In 2009, SOUTH introduced a new digital level DL200 series， with the latest international level digital signal processor and the technology of bar code identification and recovery, which realized the digital processing. The features as follows:

1. Error-free reading. There will be no misreading, misrecording and human error. Users only need to aim and focus the bar code staff, press the measurement button when reading is clear, then the data will be on the screen. The data can also be stored in the memory or SD card (SD card only for 201 series).

2. High accuracy. During measurement, the elevation and range are calculated from large amount of bar code divided images, which largely minimizes the errors by bar code division and improves the accuracy of measurement. Meanwhile, the repeat measuring mode can weaken the impact of the external conditions, so intensive training is not needed.
 
3. Rapidity. By eliminating the process of reading, recording, and calculating on site’, the DL series greatly shorten the measurement time.

4. High efficiency. Simply aiming, focusing plus pressing the button, the instrument can measure by itself, which largely reduce the work amount. At the same time, DL series can automatically record, check and process the observation data and even input these data into computer for post-processing, which enables the integration of indoor and outdoor works.

5. The I angle adjustment program allows users easily adjust I angle on sight.

6.Stylish exterior, integrated carrying handle, easy to carry outside.

7.Ultra-low power consumption, the maximum power consumption is only 0.7w and the lowest is only 0.26w when measuring, real energy-saving green product.

8.Highly streamlined circuit design, using the world’s most advanced digital signal processing technology, highly streamlined and integrated design, stability largely improved.
