6. First use
Before using the device, you need to stick the laser warning (included in the
package) on the device:
•
Refer to the safety instructions above before using the device.
•
Make sure the device does not contain any batteries.
•
The sticker is available in various languages. Put the sticker in your
language on the device.
•
When done, insert batteries (see section Battery below).
7. Measuring conditions
Measuring range
•
The measuring range is limited to 50m.
•
In dark environments or at night this range may increase.
•
In very light environments or when a surface has very poor reflective
properties, use a target plate.
Target surfaces
•
Measuring errors will occur when pointing at colourless liquids (e.g.
water) or glass, Styrofoam or similar semi-transparent surfaces.
•
Aiming at very shiny objects will deflect the laser beam which will lead
to errors.
•
Measuring towards non-reflective dark surfaces may increase the
measuring time.
•
Do not aim the meter directly into the sun or other bright light source.
8. General functions
Refer to the illustrations on pages 2 and 3 of this manual.
•
Make sure batteries are present inside the device (see section Battery
below).
