How to Use and Read Dial Caliper
1. Close the caliper all the way to make sure no light can be seen through the jaws. If there is this means the caliper needs to be clean thoroughly or there is a metal burr on the jaws that needs to be filed off.
2. With the clamp still closed, loosen the bezel nut and twist the outside of the dial until the needle is set to zero and tighten the bezel nut.
3. Clean the part that is being measured because this can greatly affect the precision of the measurement.
4. Determine which side of the jaw to use (inside or outside) based on what is being measured. The outside is used for gaps and holes and inside is used for thickness, length, width.
5. Open up the jaws and measure the part. Make sure that there is a snug feel when closing the jaws but that the part can slide in and out of the jaws without complication. Tighten the lock screw to hold the position on the caliper.
6. Before determining the measurement, know what the marks mean: Every mark equals 1/10 or. 1 and every 10 marks equal 1 inch and on the dial indicator, the number that the needle rest on needs to be expressed in thousandths so whatever number you receive should be multiplied by. 001.
7. When looking at the caliper there is a straight edge to the left of the dial indicator. First find how many inches the straight edge went past and then see how many tenths the straight edge went past and write this down. Now look at the dial indicator take the number under the needle and multiply it by. 001 and write it down.
8. Add all the numbers making sure the decimal places are correct.
Instead of using a vernier mechanism, which requires some practice to use, the dial caliper reads the final fraction of a millimeter or inch on a simple dial.
In this instrument, a small, precise gear rack drives a pointer on a circular dial, allowing direct reading without the need to read a vernier scale. Typically, the pointer rotates once every inch, tenth of an inch, or 1 millimeter. This measurement must be added to the coarse whole inches or centimeters read from the slide. The dial is usually arranged to be rotatable beneath the pointer, allowing for "differential" measurements (the measuring of the difference in size between two objects, or the setting of the dial using a master object and subsequently being able to read directly the plus-or-minus variance in size of subsequent objects relative to the master object).
The slide of a dial caliper can usually be locked at a setting using a small lever or screw; This allows simple go/no-go checks of part sizes.
