First, measure the bare diameter of a single strand and locate the circular mils value in the row that matches your measurement. Diameter information in the table applies to solid wires only. Since calipers are such useful tools for all sorts of Makers, we thought we’d share with the Make: community. Vernier Depth Gauge. There are two sets of numbers on the gauge. Code inspectors measure the diameters of wires to be sure they are safe for use in buildings. The meter will need a 4 terminal Ohm-meter function. Lower the thin stick-like metal rod sticking out of the back end of the calipers into the hole until it touches the bottom. Made-in-China.com helps global buyers match their buying requests with the right supplier efficiently. Muncy™ Quick Check Calipers can be used horizontal or vertically using just the edges of the jaws. Below is the experiment on how to measure the diameter of a given wire using a screw gauge. Go to the big-box store and get some scrapes of marked wire from the electrical clerk. The number above the slot is the size. How to use measuring tools (Vernier Caliper, Micrometer Screw Gauge and Dial. If you must be absolutely positive of the correct answer, then you will need to get a micrometer, and follow the methods described above. You can also measure the resistance of a meter of cable using 4-point (kelvin) connection (http://en.wikipedia.org/wiki/Four-terminal_sensing), After that, you can use any online tool to obtain the AWG from the resistivity. To gauge wire, you’ll first need to strip the wire, then use a wire gauging tool to measure its diameter. It appears that someone has respooled a number of the reels, as there are (at least) multiple reels all labeled "22 gauge" with different diameter wire on them. Insert the object to be measured and close the jaws. MathJax reference. The unit (it is a titanium knee) that the calipers will routinely measure has 5 seperate features / profiles that need measuring. I also had little luck finding a wire-gauge to stranded-wire-diameter table. Digital Depth Gauge. How to use measuring tools (Vernier Caliper, Micrometer Screw Gauge and Dial.
