简介
Follow this guide to learn how to use digital calipers to take measurements.
Screw and part dimensions are vital for organizing your electronics repairs, ensuring each screw is put back in its correct place during reassembly—saving you time and frustration!
Calipers precisely measure lengths, thicknesses, and diameters using two sets of jaws. The small inside jaws measure internal diameters, while the large outside jaws measure external diameters, lengths, and widths. A probe on the opposite end measures depth. Digital calipers have the ability to zero and often support more than one unit of measurement.

你所需要的
-
-
An on/off button
-
A zero button that sets the current reading to zero
-
A units button that switches between imperial and metric measurements, commonly written as mm/inch
-
A thumb screw that opens and closes the jaws
-
A locking screw that holds the jaws in place to keep the current measurement
-
-
-
Before using your calipers, clean the inside of the jaws with a fresh cloth or rag to make sure there's no dirt or grime that could affect measurements.
-
-
-
To open or close the jaws, press down on the thumb screw and gently roll it in the direction you want the jaw to move.
-
-
-
-
Gently close the jaws.
-
Press the zero button to set the current measurement to zero.
-
-
-
Open the jaws wide enough for the object being measured to comfortably fit between them.
-
Gradually close the jaws until both sides touch the object. Don’t push too hard, yet firm enough to make sure both jaws sit flat against the object.
-
Check that your object isn’t crooked when you take your measurement.
-
Read the measurement.
-
Take the measurement a few times and make sure it's the same—or very close—each time. If you get inconsistent readings, zero the calipers and try again.
-
Zero the calipers before making another measurement.
-
-
-
Close the jaws until you can comfortably fit them inside the object.
-
Gradually open the jaws until both sides touch the object. Don’t pull too hard, yet firm enough to make sure both jaws sit flat against the object’s inside edges.

-
-
Gently remove the object from the jaws, being careful not to bump or shift the jaws.
-
Twist the locking screw clockwise to tighten it and lock the jaws in place.

-
When you're done using your digital calipers, clean the jaws with a cloth or rag, press the on/off button to turn the calipers off, and store it in its original case in a safe location.
