*maximum deviation occurs under unfavourable conditions such as bright sunlight or when measuring to poorly reflecting or very rough surfaces. Measuring accuracy between 10 m and 30 m may deteriorate to approx. ± 0.025 mm/m, for distances above 30 m to ± 0.1 mm/m. In long range mode the maximum deviation from a distance of 30 m increases to +/- 0.15 mm/m.

**applies at room temperature. For the whole operating temperature range the maximum deviation increases by +/- 0.1°.

Measuring conditions

Measuring range

The range is limited to 200 m.

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.
