Horizontal ruler 8 length can adjust.
Experimental technique:
1. probe into gravity direction experiment
A. demonstration device is placed in horizontal table top, by water tank and support installing on the supporting plate, in water tank, fills the water of about 2/3 volume.Now pointer and vertical scale are in same direction, vertical with the water surface in water tank with horizontal ruler.
B. supporting surface is slowly lifted suitable angle, pull carriage back up pad to be propped.Now weight is vertical with the water surface in tank, but forms an angle with scale.
2. check plane whether level
Support is taken off from back up pad, scale is moved on to support central authorities, then support is lain in plane to be measured, if pointer and horizontal ruler central authorities groove on illustrated planar level.
3. check metope whether vertical
Support is taken off from back up pad, scale is moved on to above support, then support is close on metope to be measured, if pointer and vertical scale central authorities groove illustrate that metope is vertical.
