* Measurement error could reacher +/- 2mm 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.
Measuring conditions - Measuring range
The range of 50m instrument is limited to 50m, At night or dusk and if the target
is in, shadow the measuring range without target plat is increased. Use a target
plate to decrease 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. wa-
ter) or dust free glass, styrofoam or similar semipermeable surface. Aiming at
high gloss surfaces may deflect the laser beam and lead to measurement errors.
Against nonreflective and dark surface the measuring time may increase.
Care
Do not immerse the instrument in water. Wipe off dirt with damp, soft cloth. Do
not use aggressive cleaning agents or solutions. Handle the instrument as a
camera or telescope.
