Quick guide to Calipers

Terminology:

Before Use:

• Clean the jaws with a dry cloth and close the measuring faces.
• Hold it against a light source. No light should be seen between them.
• However, if some light is seen, it means the outside measuring faces have contamination or burrs as they will not close properly on their full length.
• Similar observation can be done for the inside measuring faces.
• For digital calipers, note that when the battery is newly inserted or replaced, a dash line will appear.
• Just close the measuring faces and hold the ORIGIN/PRESET button to perform a zero point setting.

During Use:

• Make sure to measure the object as close to the scale as possible and apply constant force when doing measurements. Make sure that the measuring faces are not tilted in any way.

After Use:

• Wipe the main scale with a clean cloth to remove any sweat or oil that may be present.
• The outside measuring jaws should be opened slightly with the locking screw untightened before storing in its proper case.
