5. Betjeningsvejledning
5.1 Laser Measurement (DT11 & DT20)
The integrated laser rangefinder can measure distances up to 40 meters with a high accuracy of ±2mm.
- Sørg for, at enheden er tændt.
- Press the "Measure" button once to activate the laser. A red laser dot will appear from the device.
- Aim the laser dot precisely at your target point.
- Press the "Measure" button again to take a single measurement. The measured distance will be displayed on the screen.
- For continuous measurement, press and hold the "Measure" button. The display will update in real-time as you move the device, allowing you to find minimum or maximum distances.

5.2 Tape Measurement (DT11 & DT20)
The physical tape measure extends up to 5 meters (16 feet) and features a durable nylon coating for wear resistance.
- Træk forsigtigt målebåndet ud til den ønskede længde.
- The tape features a gate switch mechanism. Pressing this switch locks the tape securely in place, preventing accidental retraction and ensuring user safety by avoiding rebound.
- To retract the tape, release the gate switch, and the tape will smoothly retract into the device.
