You can select the angle display unit that bests suits you. Horizontal angle is switchable between clockwise and counter-clockwise, and angle Hold and 0-set functions are also provided. Vertical angle can be set to Zenith=0, Horizontal=0, Horizontal=0±, or % of slope.
Sokkia's market proven advanced absolute encoders, which utilise RAB (RAndom BI-directional) code and digital sampling technology, further enhance the reliability of angle measurement. DT210 guarantees 2" accuracy, DT510/510A ensure 5" accuracy and DT610-7" for both horizontal and vertical angles.
With Sokkia's new algorithm in operating absolute encoders, power consumption has been dramatically reduced. Power by 2 standard LR14/C alkaline batteries, the DT210 and DT510 will operate for 75 hours, while the DT510A and DT610 will work for and astonishing 110 hours
you can start taking measurements as soon as you turn ion the power, thanks to the absolute encoders. Moreover, azimuth is kept when restarting the instruments after turning off the power.
The DT210/DT510 automatically compensate both Vertical and Horizontal angles by monitoring the tilt of the instrument in X&Y two directions.
Once the zero (0) horizontal angle direction is determined, all models emit audible tones for each of the four right-angle directions. Specifically, it sounds two different tones within ±15° of 90° and stops beeping when it comes within ±1°.
