construction • Powered by 2 standard LR14/C alkaline batteries, the DT210 and DT510 will operate for 75 hours, while the DT510A and DT610 will work for an astonishing 110 hours. • Sokkia’s market-proven absolute encoders, utilize which RAB (RAndom Bi-directional) code and digital sampling technology, further enhance the reliability of angle measurement. Electronic Digital Theodolites The DT210, DT510, DT510A, and DT610 feature ultra-low power consumption and Sokkia’s advanced absolute encoders. IP66-compliant bodies securely protect the instruments against dust and water. • Angle display units are selectable from 1”, 5”, 0.2mgon, 1mgon, 0.005mil, or 0.02mil (DT210, DT510, DT510A); or 5”, 10”, 1mgon, 2mgon, 0.02mil, or 0.05mil (DT610). • For increased convenience, once the zero (0) horizontal angle direction is determined, all models emit audible tones for each of the four right-angle directions. * 1 * 2 • Measurement data can be output via the RS-232C data port (DT210, DT510, DT510A). 1 • • The DT610 has a fi xed base. Shifting tribrach model is also available as a factory option (DT610S). * DT210 DT510 * 2 DT210 • DT510 • DT510A DT510 DT210, DT510, DT510A & DT610 SPECIFICATIONS DT210 DT510DT510ADT610Telescope Magnifi cation 30x 26x Display Resolutions 1”/5”, 0.2 / 1mg, 0.005 / 0.02mil, selectable 5”/10”, 1 / 2mg, 0.02 / 0.05mil Accuracy (ISO 12857-2 : 1997) 2” / 0.6mg 5” / 1.5mg 7” / 2.2mg Display LCD, 8 digits x 2 lines with backlight Display location On both faces On one face Compensator Dual-axis compenstor, working range 3’ (55mgon) n / a Dust and Water Protection IP66 (IEC60529) Weight w/handle 4.7kg 4.5kg 4.2kg Battery LR14/C batteries x 2 Continuous use with alkaline batteries Approx. 75 hours Approx. 110 hours 30
