Safety Regulations
Please read the safety regulations and
operation guide carefully before operating.
Please read all of the operational
guide and safety regulations in this
manual before operation . Improper
operations without complying with this
manual guided could cause damage to
the device, influence on measurement
result or bodily injury to the user.
The instrument is not allowed to
disassemble or repair in any ways. It is
forbidden to do any illegal modification
or performance change for laser emitter.

and stand by for measurement.
Under on state, long press key for 3
seconds to make the device off. The
instrument will be shut off without any
operation for 150 seconds.

Press key to enter into setting of
switching between front benchmark
and end benchmark . System usually
takes end benchmark as default.
Single Measurement:
Press key under measuring mode,
the laser is emitted to shoot measuring
location.
Re-press key for single measurement
of distance , then the measured results
displayed on main display.

Area measurement:
Press key and you will see ,on
the display screen, that is Rectangle
with one edge flashing. Complete the
following operations according to
screen tips: Press key to measure
the first edge(length). Press key to
measure the second edge(width) Area
will be calculated automatically by the
meter, and the results showed on main
display screen.
Continuous Measurement:
Long press key under measuring
mode to enter into continuous
measurement state, and maximum
and minimum measurement results in
the process of continuous measurement
will display on the screen.
The main display screen indicates the
very measured result, press key
to exit continuous measurement state.
Press key to remove previous
measured result and get ready for the
next measurement.
Volumetric Measurement:
Double press key and you will see ,
on the display screen, that is cube with
one edge flashing. Complete the
following operations according to tips:
Press key to measure the first edge
(length).
Pres key to measure the second
edge(width).
Press key to measure the third edge
(height).
Volume will be calculated automatically
by the meter, and the results showed on
main display screen.
Press key to remove previous
measured result and get ready for the
next measurement.

There are three kinds of pre-designed
measuring mode to get unilateral
distance of triangle by ways 66
of Pythagorean proposition. This is
convenient for users to do indirect
measuring in certain complex
environment. Press key to make

1) Press key and you will see on
the display screen, that is triangle with
hypotenuse flashing.
Press key to firstly measure the
length (a) of dotted line hypotenuse
according to screen prompt
Press key to measure the length(b)
of the dotted line right side Length (x)
of the solid line right side will be
calculated automatically by the meter.
2) Double press key and you will see
on the display screen, that is triangle
with vertical leg flashing
Press key to firstly measure the length
(a) of dotted line right side according to
screen prompt
Press key to measure the length (b) of
the other dotted line right side
Length(x) of the solid line hypotenuse
will be calculated automatically by
the meter.

Press key to firstly measure the
length (a) of dotted line hypotenuse
according to screen prompt
Press key to measure the length(b)
of dotted line hypotenuse (shown as
in the figure
Press key to measure the length(c)
of another dotted line hypotenuse
(shown as in the figure)
Length (x) of the solid line right side
will be calculated automatically by
the meter.
Under Pythagorean proposition
measurement mode, length of right side
must be shorter than hypotenuse length
so that instrument can make out
calculation, otherwise the instrument
will display error signal.

Under Pythagorean proposition mode,
to ensure the accuracy of measurement,
it must be measured from the same
starting point with a measuring order of
first hypotenuse, and then right side.

Browse Measurements
Press key to check stored
measurement data, Press key or
key to browse forward or backward.
Long press , key can remove all
stored records.
Store Measurements
Under measuring mode, as the exiting
data is effective, long press key for
3 seconds, the very measurement data
will be automatically stored into the
instrument memory stick.
SW-100 and SW-100 A respectively has
maximum storage volume of 30 units.
Press key, and "+"appears on main
measurement screen , then enter into
accumulated adding measurement
mode, accumulative value of previous
measured value and the very
measurement results will be displayed
on the screen.
Press key, and "-"appears on main
measurement screen, then enter into
accumulated subtracting measurement
mode, differences between previous
measured value and the very
measurement value will be displaye
on the screen.
Add And Subtract Measurement:
Single distance measurement can be
done through adding/subtracting to get

Note: There will be a bit of greater
differences of measurement results in
harsh environment, such as strong
sunlight, excessive temperature
fluctuations, weak reflective surface,
low battery. As to this, targe treflection
board as auxiliary will assist you to get
a better result.
Instrument maintenancetions:
• The meter should not be stored in high
temperature and strong humidity
environment for long-term; if not used
for long time, please take out the
battery and place the meter in the
allocated potable bag and store in
cool and dry place.
• Please keep the device surface
cleaning. Wet soft cloth is applied to
clean dust, but erosion liquid is never
allowed to use for the meter
maintenance. Laser output window
and its focus lens can be maintained
according to maintenance procedures
for optical device.
