The divider calliper is used for transferring measurements, dividing distances, and marking off equal segments.
Make sure the calliper is perpendicular to the object being measured and that the points are in full contact with the surface. Tighten the adjustment screw gently until the points touch the surface, then read the measurement from a ruler or tape.
Dry them immediately with a clean cloth. Apply a thin coat of oil to prevent rust.
No, this set is designed for measuring inside and outside diameters only.
Store them in a dry place, ideally in a toolbox or a protective case to prevent damage and corrosion.
The self-seated washer ensures quick and accurate measurements by providing a stable and reliable point of contact for the adjustment screw.
Check the calliper points for any damage or wear. Ensure the adjustment screw is properly tightened without being overtightened. Recalibrate if needed using a known standard.
Apply a small amount of light machine oil to the screw and threads. Clean any debris that may be obstructing the mechanism.
