How It Is Used
The jaws are closed and the display zeroed, then opened around the object, or the inside jaws or depth end used for bores and depths. The thumb roller gives fine movement and the locking screw holds a reading. As a school vernier caliper it suits physics practicals and workshop measurement alike.
