screwdriver. And before transporting it, tighten the locking
screw to fasten the tribrach clamp in place so that it will not
shift on the tribrach.
• The handle of the instrument can be removed. When
operating the instrument with the handle attached, always
make sure that the handle is securely fixed to the
instrument body with the handle locks.
Precautions concerning water and dust resistance
The instrument conforms to IP65 specifications for waterproofing and dust resistance when battery
cover, connector cap and the external interface hatch are closed.
• Be sure to correctly attach the connector caps to protect the instrument from moisture and dust
particles when the connector is not in use.
• Make sure that moisture or dust particles do not come in contact with the terminal or connectors.
Operating the instrument with moisture or dust on the terminal or connectors 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.
• If there is a crack or deformation in the rubber packing for the battery cover or external interface
hatch, 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.
4
2. PRECAUTIONS
The Lithium Battery
• The lithium battery is used to maintain the 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.
Tribrach
• Always use the tribrach provided. During a traverse observation, it is recommended to use the same
type of tribrach for the target as well for accurate observations.
Backing up data
• Data should be backed up (transferred to an external device etc.) on a regular basis to prevent data
loss.
Other precautions
• Never place the instrument directly on the ground. Sand or dust may cause damage to the screw
holes or the centering screw on the base plate.

Bluetooth Wireless Technology

• Bluetooth function may not be built in depending on telecommunications regulations of the country
or the area where the instrument is purchased. Contact your local dealer for the details.
• Use of this technology must be authorized according to telecommunications regulations of the
country where the instrument is being used. Contact your local dealer in advance.
"28. REGULATIONS"
• TOPCON CORPORATION is not liable for the content of any transmission nor any content related
thereto. When communicating important data, run tests beforehand to ascertain that communication
is operating normally.
• Do not divulge the content of any transmission to any third party.
Radio interference when using Bluetooth technology
Bluetooth communication with the NET uses the 2.4 GHz frequency band. This is the same band used
by the devices described below.
•Industrial, scientific, and medical (ISM) equipment such as microwaves and pacemakers.
• portable premises radio equipment (license required) used in factory production lines etc.
• portable specified low-power radio equipment (license-exempt)
•IEEE802.11b/IEEE802.11g standard wireless LAN devices
The above devices use the same frequency band as Bluetooth communications. As a result, using the
NET within proximity to the above devices may result in interference causing communication failure
or reduction of transmission speed.
Although a radio station license is not required for this instrument, bear in mind the following points
when using Bluetooth technology for communication.

Regarding portable premises radio equipment and portable specified low-power radio
equipment:
• Before starting transmission, check that operation will not take place within the vicinity of
portable premises radio equipment or specified low-power radio equipment.
• In the case that the instrument causes radio interference with portable premises radio
equipment, terminate the connection immediately and take measures to prevent further
interference (e.g. connect using an interface cable).
• In the case that the instrument causes radio interference with portable specified low-power radio
equipment, contact your local dealer.

When using the NET in proximity to IEEE802.11b or IEEE802.11g standard wireless LAN
devices, turn off all devices not being used.
• Interference may result, causing transmission speed to slow or even disrupting the connection
completely. Turn off all devices not being used.

Do not use the NET in proximity to microwaves.
• Microwave ovens can cause significant interference resulting in communication failure. Perform
communication at a distance of 3m or more from microwave ovens.
14
4. PRODUCT OUTLINE

Refrain from using the NET in proximity to televisions and radios.
• Televisions and radios use a different frequency band to Bluetooth communications.
However, even if the NET is used within proximity to the above equipment with no adverse
effects with regard to Bluetooth communication, moving a Bluetooth compatible device
(including the NET) closer to said equipment may result in electronic noise in sound or images,
adversely affecting the performance of televisions and radios.
Precautions regarding transmission

For best results
• The usable range becomes shorter when obstacles block the line of sight, or devices such as
PDAs or computers are used. Wood, glass and plastic will not impede communication but the
usable range becomes shorter. Moreover, wood, glass and plastic containing metal frames,
plates, foil and other heat shielding elements as well as coatings containing metallic powders
may adversely affect Bluetooth communication and concrete, reinforced concrete, and metal will
render it impossible.
• Use a vinyl or plastic cover to protect the instrument from rain and moisture. Metallic materials
should not be used.
• The direction of the Bluetooth antenna can have adverse effects upon usable range.

