GDS850 High precision handheld electronic level Product manual V1.9-20250918

Technical Highlights ❖ Capable of recording key measurement data; ❖ Customers can calibrate the zero point themselves; ❖ Dual strong magnetic measuring surfaces on the bottom left. The GDS850 is a level gauge developed by RUICOM Technology based on a high-precision tilt measurement platform. It uses a built-in MEMS sensor to sense the Earth's gravitational field, thereby obtaining the horizontal tilt angle of an object. Its built-in 32-bit microprocessor can perform high-resolution sampling of the weak current and tilt angle ratio signals from the front end, achieving an accuracy of 0.002° and...

Click the MODE button to switch the product unit mode. As shown in the figure, the unit modes are "degree" mode, "degree, minute, second" mode and "mm/m" mode in sequence; the three modes can be switched in a cycle. Product Maintenance- 1. The digital angle meter uses two AA batteries (2A). 2. If there is no digital display when the power switch is turned on, please check if the batteries have power or if they are installed incorrectly. 3. This instrument is highly reliable and can be used in vibrating environments, but please do not drop it from a height, as this will cause permanent damage....
