Measurement Reference
The system default measurements start from the bottom of the device as the reference point.
To change the reference point:
- Press the [Units Button] to change the reference to the extension bar point for measurement.
- Press the [Units Button] again to change the reference to the top of the device for measurement.
Functions
Measuring Single Distance
1. Aim the active laser at the target.
2. Press the [Laser On Button].
3. The measured distance (e.g., 39'99" 7/16) is displayed.
Target surfaces: Measuring errors can occur when measuring to colourless liquids, glass, styrofoam, or semi-permeable surfaces, or when aiming at high gloss surfaces. Against dark surfaces, the measuring time increases.
Continuous Measuring
1. Press and hold the [Laser On Button] for 3 seconds.
2. Aim the active laser at the target.
3. The last value measured is continuously displayed.
4. Press the [Laser On Button] to stop continuous measuring.
Area Measurement
1. Press the [Area/Volume/Pythagoras Button] once (1x).
2. Aim the laser at the first target point.
3. Aim the laser at the second target point.
4. The result (e.g., 29.99 ft²) is shown in the main line and the measured distance above.
Volume Measurement
1. Press the [Area/Volume/Pythagoras Button] twice (2x).
2. Aim the laser at the first target point.
3. Aim the laser at the second target point.
4. Aim the laser at the third target point.
5. The result (e.g., 29.99 ft³) is shown in the main line and the measured distance above.
Pythagoras (2-point)
1. Press the [Area/Volume/Pythagoras Button] three times (3x).
2. Aim the laser at the first target point.
3. Aim the laser at the second target point.
4. The result (e.g., 39'99" 7/16) is shown in the main line and the measured distance above.
Pythagoras (3-point)
1. Press the [Area/Volume/Pythagoras Button] four times (4x).
2. Aim the laser at the first target point.
3. Aim the laser at the second target point (perpendicular to the measuring surface).
4. Aim the laser at the third target point.
5. The result (e.g., 39'99" 7/16) is shown in the main line and the measured distance above.

* 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.
Error, Faults & Troubleshooting
| Issue | Cause | Action |
|---|---|---|
| Failure to switch on | Hardware protection after shocking | Restart the device |
| Low battery | Recharge the device | |
| All dashes shows on display | Insufficient On/Measure/Units button press | Press the On/Measure/Units button firmly |
| Beam is moved too fast | Move the measuring tool slowly | |
| The object is out of rated range | Measure within rated range | |
| Received signal too weak / Measuring time too long | Change target surface (e.g. white paper) | |
| Received signal too strong (target is too reflective) | Change target surface (e.g. white paper) | |
| Ambient light is too strong | Shadow target area |
