Measuring conditions
Measuring range
The Disty40 is limited to 40m, the Disty80 to 80m. 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.
Target surfaces
Measuring errors can occur when measuring toward colourless liquids (e.g. water) or dust free glass, Styrofoam or similar semi-
perme-able surfaces. Aiming at high gloss surfaces may deflect the laser beam and lead to measurement errors. Against non-re-
flective and dark surfaces the measuring time may increase.
Care
Do not immerse the instrument in water. Wipe off dirt with a damp, soft cloth. Do not use aggresive cleaning agents or solutions.
Handle the instrument as you would a telescope or camera.
