Cause
7. Measuring Condition
7.1. Measuring Range
• The range is limited as per Technical Specifications.
• 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.
7.2. Target Surfaces
• Measuring errors can occur when measuring toward colorless liquids
(e.g. water) or dust free glass, styrofoam or similar semi-permeable
surfaces.
• Aiming at high gloss surfaces may deflect the laser beam and lead to
measurement errors.
• Against non-reflective and dark surfaces the measuring time may
increase.
7.3. 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.
