USAGE PRECAUTIONS
Surveying instruments are high-precision instruments. In
order to assure that the Electronic Total Station W-1500N 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 special solar
filter designed for this product to the objective lens.
[Laser beam]
E D M axis
The W-1500N series EDM is the red visible
laser beam and the beam diameter is very small. The beam is emitted from the
objective center and the base plate center hole. The EDM axis is designed to
coincide with the telescope sight axis but both axes may not sometimes coincide
slightly according to the intense temperature change and 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.
Reflector less and reflector sheet
●
Reflectorless:
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 following in case of distance measurement
by Reflectorless.
In a situation
resulting in low accuracy, perform the distance measurement by Reflector sheet
or Prism.
● There 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.
● There 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.
● There
is a possibility that synthesized values are calculated and the distance may become
longer or shorter than the actual one when the operator measure 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.
● 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 measurement 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
● Never use any battery charger other
than the BC05 battery charger as this may result in damage to 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 estimate of remaining battery power and is not completely
accurate. Replace the battery quickly when it is about to run down as the time
a battery lasts on one charge differs depending on conditions of ambient
temperature, and the measurement mode of the instrument.
●
Confirm the
battery level remaining before operating.
● When the remaining battery power becomes low, a message to
alert battery run-out starts coming up. When the message appears, replace the battery to a
fully charged one immediately. Running out of battery in middle of use may
result in loss of data.
L.D POINT, laser pointer
When
you make a correct direction using the “LD POINT”, aim the laser beam at the
wall and mark the center and then confirm the discrepancy between the reticle
center and the marked point beforehand.
Interface
Do not insert or remove USB Connector outdoors.
Be careful not to let dust, mud, sand, water, harmful gas or
salty steam enter the card slot or USB connector port.
Be sure to turn the instrument’s power off before inserting
or removing the USB Connector.
Touch panel
Use
the Stylus pen when you touch the panel for operation of software.
Do
not touch the panel with any things such as fingertips or pen point as this may
scratch and damage the screen.
