3.4 Distance conditions:
- No display = standard condition;
- “RAIN” = refers to rainy conditions, measuring objects beyond 60m
- “REFL” refers to for foggy conditions
- “>150” indicates that there are interfering objects within 150m
3.5 The quality of the measurment. This is displayed via the text -
“QUALITY▼▼▼▼▼▼▼▼▼▼” - just under the field of vision. When there are six or more
“▼” symbols, this indicates that the return-wave is strong enough to measure and display
distance.
3.6 Laser emission: when emitting the laser, the “LASER” glitters.
3.7 When “BATT” is displayed, this indicates that the battery needs to be changed due to
low battery power.
4. Measuring Distance
4.1 Adjust the eyepiece degree of the telescope to make the object clear in the field of
vision.
4.2 Click the “trigger” button. The lens will display “+”, as a crosshair. Aim the device at
your desired object. Re-click the “trigger” button and keep pressing it for about three
seconds. It will display the distance of the object. The device will shut off
automatically if it is not used in fifteen seconds.
4.3 In order to ensure accuracy, keep pressing the “trigger” button for more than three
seconds until the distance of the object registers for the second time. Note: do not
press the button excessively.
4.4 Use the “mode” button. The use of each mode should be chosen in accordance with
the environment/conditions in which the measurements are being taken. When
switching the device on, the default mode will be the last mode chosen by the user.
4.5 If the distance unit needs to be switched, keep pressing “mode” for more than three
seconds.
4.6 Distance-measuring of the Rangefinder is affected by the characteristics of the
objects, the angle of the emitted light beam, the surface of object, and the visibility of
weather. Generally speaking, if the surface of the object is smooth, the light is bright,
the area is large, the light beam is vertical with the surface of the object and the day
is fine, the distance tends to measure longer. In the opposite conditions, the distance
will generally be recorded as shorter.
