surfaces (mirrors, etc.).
The rangender is intended for professional use
only. Do not give the device to untrained persons.
Improper handling of the instrument may
damage the instrument or aect measurement
accuracy.
Do not disassemble or repair the device yourself,
do not try to modify its design. If you have technical
problems, please contact your dealer or service.

2. Installing and replacing batteries
Open the battery cover, insert two 1.5V AAA
batteries. Observe the polarity of the installation.
Then close the cover.
If you do not use the rangender for a long time,
remove the batteries to avoid battery leakage and
damage to the device.
3. Getting started
Turning on. To turn on, press button for
1second. The display backlight automatically turns
o after 15 seconds of inactivity of the device.
Measurements.When on, press button once to
turn on the laser. Press the same button again to take
the measurement. At the end of the measurement,
the laser will turn o automatically. Long press of
button will switch the device to continuous
distance measurement mode. Symbol on the
display shows the strength of the reected signal,
the fewer segments in this symbol - the weaker the
signal.
Change of measurement reference point. Long
(more than 2 seconds) pressing of button with
the device switched on switches the measurement
reference point. When the device is switched on, the
reference point is set by default - from the lower end
of the device, that is, the measurement result includes
the length of the device itself. When changing the
reference point to the front end of the instrument,
the result does not include the instrument length.

Turning o. Press button for 1 second to turn
o the EDM. The device turns o automatically after
45 seconds of inactivity.
Instrument settings. Long (about 5 seconds)
pressing of button with the device turned o
starts the setup mode (see the gure below). Pressing
and holding button again for 1 second switches
the settings of dierent functions of the device.
1. In this mode, the measurement value can be
corrected within ±7 mm. A short press on button
adjusts the value.

Select the required unit of measure by short pressing
the button .

Area measurement.
Turn on the device, briey press button , the
area measurement mode is started. The screen will
display – a rectangle with a ashing side. Select
the point of the aiming shape, press , to measure
the distance. The other side of the rectangle icon
will start ashing. Measure the second distance,
the device will calculate the area automatically. The

8 9
lengths of the sides will be reected on the sub
screen, the resulting area value - below on the main
screen.
Volume measurement.
Press button briey until icon is displayed
on the screen. The device has entered the volume
measurement mode. Take three measurements
(length, width, height), the device will automatically
calculate the volume - similar to the calculation of
the area from the previous paragraph of this manual.
Pythagoras measurements.
Press button briey until icon is displayed
on the screen. The device can carry out three types of
distance calculations according to the equation from
the Pythagorean theorem, the type of calculation
is indicated on the display: , or . Select
the desired mode by short pressing the button,
measure the lengths of two segments, the device will
automatically calculate the third value - similar to the
calculations in the previous paragraphs.
Attention: when taking measurements according
to Pythagoras, it must be remembered that in a
right-angled triangle, the leg is always shorter than
the hypotenuse. If the values are entered incorrectly,
the display will show the error message "D. E".

Under good measurement conditions (the surface
reects light well, measurements are taken indoors),
the range can reach 40 m.
In poor conditions (too bright light, high
temperature, the surface does not reect light well),
the measurement error can be up to ± 0.25 mm/m.
Use a laser target to increase the measuring
distance in bright sunlight or if the surface to be
measured reects light poorly.