Reduced range due to atmospheric conditions
• The radio waves used by the NET may be absorbed or scattered by rain, fog, and moisture from
the human body with the limit of usable range becoming lower as a result. Similarly, usable range
may also shorten when performing communication in wooded areas. Moreover, as wireless
devices lose signal strength when close to the ground, perform communication at as high a
position as possible.

• TOPCON CORPORATION cannot guarantee full compatibility with all Bluetooth products on the
market.

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.

10.TARGET SIGHTING
Offset
of Y direction
A target can be automatically sighted using the Auto Pointing function or manually sighted by the
operator using the sighting collimator and telescope.
When Auto Pointing is performed, the image sensor on the
Offset
instrument detects the light beam reflected from the target (prism
of X direction
or reflective sheet target), the offset between the target and
telescope reticle is calculated by image processing, then the angle
measurement value obtained from the encoder is compensated.
There is a possibility that the target and telescope reticle are not
aligned.
 Caution
• The instrument emits a laser beam until the prism is sighted.

• Auto Pointing can only be performed when a prism or sheet is used as the target. For reflectorless
measurement, the target must be sighted manually.
• Use designated reflective prisms/reflective sheets for higher precision measurement. Make sure
reflector type and aperture/sheet size are set correctly in <EDM configurations>.
• Detach the handle if the prism is located at the zenith.
"4.1 Parts of the Instrument Handle  Detaching/attaching the Handle"
• Auto Pointing may take long time if the prism is located at the zenith. In this case, use optional
accessory diagonal eyepiece (DE27) and manually sight the target.
"10.3 Manually Sighting the Target"
• If more than one prism is located in the field of sight during Auto Pointing, an operation error will
occur and the instrument will not be able to find the target.
• A prism beyond glass cannot be searched because a measurement error occurs.
• If an obstacle blocks the laser beam path between the instrument and the prism, instrument cannot
find the target correctly.
• If strong light shines directly into the objective lens, measurement cannot be performed correctly.
• Position every target in alignment with the objective lens to eliminate the error caused by tilted
target.

53
10. TARGET SIGHTING

AUTO AIM
When the target enters the field-of-view within the set limit for Auto Pointing completion (the limit
differs between "Fine" and "Rapid"), the instrument starts acquiring data (the amount of data
differs between "Fine" and "Rapid") then completes the Auto Pointing by calculating the data.
Set to "Fine" for greater accuracy during Auto Pointing. Make sure that the prism is securely
mounted on a tripod etc.
Set to "Rapid" when supporting the pole by hand.
When "Fine" is set the instrument checks that the prism position is stable, then searches for the
prism direction. Once the instrument confirms that the prism is sighted at the approximate center
of the field-of-view, Auto Pointing is complete. Although this setting provides greater accuracy,
when supporting the pole by hand, hand movements will result in Auto Pointing taking too long
to complete and a "Time out" error will occur.
When "Rapid" is set however, Auto Pointing can be performed even with slight instability of prism
position or minor shifts of target position in the field-of-view. The instrument will use the data
obtained to determine the direction of the target.
Auto Pointing performed using the "Rapid" setting can be completed in a much quicker time than
the "Fine" setting.
"Fine" is recommended when a high level of measurement accuracy is needed. The range for
the offset between the target and reticle after Auto Pointing completed changes as shown below
depending on the Srch. accuracy setting.
 Measure Acc.
This setting refers to internal operation of the Auto Pointing function.
In the "Advanced" setting, Auto Pointing movement before completion is constant. As a result,
Auto Pointing takes longer to complete depending on the target position, but sighting accuracy
is improved.
In the "Standard" setting, Auto Pointing movement is not constant, because the most direct way
to the target is chosen. That means the "Standard" setting enables Auto Pointing at a
comparatively faster speed than "Advanced".
In the "Advanced" setting, the offset between telescope reticle and the target center may larger
than that of "Standard".
 Srch method
Selects search before distance measurement option.
When set to "G.S." the instrument will search for the target in the area specified in the Search
area tab. When set to "R.C.", the instrument will wait for a Turning command to be issued from
the Remote Controller before starting Auto Pointing. Such commands can only be received
when using instruments have a beam detector for Remote Controller.
 TURN
This option allows the user to set a tolerance range for setting accuracy (after rotation to a
specified angle). For example, when this option is set to 30" and [INV], [H.ANG], or [ROTATE]
is pressed, the instrument will stop rotation within 30" of the specified rotation angle.
54
10. TARGET SIGHTING
 Search operation during Auto Pointing
When the target enters the field-of-view within the set limit (setting of "Auto AIM" and "Measure
Acc.") for Auto Pointing completion, the instrument stops moving, calculates the offset between
the target and telescope reticle by image processing, then compensates the angle measurement
value obtained from the encoder. This compensation enables accurate sighting in a short time.
Even though the target and telescope reticle may appear to be misaligned, actual angle value
of center of the target is displayed. Compensated values are displayed in blue.
If the instrument is rotated (manually or using the Jogs) more than 10", compensation will be
canceled, the angle reverts to that obtained from the encoder, and the angle values are once
again displayed in black. Compensation is automatically performed when performing Auto
Tracking. Terminating Auto Tracking or powering OFF the instrument will cancel the
compensation function.
2. Set the area in which to perform target sighting in
the Search area tab.
Angle values can only be specified in 1°steps.
Input values not conforming to this format will be
automatically rounded up.
Items set and options (*: Factory setting)
(1)Search pattern 
: 1*/2/3
(2) Vertical
: 0 to 90° (1*)
(3) Horizontal
: 0 to 180° (1*)
 Search pattern
The search pattern is the rotating method of telescope and
instrument to find the target prism in search mode.
In Pattern "1" instrument starts searching the prism at the point
where the prism is lost and gradually expands the searching area
in vertical direction, keeping the horizontal angular width.
Pattern "2" can be selected to search for the prism. The search
pattern tries to locate the prism in a very short time.
In pattern "3", instrument starts searching the prism at the point
where the prism is lost and gradually expands the searching area
in horizontal and vertical direction.
In every pattern, the searching is arranged to 2 times until the
reflector is found. The auto tracking mode changes to manual
mode when the reflector could not found out within 2 times
searching, and returns to the point where the reflector is lost.

