Usage precautions xxxx xxxxxxxxx

Surveying instruments are high-precision instruments. In order to assure that the Electronic

Total Station R-2500DN product which you have purchased will provide long-lasting

maximum

performance, the precautions in this manual must be followed. Make sure to follow these

instructions and use this product properly at all times.

[Solar observation]

WARNING

Never view the sun directly using the telescope as this may result in loss of sight.

Never point the objective lens directly at the sun as this may damage internal components.

When using the instrument for solar observation, be sure to attach the specially designed solar

filter (MU64) to the objective lens.

[Laser beam]

Do not stare into the laser beam. R-2500DN is a Class IIIa (3R) Laser product.

[EDM axis]

The R-2500DN EDM is the red visible laser beam and the beam diameter is very small.

The beam is emitted from the objective centre. The EDM axis is designed to coincide with the

telescope sight axis (but both axes may deviate slightly because of intense temperature

changes and a long time lapse).

[Target constant]

Confirm the Target Constant of the instrument before measurement.

If a different constant is to be used, use the correct constant of the target. The constant is

stored in the instrument's memory when turned off.

[Reflectorless and reflector sheet]

• Reflectorless

The measurement range and accuracy of the Reflectorless mode are based on the condition

that laser beam is emitted perpendicular to the white side of a Kodak Gray Card.

The measurement range may be influenced by the shape of the target and its environment.

There is a possibility that the range may vary when the target does not satisfy the

conditions above at survey work.

• There is a possibility that correct distance measurement may not be performed by

dispersion or reduction of laser beam when the laser beam comes into the target from a

diagonal angle.

• There is a possibility that the instrument may not be able to correctly calculate out the

distance when receiving reflected laser beam from forth and back directions in case of

measuring the target on the road.

• There is a possibility that synthesized values are calculated and the distance may become

longer or shorter than the actual one when the operator measures the target of slope or

sphere or rugged shape.

• There is a possibility that the instrument may not be able to correctly calculate out the

distance by collecting the reflected laser beam from a man or a car that comes and goes in

front of the target.

• There is a possibility that the distance may not be correctly measured when measuring a

target in the direction where there is a reflecting object (mirror, stainless board and white

wall, etc.) or under too strong sun light.

• In a situation high accuracy may not be expected, perform the measurement by Reflector

sheet or Prism.

• When using reflector sheet, set the reflector sheet to have its surface be approx. vertical to

the aiming line. If it is positioned not to be approx. right angle, there is a possibility that

correct distance measurements may be impossible by dispersion or reduction of laser beam.

In the following environments, the distance might not be able to be measured.

There is a reflection things (mirror, stainless board and white wall, etc.) in the direction of the

target and under too strong sun light

[Battery & charger]

• Do not use any battery or battery charger that is not approved by Pentax as it entails a risk

of damaging the instrument.

• If water should happen to splash on the instrument or the battery, wipe it off immediately

and allow it to dry in a dry location. Do not put the instrument in the case until it is

completely dry as this may result in damage to the instrument.

• Turn off the power when removing the battery from the instrument as removing the battery

while the power is still on may result in damage to the instrument.

• The battery mark displayed on the instrument is only an estimation of remaining battery

power and is not completely accurate. Replace the battery quickly when it is about to run

out of power as the time a battery lasts on one full charge differs depending on conditions

of ambient temperature, and the measurement mode of the instrument.

• Confirm the battery level remaining before operating.

[About Clock Battery (lithium)]

• Clock battery is a backup battery used for calendar clock function.

• The battery can last about five years with regular use, but it is possible to be shorter

depending on usage.

• When the voltage of the clock battery is low or runs out, the date and time display

incorrectly and indication of "Clock-batt. voltage low" will appear.

• Please contact your the dealer which the purchased was mail for any exchange or return of

the clock battery.

[LD POINT, laser pointer]

When you make a correct direction using the “LD POINT”, aim the laser beam at the wall and

mark the centre and then confirm the discrepancy between the reticle centre and the marked

point beforehand.

[Storage and operating environment]

• To prevent making short-circuit when removing the battery and charger from the case and

storing them, apply electrically resistant tape to the poles of the battery. Storing the battery

and charger as it may result in fire or burn injury due to short-circuit.

• Avoid storing the instrument in places subject to extreme high, low or radically fluctuating

temperature. (Ambient temperature range during use: –20° C to +50° C)

• Distance measurements may take longer when atmospheric conditions are poor such as

when heat shimmer occurs. When storing the instrument, always put it in its case and avoid

storage in dusty location or location subject to vibration or extreme heat or humidity.

• Whenever there is a sharp temperature difference between the instrument’s storage and

usage environment, allow the instrument to adjust to the environment for an hour or more

before using it. Make sure to protect the instrument from the sun if the location is subject to

intense direct sunlight.

• The battery should be charged approximately once per month if the instrument is to be

stored for an extended period of time. The instrument should also be removed from its case

occasionally and aired out.

• In addition to these precautions, be sure to handle the instrument properly at all times

following the descriptions given in the various sections of this manual to assure safe and

proper measurements.

