Operations

Measuring single distance

1. Aim the active laser at the target.
2. Press the 'ON/DIST' button. The distance is displayed.

Target Surfaces: Measuring errors can occur when measuring to colourless liquids, glass, styrofoam, or permeable surfaces, or when aiming at high gloss surfaces. Against dark surfaces, the measuring time increases.

Diagram Description: Diagram 1 shows the device ready. Diagram 2 shows the laser beam aimed at a target. Diagram 3 shows the measured distance (e.g., 8.532 m) displayed.

Permanent / Minimum-Maximum measuring

Hold the 'ON/DIST' button for 2 seconds to start this function. It is used to measure room diagonals (maximum values) or horizontal distances (minimum values). The minimum and maximum distances measured are displayed (min, max.). The last measured value is shown in the main line. Press the 'ON/DIST' button again to stop.

Diagram Description: Diagram 1 shows holding 'ON/DIST' for 2 seconds. Diagram 2 shows measurements being taken, displaying 'max' and 'min' values (e.g., 8.532 m). Diagram 3 shows stopping the measurement.

Add / Subtract

Perform a measurement. Then press the '+' button to add the next measurement or the '-' button to subtract it from the previous one. The result is shown in the main line. This process can be repeated for adding or subtracting areas or volumes. Press 'DIST' to show the final result.

Diagram Description: Diagram 1 shows an initial measurement (e.g., 7.332 m). Diagram 2 shows the '+' and '-' buttons. Diagram 3 shows a subsequent measurement added (e.g., 7.332 m + 5.515 m = 12.847 m).

Area

1. Press 'FUNC', then aim the laser at the first target point.
2. Aim the laser at the second target point.
3. Measure the height for the wall area.

The result is shown in the main line and the measured value above. The Painter function allows measuring and adding or subtracting wall lengths. Press 'FUNC' for 2 seconds to display the circumference.

Diagram Description: Diagram 1 shows pressing FUNC. Diagram 2 shows aiming at the first point. Diagram 3 shows aiming at the second point. Diagram 4 shows aiming at the second point for area calculation. Diagram 5 shows the calculated area (e.g., 24.352 m²). Diagram 6 shows pressing FUNC for 2 seconds to display circumference (e.g., 19.823 m).

Volume

1. Press 'FUNC' twice, then aim the laser at the first target point.
2. Aim the laser at the second target point.
3. Aim the laser at the third target point.

The circumference and wall area are displayed.

Diagram Description: Diagrams 1-7 illustrate aiming the laser at three different points to define the volume. Diagram 8 shows the displayed circumference and wall area (e.g., 80.208 m³, 208.70 m²).

Memory (last 10 results)

The last 10 measured values are displayed. Press the '+' or '-' buttons to navigate through the stored values.

Diagram Description: Diagram 1 shows the display indicating '1..10' and a stored value (e.g., 8.294 m). Diagram 2 shows navigating through the values using '+' and '-'.

Delete Memory

Press the Memory and Timer/Bluetooth® buttons simultaneously for 2 seconds to completely delete all stored memory.

Diagram Description: Shows the Memory and Timer/Bluetooth® buttons being pressed together for 2 seconds.

Timer (automatic release)

Press the Timer/Bluetooth® button for 2 seconds to set the delay for automatic release. The standard setting is 5 seconds, with a maximum of 60 seconds. Once the key is released, the laser activates, and the remaining seconds are displayed in a countdown before the measurement is taken. This is recommended for precise aiming, especially at long distances, to avoid device shake.

Diagram Description: Diagram 1 shows pressing the Timer/Bluetooth® button for 2 seconds, with '5' displayed. Diagram 2 shows the countdown '1...60' indicating the delay setting.

Pythagoras (2-point)

1. Press 'FUNC' three times (3x).
2. Aim the laser at the upper point.
3. Aim the laser at a rectangular point.
4. Aim the laser at the lower point.

The result (distance) is shown in the main line and the measured distance above. Pressing the measuring key for 2 seconds activates automatic Minimum or Maximum measurement.

Diagram Description: Diagrams 1-5 illustrate the process of aiming at three points to calculate a distance using the Pythagorean theorem. Diagram 5 shows the result (e.g., 8.294 m).

Pythagoras (3-point)

1. Press 'FUNC' four times (4x).
2. Aim the laser at the upper point.
3. Aim the laser at a rectangular point.
4. Aim the laser at the lower point.

The result is shown in the main line and the measured distance above. Pressing the measuring key for 2 seconds activates automatic Minimum or Maximum measurement.

Diagram Description: Diagrams 1-7 illustrate the process of aiming at three points to calculate a distance using the Pythagorean theorem. Diagram 7 shows the result (e.g., 8.294 m).

Stake out

1. Set a reference distance (e.g., 1.000 m).
2. Adjust the value if necessary using '+' and '-'.
3. Approve the value and start measurement.
4. Move the device slowly along the stake-out line. The distance to the next stake-out point is displayed.

The instrument starts to beep. The function can be stopped by pressing the 'CLEAR/OFF' button. If approaching a stake-out point to less than 0.1 m, a specific indication is shown. For example, '0.240 m is missing up to next 0.625 m distance'.

Diagram Description: Diagrams 1-5 illustrate the stake-out process, showing setting distances, moving along a line, and displaying remaining distances to target points.

Bluetooth® Smart
