Simple Button Operation!

After focusing on the staff, just press one button. The DL-500 reads height and distance, and stores data. Digital technology eliminates misreading and reduces operator’s eye fatigue.

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

DL-500 tracks the RAB Code staff waved back and forth, and automatically reads the correct height.
The staff reading becomes the minimum when it stands vertically. The DL-500 automatically finds the least value of staff readings.
This world’s first technology allows for error-free readings of waved staffs, while dramatically reducing operator’s eyestrain.

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

Measures Ceiling Height! Inverse Staff Reading

RAB Code staff can be read in inverse position. This feature dramatically facilitates height measurement of ceilings, tree branches, road signs, bridges, tunnel crowns, and other structures.

Practical measurement Programs! No Need for Calculators

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

Calculates elevation of foresight (FS) with reference to the backsight (BS) elevation.
Elevation of turning point (TP) is used for a new backsight, allowing for consecutive leveling.
Cut and Fill
Cut and fill stakeout facilitates slope works. Measurement can be taken with 0.1mm or 1mm (0.001ft. or 0.01ft.) resolutions.
Height Difference
Automatically displays the height difference between backsight (BS) and foresight (FS) in 0.1/1mm (0.001/0.01ft.) unit.
Ceiling Height
Two measurements provide a ceiling height; one with a staff placed on the ground, the other with an inverted staff put onto the ceiling. Elevation of ceiling can also be calculated with reference to the benchmark elevation.

Internal Memory and Easy Data Transfer!

Internal Memory and Easy Data Transfer!
DL-500 stores up to 2,000 measurement data. The “DL-500 TOOL” software transfers data to a computer in CSV format.
