Digital Caliper

Instructions on use

• The Digital caliper is an extremely precise measuring instrument; the reading error is 1/100 mm = 0.01 mm.
• Loosen the lock screw, open the jaws and wipe clean using your finger. Close the jaws and verify the reading is zero, if not, press the red zero button.
• Close the jaws lightly on the object to be measured.
• If you are measuring something with a round cross section, make sure that the axis of the object is perpendicular to the caliper. This is necessary to ensure that you are measuring the full diameter and not merely a chord.
• Insure the readout is displaying milimeters not inches.
