How To Use Marine Digital Calipers

One of the essential marine equipment piece is the digital caliper. It is a kind of a measuring tool that comes with two jaws (one is movable and other is fixed). Some models come with a knurled wheel that makes the jaw moving easy, whereas in other models you need to press the thumb on the bottom and move the jaw to the wanted position. Digital calipers come with a set of buttons that serve to set the caliper to zero and switch inches to millimeters and vise verse. The good thing about this marine equipment is that you can read the measurements on a large LCD display. Digital calipers are not only easy-to-read, but also provide fast, error-free measurements as well. Although they are simple to use, take a look at our simple how-to-use guide.

  • First close the digital caliper and set it to read zero. If the reading is not zero, then open the jaws and wipe the surface with your thumb. Close the caliper and check if the reading is now at 0.000.
  • Digital calipers can read four kinds of measurements: outside, inside, step and depth. For outside measurements, open the jaw, place the caliper over the object you want to measure and slide the jaw to the point where this tool and the object meet. It might seem easy, but if you fail to set the caliper straight, you will not take accurate measurements.
  • Use the smaller jaw on the top, if you need to deliver accurate inside measurements. In this case you don't need to open the caliper. Simply place the inside measuring jaw into the space you want to measure and slide the other to outer part of the object.
  • For depth measurements, open the digital caliper and use the depth blade that extends from one to another end. If you want to measure the hole of something, simply insert the blade into the hole and read the exact measurements.
  • This piece of marine equipment offers compound measurements as well. You can measure the distance between two holes with equal diameter. Use the inside jaws to measure one of the hole's diameters. The reading is actually going to be the distance between the centers of these two holes.
