Remarks：Measurement could reach 10 m in good conditions ( good measurement
surface, room temperature ).Under adverse measuring conditions, such as the light is
too strong, the measured surface reflective weakly or the temperature difference is
too large, or the deviation over distance above 10m will increase on ±0.2
mm/m.
9. Measuring Conditions
9-1 Measuring Range
The range of this meter is limited to 30m, at night or dusk and if the target is
in shadow, the measuring range without target plate is increased. Use a target
plate to increase the measurement range during daylight or if the target has
poor reflection properties.
9-2 Target Surfaces
Measuring errors can occur when measuring toward colorless liquids (e.g.

13
water) or dust free glass, Styrofoam or semipermeable surfaces. Aiming at
high gloss surfaces may deflect the laser beam and lead to measurement
errors. For non-reflective and dark surfaces the measuring time may increase.
-if the equipment is used in a manner not specified by the manufacture, the
warranty will be invalid
Care
Do not immerse the instrument in water. Wipe off dirt with a damp, soft cloth.
Do not use aggressive cleaning agents or solutions. Handle the instrument as
you would a telescope or camera.