[Transporting and carrying the instrument]

• Be careful to protect this instrument from shock of impact and excessive vibration which

may result in damage during transportation and shipment.

• When transporting the instrument, always put it in the case and wrap shock absorbing

material around it and be sure it is handled as “FRAGILE”.

[Checks and repairs]

• Always check the instrument before beginning work and check that the instrument is

maintaining the proper level of precision. Pentax bears absolutely no responsibility for

damages due to survey results obtained from surveys conducted without an initial

instrument check.

• Never disassemble the instrument, battery or charger, even if you do detect an abnormality,

as there is a risk of fire or electric shock due to short-circuit. If you think the product

requires repair, contact the retail outlet where you purchased it or an authorized repair site.

DCIM folder in the form of JPEG. The survey information is stored as a CSV file under the

name of INDEXDAT.CSV.

The numbers to be used for the file of the taken picture are from “P0000001.JPG” to

“P0009999.JPG”

The numbers for the picture taken file are from “P0000001.JPG” to “P0009999.JPG”. A new

folder of “101V300D” is created in the “DCIM” folder if a picture is taken when the number

“P0009999.JPG” has already been reached in the memory. A picture taken file is generated,

starting with the file name of “P0000001.JPG” in that new folder.

In the CSV file, the following cells are contained in this order. However, the stored

6. DISTANCE MEASUREMENT

6.1 Target setting

The target mode and its Constant of current setting

are shown at the left of the battery mark. For

example in case of each Constant 0, Reflectorless

(Non-Prism); N 0, Prism; P 0

Pressing [F2] [TARGET] changes the target mode.

• The target mode is changed sequentially as follows.

Reflector sheet - Prism - Reflectorless

• The selected target mode is stored in the memory even if the power is turned off.

So, next time you can use the same mode after turning on.

• The target Constant differs according to the selected target mode. So, confirm the target

mode and its Constant shown at the top screen after changing the target.

[Distance measurement by reflectorless (Non-Prism) mode]

• The measurement range and accuracy of Reflectorless are based on the condition that laser

beam is emitted perpendicular to the white side of the Kodak Gray Card.The measurement

range may be influenced by the shape of the target and its environment.There is a

possibility that the range may vary when the target does not satisfy the conditions above at

survey work.

• Pay attention to the following in case of distance measurement by Reflectorless.

In case of resulting in low accuracy, perform the distance measurement by Prism.

• The CODE number 521 [LONG RANGE MES.] shows ON/OFF.

• The WARNING (Laser Power) screen is displayed when Message ON is selected, and then

[F1] [MEAS] key is pressed.

• Pressing [F1] [MEAS] one time selects “Second MEAS setting” and twice selects “QUIT”.

①There is a possibility that correct distance measurement may be impossible by dispersion or

reduction of laser beam when the laser beam comes into the target from diagonal angle.

②There is a possibility that the instrument cannot calculate correctly when receiving reflected

laser beam from forth and back directions in case of measuring the target on the road.

③There is a possibility that synthesized values are calculated and the distance may become

longer or shorter than the actual one when the operator measures the target of slope or

sphere or rugged shape.

④There is a possibility that the instrument cannot calculate correctly collecting the reflected

laser beam from a man or a car that comes and goes in front of the target.

[Distance measurement by reflector sheet mode]

Position the Reflector sheet whose reflecting surface faces the aiming line to be approx.

Right angle when the distance is measured by it. If it is positioned not to be approx.

Right angle, there is a possibility that correct distance measurement may be impossible by

dispersion or reduction of laser beam.

[Applied measurement range by each target mode]

• When a wrong target mode is selected, a correct distance cannot be measured.

Please select a correct target mode and measure.

• It is sometimes possible to measure without prism under special conditions like in the close

distance, targeting on a wall surface. However, there is a possibility including some errors

in this case, so be sure to select the reflectorless mode.

• The target constant should be correctly selected and confirmed in case that the reflector

sheet is used at the prism mode and the prism is used at the reflector sheet mode.

6.2 Distance measurement

The R-2500DN has two distance measurement modes of primary MEAS and second MEAS.

Pressing the [F1] [MEAS] one time goes to MEAS and twice goes to second MEAS.

You can freely select and allocate your desired measurement mode in primary MEAS and

second MEAS by the Initial Setting 2. The “MEASURE SHOT” is set at primary MEAS and

“TRACK CONT” is set at second MEAS as a Factory default setting.

• MEASURE SHOT means the distance measurement by the shot mode.

• MEASURE CONT means the distance measurement by the continuous mode.

• TRACK SHOT means the fast distance measurement by the shot mode.

• TRACK CONT means the fast distance measurement by the continuous mode.

Confirm the target constant before beginning the distance measurement.

Example: “MEASURE SHOT”at primary MEAS (Factory default setting)

Collimate the telescope at a target and press the [F1]

[MEAS] once to start measuring the distance. Once

distance measurement has been started, the distance

measurement mark remains displayed. Upon

reception of a reflected light from the target, the

instrument beeps and displays the mark to start the

shot measurement automatically.

