dual axis turntable test and calibrate for inertial device and sensors

I. Main uses and functions

The turntable is a table-type structure test equipment produced by our company, which can be used for the detection and test of inertial measurement unit, and can also be used for the calibration and measurement of two-dimensional rotation angle of other instruments.

The main functions are:

1. Accurate rotation angle of inner ring and outer ring and display angle;

2. Function of horizontal adjustment;

3. Align and aim at the installation position;

4. The scale ring on the mechanical table body realizes the preliminary angle indication;

5. The mechanical table body uses the operating hand wheel and handle to realize manual indexing;

6. The inner ring shaft and the outer ring shaft have mechanical locking function;

7. Digital display electric box has RS232 interface.