Manually Sighting the Target

• 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. Focus on the reticle
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.
57
10. TARGET SIGHTING
2. Sight the target
Use the Sighting collimator to bring the target
into the field of view. Turn the vertical and
horizontal Jogs for fine sighting adjusting.
3. Focus on the target
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.
4. Readjust the focus until there is no parallax
Readjust the focus with the focussing ring until
there is no parallax between the target image
and the reticle.


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.
Sighting manually
When sighting manually, set "Track Setting" to "None" in <Motor Configuration> Configuration
tab, then use the Sighting collimator to bring the target into the field of view. When the target is
in the field-of-view, use the Jogs to make fine adjustments and accurately sight the center of the
prism.
It is recommended that a slow Jog turning speed is used for greater stability when performing
fine adjustments.
58
11.MEASUREMENT WITH AUTO TRACKING

half of the instrument rotate and target autosearch begins. When the target is found, the
target is aligned in the field-of-view and Auto
Tracking starts.
3. Press [TRK Off] in a Observation mode screen to
stop Auto Tracking.
• When [STOP] is pressed, distance
measurement will stop but Auto Tracking will
remain active.
 Lost Prism
In the event that an obstacle prevents the instrument sighting the target during Auto Tracking,
the instrument will predict the direction in which the target will travel and continue Auto Tracking
based on this prediction for the time period set in "Forecast time". If the instrument re-acquires
the target in this predicted direction, Auto Tracking continues without change. If the target is not
re-acquired however, the target is considered "lost" ("Target lost" status) and the instrument
starts "horizontal search", "Prism wait" and "re-search" in order. If the instrument re-acquires the
target in this process , Auto Tracking continues.
"Prism wait" will continue for the time period set in "Wait time".
If the target is not re-acquired after "re-search", sighting terminates. Start Auto Tracking
procedure again from step 1.
"Wait time" being set to "HOLD" (no limits), Auto Tracking procedure is as follows. The telescope
does not move and keeps "Prism wait" status and when the prism comes into the field of view,
the instrument starts Auto Tracking.

• 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.

• Make sure that the target setting on the instrument matches the type of target used. The instrument
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.
• Accurate measurement results cannot be obtained if the target is extremely dirty.
• During reflectorless measurement, if an object obstructs the light beam used for measurement or an
object with a high reflective factor (metal or white surface) is positioned 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.

