Measuring Conditions

Measuring Range
The range is limited to 60 m (P 2801) or 80m (P 2802). At night or dusk and if the target is in shadows 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 colorless liquids (e.g. water) or dust free glass, Styrofoam or similar semipermeable surfaces. Aiming at high gloss surfaces may deflect the laser beam and lead to measurement error.
Against non-reflective 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 aggressive cleaning agents or solutions. Handle the instrument as you would a telescope or camera.

Troubleshooting
