Topcon releases the DL-500 series Digital Levels Featuring ‘Wave-and-Read' Technology 

Topcon Europe Positioning announces the release of the new DL-500 series digital levels. The new Topcon DL-500 implements the world's first ‘Wave-and-Read' technology. "This feature provides an additional survey style option that allows a rod person to wave the staff back and forth, instead of keeping the staff plumb," said Ian Stilgoe, geomatics business manager of Topcon Europe Positioning.

The staff reading becomes the minimum when it stands vertically. The DL-500 tracks the waved staff and automatically reads the least value. "This technology allows for error-free readings, while eliminating eyestrain," said Stilgoe.

The DL-500 also incorporates the advanced Random-Bidirectional code (RAB code) for the staff and optimum digital processing algorithm for staff reading. "These technologies give the DL-500 an ability to provide exceptional measurement accuracy, stability and speed under a variety of environmental conditions," said Stilgoe. "Even when the staff surface is partially shaded, or in dim lighting conditions as low as 20 lux, one single button triggers measurement and the DL-500 instantly records reliable results."

The DL-500 automatically recognizes the staff directions, either upright or inverted. "eliminating manual errors when surveying with normal and inverted readings." said Stilgoe.

Two models are available in different height measurement accuracy

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

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

DL-500 features include

? Reliable pendulum compensator with magnetic damping system

? 2,000 points internal memory

? Onboard measurement programs such as elevation, height difference, ceiling height, cut/fill and stakeout of horizontal distance
