6 MEASUREMENT INFORMATION

(HELIA RF & HELIA RF-M)

6.1 General measurement information

The following factors have an impact on the maximum
measurement range:
Colour of target
Surface
Angle to target
Size of object
Sunlight
Atmospheric conditions
Object structure

6.2 Single measurement

The aiming mark will appear when the measurement
button is pressed briefly. After the button is released, the
measured range is shown on the display.

6.3 Scan measurement

Scan Mode is used to continually measure the range
E
of moving targets. The instrument switches to Scan Mode
automatically if the measurement button is held down for
over 3 seconds. In Scan Mode, measurements will be
taken continually until the measurement button is released.

6.4 Angle measurement

In addition to the distance measurement, the angle of your
measuring position to any target can be shown on the
displays upper area.
20
Higher range Lower range
Light Dark
Shiny Matt
At right angle Acute
Large Small
Little A lot
(cloudy) (bright sunshine)
Clear Misty
Plane Variable
(e. g. wall) (e. g. bush, tree)

6.5 KAHLES EAC-function

Not only the distance measurement but also the KAHLES
EAC-function – Enhanced Angle Compensation which is
based on the classic Rifleman's Rule – can be shown.
While the Rifleman's rule only provides the slant range
based on pure mathematics the EAC-function also
considers the different ballistics and provides you a
more relevant basis. (For more information please visit

6.6 Long Range Function (HELIA RF)
In addition to the standard single measurement, the LR
function can be activated in the menu. It enables the
measurement of simple targets over very long distances
up to 4,500 meters. If the LR function is activated in the
menu, the HELIA RF transmits several pulses to determine
the distance. This is indicated in the display by the Aiming
mark flashing several times. The LR function can't be
combined with the angle indication or the EAC function
and the battery consumption is higher.

6.7 Temperature and airpressure display

By briefly pressing the mode button, on the display the
temperature appears for 3 seconds, then the air pressure
in hPA.
7 DISPL AY INTENSIT Y
(HELIA RF & HELIA RF-M)
There are 5 brightness levels to choose from. If the display
is activated a short pressing of the mode button changes
the display intensity.

8 MAINTENANCE AND CARE

We have designed all optical elements and surfaces to be
easy to care for. To guarantee the optical brilliance of
your binoculars over a long period of time, keep the lens
surfaces free of dirt, oil and grease. To clean the lenses,
