Usage precautions

Surveying instruments are high-precision instruments.In order to assure that the Electronic
Total Station V-300 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-300 is a class-II Laser product.
( The reflectorless type is a Class IIIa (3R) laser product.)

[EDM axis]

The V-300 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 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.ver tical 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.

7

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.

[Storage and operating environment]

• To prevent making short-circuit when removing the battery and charger from the case and
storing them,apply elec trically 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.

• 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,batter y 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.

17

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.
