Instrument Set-up

Overview

The safety instructions and user manual must be read and understood by all users before operating the product.

Display

The display shows measurement readings, units, battery status, and icons for measurement modes (Area, Volume, Pythagoras).

Key display elements include:

• Measuring Reference indicator
• Area / Volume / Pythagoras mode indicators
• Main measurement line
• Units indicator
• Battery level indicator

Battery Charging

Charge the device when the battery symbol is empty. The device uses a Type-C USB port for charging.

Operations

Switching ON/OFF

Press the [ON/Measure] button to turn the device ON. The device will automatically switch OFF after 120 seconds of inactivity to save power.

[Illustration: Device showing ON state with laser active, and OFF state after 5 seconds.]

Measuring Single Distance

1. Press the [FUNC] button to activate the laser.
2. Aim the active laser beam at the target surface.
3. Press the [FUNC] button again to take the measurement. The distance is displayed.

Note on Target Surfaces: Measuring errors can occur with colourless liquids, glass, styrofoam, or semi-permeable surfaces. Aiming at highly reflective surfaces or very dark surfaces may increase measuring time.

[Illustration: Steps for measuring single distance.]

Continuous Measuring

1. Press and hold the [FUNC] button for 3 seconds to enter continuous measuring mode.
2. Aim the active laser beam at the target surface and move the device slowly. The distance is continuously updated on the display.
3. Press the [FUNC] button to stop measuring.

Note on Target Surfaces: Similar to single distance measurement, certain surfaces may cause errors or longer measuring times.

[Illustration: Steps for continuous measuring.]

Advanced Functions

Unit Setting

• 0.000 m
• 0.00 ft
• 0 1/16 in
• 0'00'' 1/16

[Illustration: Device showing unit selection.]

Measurement Reference Changing

The device has two measurement reference points:

1. Default: Measurements are taken from the bottom edge of the device.
2. Press the [UNITS] button to change the reference to the top edge of the device for measurement.

1. Press the [FUNC] button to select Volume mode (indicated by '2x').
2. Aim the laser at the first corner of the volume (e.g., bottom front left).
3. Press the [FUNC] button.
4. Aim the laser at the second corner (e.g., bottom front right).
5. Press the [FUNC] button.
6. Aim the laser at the third corner (e.g., top front left).
7. Press the [FUNC] button. The calculated volume is displayed (e.g., 100.182 m³).

Pythagoras (2-point)

Calculates an indirect distance using two measurements and the Pythagorean theorem.

1. Press the [FUNC] button to select Pythagoras (2-point) mode (indicated by '3x').
2. Aim the laser at the first target point.
3. Press the [FUNC] button.
4. Aim the laser at the second target point, ensuring the laser beam is perpendicular to the measuring surface.
5. Press the [FUNC] button. The indirect distance is displayed (e.g., 3.907 m).

[Illustration: Steps for 2-point Pythagoras measurement.]

Pythagoras (3-point)

Calculates an indirect distance using three measurements and the Pythagorean theorem.

1. Press the [FUNC] button to select Pythagoras (3-point) mode (indicated by '4x').
2. Aim the laser at the first target point.
3. Press the [FUNC] button.
4. Aim the laser at the second target point, ensuring the laser beam is perpendicular to the measuring surface.
5. Press the [FUNC] button.
6. Aim the laser at the third target point.
7. Press the [FUNC] button. The indirect distance is displayed (e.g., 7.527 m).

Technical Data

General

* The typical measurement uncertainty of ±3 mm is valid for measurements on white, diffusive, reflective targets up to 10m at low ambient light and moderate temperatures. For distances greater than 10 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 ±6mm for distances below 10 m.
