integrated circuit control board distance measuring head, using Androidid system,
with measuring software, it can display the measurement results of horizontal angle,
vertical angle, slope distance and flat distance, height difference, coordinates, etc. at
the same time, and it can measure angle and slope in many modes.
Prism-free rangefinding is even designed for users of engineering projects,
especially suitable for various construction fields. It can be widely used for three-
dimensional coordinates of buildings, position determination, overhang height
measurement, plumbness determination, pipeline positioning, section measurement,
etc. It is also suitable for triangulation control measurement, topographic
measurement, cadastral and property measurement, etc.
Cautions
1, daylight measurement should be avoided when the objective lens is aimed
directly at the sun. It is recommended to use a solar filter to diminish this effect.
2、Avoid storing the instrument at high and low temperatures and using the

Total Station ZTS-720 series instruction manual
4
instrument when there is a sudden change in temperature.
3、When the instrument is not in use, it should be put into a box, placed in a
ventilated and dry place, and pay attention to shock-proof, dust-proof and moisture-
proof.
4、If the temperature at the working place of the instrument is too different from
the temperature at the storage place, the instrument should be left in the box first
until it adapts to the ambient temperature and then take out the instrument for use to
obtain good accuracy.
5、If the instrument is not used for a long time, the battery should be removed
and stored separately. And the battery should be charged once a month to extend
the life of the battery.
6、The instrument should be packed in a box when transporting, and be careful
during transportation to avoid extrusion, collision and violent vibration. It is better to
use soft cushion around the box for long-distance transportation.
7、When setting up the instrument, use high-quality wooden stand as far as
possible to ensure the stability of the measurement to improve the accuracy of the
measurement.
8, in order to improve the accuracy of prism-free measurement, please be sure to
keep the object lens clean. Exposed optics need to be cleaned, the application of
degreasing cotton or lens paper gently wipe clean, do not use other items to wipe.
9、After using the instrument, use a lint cloth or brush to remove the dust on the
surface of the instrument. After the instrument is wet by the rain, do not power on,
should be clean and soft cloth dry and put in a ventilated place for a period of time,
so that the instrument fully dry before use or box.
10, before the operation should be carefully and thoroughly check the instrument,
to determine the instrument indicators, functions, power, initial settings and correction
parameters are in line with the requirements before the operation.
11、If the instrument function is found to be abnormal, non-professional
maintenance personnel should not disassemble the instrument without permission to
avoid unnecessary damage.

Security Guide
When using prism-free laser distance measurement, it is important to pay
attention to the following safety matters.
Warning.
The total station is equipped with laser class 3R/IIIa rangefinder.
This product is a Class 3R laser product, according to the following standards.
IEC 60825-1:2001 "Radiation safety of laser products".
For Class 3R/IIIa laser products, the emission limit at wavelengths of 400nm-
700nm can be achieved within five times that of Class 2/II.
Warning.
Continuous direct vision of the laser beam is hazardous.
Prevention.
Do not stare at the laser beam with your eyes or point the laser beam at others.
The reflected beam is a necessary measurement signal for the instrument.
Warning.
When a laser beam is directed at, for example, a prism, a flat mirror, a metal
surface, or a window, direct viewing of the reflected light with the eye can be
dangerous.
Prevention.
Do not stare at the laser reflection. Do not look next to the laser light path or prism
when the laser switch is on (ranging mode). Only look through the telescope of the

Total Station ZTS-720 series instruction manual
6
total station to illuminate the prism.
Warning.
Improper use of Class 3R laser equipment can be dangerous.
Prevention.
To avoid causing injury and to allow each user to take practical safety precautions,
control must be done within the distance of possible hazards (according to the
standard IEC60825-1:2001).
The following is an explanation of the main parts of the criteria.
Class 3R laser products for outdoor and construction site use (prism-free
measurement)
a Only persons who have received the relevant training and certification may
install, commission and operate such laser equipment.
b Set up the corresponding laser warning signs within the use area.
c To prevent anyone from looking directly into the laser beam with their eyes or
using optical instruments to view the laser beam.
d To prevent laser damage to people, the laser beam should be blocked at the
end of the working route. The laser beam must be terminated when there is human
activity within the restricted area (harmful distance*) through which the laser beam
passes.
e The path of the laser beam must be set above or below the human line of sight.
f laser products when not in use, properly stored for safekeeping, not certified
people should not use.
g To prevent the laser beam from unintentionally irradiating such as flat mirrors,
metal surfaces, windows, etc. Be especially careful of surfaces such as flat mirrors
and concave mirrors.
*The harmful distance is the maximum distance from the start of the laser
beam to the point where the laser beam weakens to the point where it will not cause
harm to a person. For built-in rangefinder products with Class 3R/IIIa lasers, the
harmful distance is 1000m (3300ft), beyond which the laser intensity is reduced to
Class 1 (no harm to the eye from visualizing the beam).
