Electronic Digital Level

 

World’s First “Wave-and-Read” Technology

 

Topcon DL-500 series digital levels maximize work efficiency and minimize human error, providing consistent measurement precision and speed, regardless of operator skill.

 

Incorporating cutting-edge Random-Bidirectional (RAB) coding technology, an optimized digital processing algorithm, the DL-500 provides exceptional measurement accuracy, stability and speed, under a variety of environmental conditions. Even when the staff surface is partially shaded, or in dim lighting conditions as low as 20 lux, a single button triggers measurement and the DL-500 instantly provides reliable results.

 

The world’s first “Wave-and-Read” technology provides an additional survey style option that allows a rod operator to wave the staff forward and back, instead of keeping the staff plumb. This simpler method is faster, easier, minimizes the fatigue and is just as accurate.

 

Pre-installed measurement programs assist various leveling tasks and accompanied calculations. Internal memory stores field data, and can be directly transferred to your computer via serial cable, eliminating human error.

 

 

High Accuracy! 0.6mm/0.8mm

Two models are available for different accuracy requirements.

 

DL-502: 0.6mm (Invar staff), 1.0mm (fiberglass staff)

 

DL-503: 0.8mm (Invar staff), 1.5mm (fiberglass staff)

 

 

 

Maximum Reliability! Field-proven Compensator

 

Incorporating a field-proven pendulum compensator with magnetic damping system, the DL-500 provides the stability you need when working on busy roads or bridges subject to vibrations.

 

 

 

Measures Ceiling Height! Inverse Staff Reading

 

The DL-500 can read the RAB-code staff in the inverted position. This feature dramatically facilitates height measurement of ceilings,

 

tree branches, road signs, bridges, tunnel crowns, and other structures.

 

 

The World’s First “Wave-and-Read” Technology

 

The DL-500 tracks the RAB-code staff when waved forward and back, and automatically reads the correct height. The reading is at the minimum when the staff stands vertically, and the DL-500 automatically finds the least value of staff readings. This technology eliminates the need for keeping a staff plumb, further enhancing work efficiency and measurement accuracy.

 

Practical Measurement Programs! No Need for Calculators

Onboard programs support various measurement routines such as elevation, height difference, ceiling height, as well as cut/fill and stakeout in horizontal distance.

 

Internal Memory and Easy Data Transfer!

 

DL-500 stores the data for up to 2,000 measurements. DL TOOL software transfers data to your computer in CSV format, via serial cable.
