2. Aim laser at the first target point.
3. Press the [ON button].
4. Aim laser at the second target point (forming a 90° angle).
5. Press the [ON button].
6. Aim laser at the third target point (perpendicular to the measuring surface, forming a 90° angle).
7. Press the [ON button]. The result is shown in the main line and the measured distance above (e.g., 199'99" 7/16).

Pythagoras (5x): Calculates height based on three measurements:

1. Press the [Pythagoras icon].
2. Aim laser at the first target point.
3. Press the [ON button].
4. Aim laser at the second target point (forming a 90° angle).
5. Press the [ON button].
6. Aim laser at the third target point (perpendicular to the measuring surface, forming a 90° angle).
7. Press the [ON button]. The result is shown in the main line and the measured distance above (e.g., 199'99" 7/16).

Clear

Press the [Clear button] to undo the last action.

Bubble Vial

A built-in bubble vial enables a visual reference for horizontal alignment.

Memory

The last 30 measurements are automatically stored. Navigate up towards the memory using the [+] button. Navigate down towards the memory using the [-] button. Press the [Power button] to delete the memory.

Technical Data

General

*The typical measurement uncertainty of ± 3 mm is valid for measurements on white, diffusive, reflective targets up to 5 m at low ambient light and moderate temperatures. For distances greater than 5 m, the measurement uncertainty could increase additionally by 0.1 mm/m. In unfavourable conditions (such as bright sunlight, targets with poor reflectivity, or high or low temperatures), the measurement uncertainty could further increase up to ± 8 mm for distances below 5 m and additionally by roughly 0.15 mm/m for distances greater than 5 m.