15. RESECTION MEASUREMENT
 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.

The horizontal angle difference distance difference, and coordinate difference are calculated and
displayed using the following formulae.
Horizontal difference
Displayed value (angle)
= Horizontal angle of setting-out data - measured horizontal angle
Displayed value (distance) = measured horizontal distance x tan (horizontal angle of setting out data
- measured horizontal angle)
Slope distance difference
Displayed value (slope distance) * = measured slope distance - slope distance setting-out data
* Horizontal distance or height difference can be input in the above formula.
Coordinate difference
Displayed value (coordinates)* measured N setting-out coordinates - N coordinates of setting-out data
* E or Z coordinates can be input in the above formula
Height difference (REM setting out measurement)
Displayed value (height) = measured REM data - REM data of setting out data
• Setting out data can be input in various modes: slope distance, horizontal distance, height
difference, coordinates and REM measurement.
• It is possible to allocate softkeys in the Setting-out measurement menu to suit various applications
and the ways that different operators handle the instrument.

• 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)

The default setting is "On".
When this option is set to "Off", returned signal and ALC status are not checked. This setting
should be selected when performing distance measurement under conditions that would
normally result in a sighting error such as when using a small prism. However, if the sighting axis
strays from the center of the prism when set to "Off", accuracy is adversely affected. Always
perform Auto Pointing when the prism check option is set to "Off".

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 instrument 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, air pressure values and humidity, the atmospheric correction
value is calculated using the following formula and set into the memory.
For NET05AXII/1AXII
Atmospheric Correction Factor (ppm) =
0.294362 × p + 0.04127 × e

Ee = h × --------100
E = 6.11 × 10
( 7.5 × t )
---------------------------( t + 237.3 )
• The instrument measures the distance with a beam of light, but the velocity of this light varies
according to the index of refraction of light in the atmosphere. This index of refraction varies
according to the temperature and pressure. Near normal temperature and pressure
conditions:
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.
124
20. CHANGING THE SETTINGS
It is recommended that extremely precise instruments be used to monitor the air temperature
and pressure.
• Enter the average temperature, air pressure and humidity along the measurement beam route
in "Temperature", "Pressure" and "Humidity".
Flat terrain:Use the temperature, pressure and humidity at the midpoint of the line.
Mountainous terrain:Use the temperature, pressure and humidity at the intermediate point (C).
If it is not possible to measure the temperature, pressure and humidity at the midpoint, take such
measurements at the instrument station (A) and the target station (B), then calculate the average
value.

Additive Distance Constant
The additive distance constant K of the instrument 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.
152
22. CHECKS AND ADJUSTMENTS
3. Place the instrument at point C directly between
points A and B and set up the reflective prism at
point A.
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.

27.1
High Accuracy with the 360° Prism
Sighting can be more accurately performed by facing the 360° Prism toward the instrument. The 360°
Prism should be set up so that a pair of diametrically-opposed hexagonal points on its rubber flanges
are aligned with the sighting direction of the instrument (see the diagram below).
: Hexagonal points
When using the ATP1S, the 360° Prism should be set up so that a pair of diametrically-opposed marks
on top of the prism are aligned with the sighting direction of the instrument.

Manually Indexing the Vertical Circle by Face Left, Face Right
Measurement
The 0 index of the vertical circle of your instrument 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
1. Select “Obs.condition” in <Configuration>. Set “V
manual” (vertical circle indexing method) to “Yes”.
"20.1 Observation Conditions"
<V manual 0 set> is displayed.
2. Carefully level the instrument.
3. Accurately sight a clear target with a distance of
about 30m in the horizontal direction with the
telescope in face left.
Press [OK]. The vertical angle V2 is displayed
under "Take F2".
4. Turn the upper part through 180° and clamp it.
Then set the telescope in the face right position
and accurately sight the same target.
Press [OK].
The vertical and horizontal angles are displayed.
This concludes the vertical circle indexing
procedure.

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

Reflector Prescan
This function scans a user-defined range for targets and outputs approximate horizontal and vertical
angles for all targets found. This is particularly useful when sighting to targets currently without
coordinates, such as when there are numerous targets in the field-of-view at the initial stages of a
monitoring project, or when performing observation in tunnels etc. where low light conditions make
manual sighting difficult. More precise angle readings can be obtained by performing Auto Pointing
after Reflector Prescan.
