Technologies for Precision
The DL-501 series incorporates an array of advanced technologies to achieve the highest leveling accuracy in the industry.
• RAB-Code technology, superior optics, market-proven compensator and magnetic damping system ensure precise staff readings.
• Dual-axis compensator notifies instrument tilt, Remote Trigger prevents accidental jolts, and Auto Focus (DL-501 Advanced model) eliminates incomplete focusing. These unique technologies remove major error factors.
• Even in the dim light conditions, if the staff surface brightness is 20lx or more, the DL-501 series can read the staffs without compromising accuracy.
Technologies for Speed
Both models feature the measurement time of 2.5 seconds - the fastest in its class. The DL-501 Advanced model, equipped with Auto Focus and View Finder for quick
sighting, saves measurement time by up to 40% compared to manual focus digital levels.
Measurement Programs
Onboard program supports line leveling and data recording.
• Methods: BF, BFFB, BBFF, BFBF, aBF, aBFFB, aFBBF
• Up to two intermediate sights can be measured in each set.
• Adjustable tolerances and error calculation functions allow for on-site accuracy checks.