• If the instrument is in MODE B, press the [F5] [MODE] to switch to MODE A and press

[F1] [MEAS].

• Pressing the [F1] [MEAS] after collimating the telescope at the prism starts shot distance

measurement with the “MEAS” text blinking. Distance measurement is completed and the

“MEAS” text stops blinking the moment the distance measured by shot measurement is

displayed. During continuous measurement, the “MEAS” text keeps on blinking. Pressing

the [F1] [MEAS] again terminates both distance measurement and blinking the “MEAS”

text.

• Pressing [F4] [DISP] cycles through the sets of display items:“H.angle/H.dst./V.dst.”,

“H.angle/V.angle/S.dst.”, and “H.angle/V.angle/H.dst./S.dst./V.dst.”

• Pressing the [ESC] or [F2] [TARGET] or [F5] [MODE] during distance measurement

stops it.

• If the shot count for distance measurement has been set to 2 or more in “Initial Setting 2",

the distance is measured for the specified number of times to display the averaged value.

Example: “TRACK CONT” at second MEAS (Factory default setting)

Collimate the telescope at a Target and press [F1]

[MEAS] twice to start measuring the distance. Upon

reception of a reflected light from the target, the

instrument beeps and displays the mark to start the

TRACK distance measurement.

• If the instrument is in MODE B, press [F5] [MODE] to switch to MODE A and press [F1]

[MEAS ] twice.

• Pressing [F1] [MEAS] twice after collimating the telescope at the Target starts Continuous

distance measurement at fast speed with the “MEAS” text blinking.

It remains blinking during the measurement. If you press the [F1] [MEAS] again, Distance

measurement is completed and the “MEAS” text stops blinking.

• Pressing [F4] [DISP] cycles through the sets of display items:“H.angle/H.dst./V.dst.”,

“H.angle/V.angle/S.dst.”, and “H.angle/V.angle/H.dst./S.dst./V.dst.”

• Pressing the [ESC] or [F2] [TARGET] or [F5] [MODE] during fast distance measurement

stops it.

6.3 Quick mode

The Quick Mode is to shorten the measuring time

using prism or reflector sheet.

• The Quick Mode is effective to measure the distance up to 500m using prism or reflector

sheet.

• After selecting Quick Mode from the Quick Mode setting screen, the distance measurement

is done in Quick Mode.

• If the Quick Mode is selected, the distance measurement mark, "<-<- ->->", instead of

"((( )))", is displayed

The picture is taken after the end of distance measurement. Therefore, do not move the

telescope until the shot is completed.

You can sight the target approximately while looking at the View Mode screen, but you

cannot sight the target accurately since the telescope and the camare are not on the same

optical axis and both axis are not parallel. The optical axis of the telescope is always

positioned slightly below the centre of View mode screen. Make sure to use the camera

display for sighting the target approximately.

The optical system of the digital camera adopts the fixed focus method that doesn't request

focusing ,so that focusing of telescope doesn't synchronize with focusing the digital camera

on the image.

13.2 Atmospheric correction

The speed at which light travels through the air varies depending on the temperature and

atmospheric pressure. The R-2500DN is designed to measure distances at the speed of light in

order to measure accurately, atmospheric correction needs to be used. The instrument is

designed to correct for weather conditions automatically if the temperature and pressure are

input. Correction is then carried out based on the following formula.

K: Atmospheric Correction Constant

P: Atmospheric pressure (hPa)

t: Temperature(°C)

Distance after Atmospheric Correction D = Ds (1+K)

Ds:Measured distance when no Atmospheric Correction is used.

13.5 Atmospheric refraction and earth curvature correction

• Atmospheric refraction and earth curvature correction refers to correcting both the bending

of the light beam caused by atmospheric refraction and the effect on the height differential

and horizontal distance caused by the earth curvature.

• Correction called “atmospheric refraction and earth curvature correction” is initiated to

correct error when the slope distance and vertical angle are caused to determine the

horizontal distance and the height differential, with this instrument, the following formula

is used to correct these factors.

• Calculation formula when atmospheric refraction and earth curvature correction parameter

is set to “ON”:

Corrected horizontal distance (H)

Corrected vertical distance (V)

• Calculation formula when atmospheric refraction and earth curvature correction parameter

is set to “OFF”:

S: Slope distance

α: Vertical angle from horizontal

K: Atmospheric refraction coefficient (0.14 or 0.2)

13.6 Distance range

Generally speaking, the maximum range which can be measured varies considerably

depending on the atmospheric conditions. For this reason, the specifications illustrate the

values for both good and normal weather conditions.

It is extremely difficult to judge when weather conditions are “Good” and when they are

“Normal”. With this instrument, the conditions noted below are used to differentiate between

the two situations (good weather conditions for surveying are different from normal weather

conditions, and in surveying situations, cloudy skies are considered more favourable than

sunny skies.) .

Weather conditions for measurement ranges are based on the following standard values:

Normal : Visibility of approximately 20 km, with slight shimmer and moderate wind.

Good : Visibility of approximately 40 km, overcast, with no shimmer and moderate wind.
