whether the point travels
along the length of the vertical cross-hair.
4) If the point appears to move continuously on the halr, the vertical cross-hair lies in a plane
perpendicular to the horizontal axis (and adjustment is not required). |
5) However, if the point appears to be displaced from the vertical cross-hair, as the telescope is
swung vertically, adjustment is required In the reticule plate.
6) Unscrew the cross-hair adjustment section cover, by revolving it in the counterclockwise
direction, and take it off. This will expose four eyepiece section attachment screws, as well as
four capstan cross-hair adjustment screws.
Eyepiece section
attachment screw.
7) Loosen all four attachment screws slightly with the accessory screw-drive (while taking note of
the number of revolutions). |
Then, revolve the eyepiece section so that the vertical cross-hair is coincided to Point A. Finally,
re-tighten the four screws by the amount that they were loosened. |
8) Check once more and if the point travels the entire length of the vertical cross-hair, further
adjustment is not required. |

9.5 Adjustment of the Plate Level
Adjustment 1s required if the axis of the plate level is not perpendicular to the vertical axis.
1) Place the plate level parallel to a line running through the centers of two leveling screws, say,
A and B.
Use these two leveling screws only and place the bubble in the center of the plate level vial.
Leveling screw A, Leveling screw B.
Plate level vial
2) Next, revolve the instrument 180° or 200 g around the vertical axis and check bubble move-
ment of the plate level.
If the bubble has been displaced, then proceed with the following adjustment.
3) Adjust the level adjustment capstan screw, with the accessory adjusting pin and return the
bubble towards the center of the plate level vial. However, correct only one-half of the displace-
ment by this method.
4) Correct the remaining amount of the bubble displacement with the leveling screws.
5) Revolve the instrument 180° or 200 g around the vertical axis once more and check bubble
movement. If the bubble is still displaced, then repeat the adjustment.

9.6 Adjustment of the Circular level
Adjustment is required if the axis of the circular level is also not perpendicular to the vertical axis.
1) Carefully level the instrument with the plate level only.
2) If the bubble of the circular level is also centered properly, at this time, adjustment is not
required. Otherwise, proceed with the following adjustment.
3) Shift the bubble to the center of the level, by adjusting three capstan adjustment screws on the
bottom surface of the circular level, with the accessory adjusting pin.

4) Adjustment is completed with the above.
a
9.7 Collimation of the Instrument
Collimation is required to make the line of sight of the telescope perpendicular to the horizontal
axis of the instrument, as otherwise, it will not be possible to extend a straight line by direct means.
1) Set the instrument up with clear sights of about 50 to 60 meters (160 ~ 200 ft.) on both sides
of the instrument.
2) Level the instrument properly with the plate level.
3) Sight Point A at approximately 50 meter (160 ft) distance and tighten all clamps.
4) Loosen the vertical clamp only and plunge the telescope 180° or 200 g around the horizontal
axis, so that the telescope is pointed in the opposite direction.
5) Sight Point B, at equal distance as Point A, and tighten the vertical clamp.
6) Loosen the upper motion clamp and revolve the instrument 180° or 200 g around the vertical
axis. Fix a sight on Point A once more and tighten the upper motion clamp.
7) Loosen the vertical clamp only. Plunge the telescope 180° or 200 g around the horizontal axis
once more and fix a sight on Point C, which should coincide with the previous Point B. Tighten
the vertical clamp.
8) If Points B and C do not coincide, adjust in the following manner.
9) Unscrew the cross-hair adjustment section cover, |
10) Find Point D at a point between Points C and B, which should be equal to 1/4th the distance
between Points B and C and measured from Point C. This is because the apparent error
between Points B and C is four times the actual error since the telescope has been reversed
twice during the checking operation.
1) Shift the vertical cross-hair line and coincide it with Point D, by revolving the left and right
capstan adjustment screws with the adjusting pin.

9.8 Adjustment of the Optical Plummet Telescope
Adjustment is required to make the line of sight of the optical plummet telescope coincide with
the vertical axis (as otherwise the vertical axis will not be in the true vertical when the instrument
is optically plumbed).
* Optical Plummet Telescope
1) Coincide the center mark and the point.
2) Revolve the instrument 180° or 200 g around the vertical axis and check the center mark. If
the point is properly centered in the center mark, adjustment is not required. Otherwise, adjust
in the following manner,
3) Unscrew the adjustment section cover of the optical plummet telescope eyepiece, by revolving
it in the counter-clockwise direction, and take it off This will expose four capstan adjustment
screws which should be adjusted with the accessory adjusting pin to shift the center mark to
the point. However, correct only one-half of the displacement in this manner,
Note: Adjust in the same manner as for “Colimation of the Instrument. |
4) Next, use the leveling screws and coincide the point and center mark.
5) Revolve the instrument 180° or 200 g around the vertical axis once more and check the center
mark. If it is coincided to the point, then further adjustment is not required. Otherwise, repeat
the adjustment.

9.9 Other Adjustments
1) If the leveling screws become loose and slack, tighten the two adjustment screws on top of
each of the leveling screws for obtaining porper tension. |
2) Should there be any slack between the leveling screws and the base, loosen the setscrew of
the holding ring and tighten the holding ring with the adjusting pin, until it is properly adjusted.
Re-tighten the setscrew on completing the adjustment.

o PRECAUTIONS WHEN CHANGING OR STORING
BATTERIES
The capacity of battery will be affected and its service life shortened in any of the following cases while
it Is recharged, discharged or stored.
1. Recharging
Fig. 1 shows how ambient temperature at recharging is related to charging efficiency or as affecting
discharge capacity. As seen from the figure, charging at normal temperature is best, and the ef-
ficiency decreases as the temperature rises. It is best, therefore, to always recharge the battery at
normal temperature to obtain full use of battery capacity and enjoy maximum operation per charge.
And the service life of your battery will be shortened if it is frequently overcharged or recharged
at high temperature.
Note: 0. 10 charge means that the St IS“ > recharged v with 0.1 time current as > agar inst ts
- capacity. Se ES Ce RE RASE ET RENE Pape EEE CE Pie,
2. Discharge
Fig. 2 shows discharge temperature characteristics. Discharge characteristics at high temperature
are the same as those at normal temperatures. The battery is likely to have reduced discharge
capacity as well as lower discharge voltage when discharged at low temperature. And the service
ie of your battery will be shortened If it is greatly overcharged.
Note: 1c discharge: means one with 1 time current over battery capaci ty: о Ш
: }
3. Storage
See Fig. 3 for how storing period at different temperature levels is related to the remaining y capacity
The battery will lose its capacity as storage temperature rises and the storage period increases. This
does not mean, however, that the battery performance is damaged when the battery is stored. The
battery, reduced in-capacity, will be restored once it is recharged. Always recharge your battery
before use. And recharge and discharge the battery 3 or 4 times to restore its capacity if it has been
stored for a long period or at high temperature. Storing at high temperature can adversely affect
the service life of your battery. |
You battery has been fully charged before leaving the factory, but its capacity may be affected
considerably when it takes several months to reach you, if it is stored at high temperature area or
