Usage precautions

Surveying instruments are high-precision instruments. In order to assure that the Electronic Total Station V-200 series product which you have purchased will provide long-lasting maximum performance, the precautions in this manual must be followed. Be 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. V-200 is a class-II Laser product.

[EDM axis]

The V-200 series 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]

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.

10

•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 prism.

[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.

[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. Be sure to protect the instrument from the sun if the location is subject to intense direct sunlight.

•During surveys for which the survey precision or atmospheric measurement method has been defined, measure the atmospheric temperature and pressure separately and enter those values rather than using the Automatic Atmospheric Correction function.

•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 follo wing 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.

3. PREPARATION FOR SURVEYING

3.1 Centring and levelling of the instrument

[Setting up the instrument and the tripod]

Adjust the tripod legs so that a height suitable for observation is obtained when the instrument is set on the tripod.

Hang the plumb bob on the hook of the tripod, and coarse centre over the station on the ground. At this time, set the tripod and fix the metal shoes firmly into the ground so that the tripod head is as levelled as possible. If the tripod head is mis-leveled by the action of fixing the metal shoes into the ground, correct the level by extending or retracting each leg of the tripod.

3.2 Optical plummet

Look through the optical plummet eyepiece, and rotate the eyepiece knob until the centre mark can be seen clearly.

Rotate the focusing knob of the optical plummet and adjust the focus on the ground mark. Loosen the centring clamp screw and push the upper plate by finger and stay the centre mark on the ground mark.

Tighten the centring clamp screw.

Loosen the horizontal clamp screw and rotate the instrument every 90° and confirm the Circular vial is centred correctly. If the bubble is not centred, it can be properly set using the levelling screws.

18

3.3 Levelling with circular vial

Tripod is adjusted according to the following points by extending or contracting the legs so that the bubble of the Circular vial goes to the centre of the circle.

•Shorten the leg at the side of the bubble or extend the leg opposite of the bubble to position the bubble in the centre of the vial circle.

•All three legs are extended or contracted until the bubble is in the centre.

During this process, the foot is not placed on the tripod leg point and the position of the tripod points do not change.

3.4 Levelling with the plate vial

-(A) Align the plate vial in parallel with a line joining any two of the levelling screws. Then, adjust the two screws to centre the bubble in the plate vial.

-Turn two levelling screws in an opposite direction mutually in a way that the bubble moves from the side of the plate vial to the centre.

-(B) Rotate the total station 90°.

-Use the remaining screw to centre the bubble in the plate vial.

-Rotate the instrument by 90° and 180° and confirm the position of the bubble in the plate vial. At this time, it is not necessary to adjust it if the bubble of the plate vial is in the vicinity of the centre.

3.5 Eyepiece adjustment

[Eyepiece adjustment]

The eyepiece adjustment is performed before target sighting. Remove the telescope lens cap.

Point the telescope at a bright object, and rotate the eyepiece ring full counterclockwise. Look through the eyepiece, and rotate the eyepiece ring clockwise until the reticle appears at its maximum sharpness.

• When looking into the eyepiece, avoid an intense look to prevent parallax and eye fatigue.

19

•When it is hard to see the reticle due to poor brightness, press + to access

the RETICLE INTENSITY ADJ. screen. Use the left and right arrow to adjust the reticle intensity.

3.6 Target sighting

Loosen the telescope clamp and horizontal clamp screws. Point the telescope at the target using a collimator. Tighten the above two screws.

Adjust the eyepiece.

Look through the telescope and then rotate the focusing ring and stop it where the target can be seen clearly and the target image does not move in relation to reticle even if your eye is vertically and horizontally moved.

Align the reticle accurately on the target using telescope and horizontal tangent screws.

•Rotating the focusing ring “clockwise” makes it possible to focus on closer objects and “counterclockwise” will focus on further objects.

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 a 0 value for the Constant: Reflectorless (Non-Prism); N 0, Prism; P 0. Pressing changes the target mode.

•The target mode is changed sequentially as follows (On The reflectorless models) 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.

•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 the Reflectorless mode are determined in following conditions: a laser beam is emitted perpendicular to the white side of a Kodak Gray Card.

25

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 be impossible by dispersion or reduction of the laser beam when the beam comes into the target from a diagonal angle.

•There is a possibility that the instrument cannot calculate correctly when receiving reflected laser beams 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 cannot calculate correctly by collecting the reflected laser beam from a man or a car that comes and goes in front of the target. In the following environments, the distance might not be able to be measured:

There is a reflecting object (mirror, stainless board and white wall, etc.) in the direction of the target and under too strong sun light.

6.2 Distance measurement

The V-200 series have two distance measurement modes: primary MEAS and second MEAS.

Pressing the one time goes to MEAS and twice goes to second MEAS (continuous tracking measurement).

The number of shots can be defined. The default is “one time”.The measuring modes activated by the above operations can be also changed.

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 once to start measuring the distance. Once distance measurement has been started, the distance measurement mark remains displayed “( ( ( 0 ) ) )” . Upon reception of a reflected light from the target, the instrument beeps and displays the distance.

•If the instrument is in mode B, press the to switch to mode A and press .

•Pressing the 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 again terminates both distance measurement and blinking the “MEAS” text.

•Pressing 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 or or during distance measurement stops it.

•If the shot count for distance measurement has been set to 2 or more in “4 Shot Count", the distance is measured for the specified number of times to display the average value.

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

Collimate the telescope at a Target and press twice in succession to start measuring the distance, upon reception of reflected light from the target, the instrument beeps and displays the initial distance value. But it keeps on measuring and displaying the distance continuously while you move the telescope.

26

•If the instrument is in mode B, press to switch to mode A and press twice.

•Pressing 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 again, Distance measurement is completed and the “MEAS” text stops blinking.

•Pressing 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 or or during fast distance measurement stops it.
