Description
1. Angle measurement accuracy improve
- Vertical angle: integrated unitary axis, less components. Less offset tolerance.
- Angle reading: 4 detector technology, reduce disk offset angle and rit tolerance.
2. Distance measurement accuracy improve
- Optical path change: totally new 5 axis design, fully isolation emitting and reflect signal. Reduce optical Crosstalk.
- Circuit design change: 150MHZ ultra high measure frequency, improve measure tape accuracy, Development by self. Improve SNR (Signal noise rate)
3. Geometry accuracy improve
- Clear telescope and high accuracy tribrach system, make sure pointing accuracy.
4. Compensator accuracy improve
- Micro survey tile tolerance by CCD image to compensate.
5. UE (User experience) improvement
- 640*480 high resolution.3.5 inch display unit. Easy to read under sunshine.
- WIN CE 6.0 OS, blue tooth standard, WIFI, Bluetooth standard.
- Ultra measure speed. Fine0.3S, track 0.1s.
- A variety of data transfer options for diverse needs, eg. SD card, mini USB interface.
