Before using Gemred Smart Level, please read the manual carefully.
This user manual is intended as a guide to initial installation, integration and subs-equent use and notes of the Gemred Smart Level system.

Notes:

1. Without external interference, the data transmission distance can reach 10m;
2. Before using Smart Level, please use rust removing oil to remove debris and impurities on the machine surface and the measuring surface of the leveling, so as not to affect the validity of calibration and measurement accuracy by dust, grease, etc.
3. The Smart Level are calibrated at the factory. However, due to the change of exernal environment, it’s recommended to calibrate before use in order to ensure the measurement accuracy. For specific instructions Please refer to calibration part in the manual. (See page 14-15 for more details.)
