*1 Auto-Tracking function can be added by upgrading.

*2 Average conditions: Slight haze, visibility about 20km (12 miles), sunny periods, weak scintillation.

*3 Figures when both the elevation and depression angles of the laser beam are within 15º and the instrument is facing the ATP1/ATP1S 360º prism

*4 When using a reflective sheet for Auto Pointing, the size of sheet (10 to 90 mm) must be selected to correspond to the distance being measured. Use smaller reflective sheets for shorter distances. Figures when the Auto Pointing beam strikes within 15° of the reflective sheet target.

*5 IEC60825-1:Ed.3.0:2014 / FDA CDRH 21 CFR Part 1040.10 and 11

*6 Average conditions: Slight haze, visibility about 20km (12 miles), sunny periods, weak scintillation.

*7 With Kodak Gray Card White Side (90% reflective). When brightness on measured surface is 30,000 lx. or less. Reflectorless range/accuracy may vary according to measuring objects, observation situations and environmental conditions.

*8 Good conditions: No haze, visibility about 40km (25miles), overcast, no scintillation.

*9 When the measuring beam's incidence angle is within 30º in relation to the reflective sheet target.

*10 Face the prism toward the instrument during the measurement with the distance at 10m or less.

*12 Measuring range:0.66 to 200m

*13 Fastest time under good conditions, no compensation, EDM ALC at appropriate setting, slope distance.

*14 Usage approval of Bluetooth wireless technology varies according to country. Please consult your local office or representative in advance. No obstacles, few vehicles or sources of radio emissions/interference in the near vicinity of the instrument, no rain.

*15 The laser-pointer and the guide light do not work simultaneously.

*16 Figures will change depensing on the operating environment including temperatures and observation conditions.
