Open the jaws inside of an object to find the inner diameter. Push the extension rod into the object for a depth measurement. Look at the digital reading."
article: Slide the clamps closed and push the extension rod in all the way. Then, hit reset to display only zeros on the screen. Properly zeroed calipers are essential to getting an accurate measurement, so make sure to do this! Calipers have 2 large jaws that you can open and close around the outside of an object. These jaws are located at the bottom of the ruler part of the calipers. Open the calipers so they are wider than the outside of the object, and then close the calipers around the part of the object you want to measure. For example, to measure the length of a nail, open the calipers wider than the length of the nail and close them so that 1 jaw is touching the head of the screw and the other is against the pointed end of the screw. Find the inner measurement jaws on top of the calipers (above the part that looks like a ruler). These are smaller than the outer jaws. Close the inner jaws of the calipers and put them inside of the object. Open the calipers so the inner jaws are pressed against the inside of the object. For example, to measure the inner diameter of a pipe, open the calipers until they are pressed against the inside of the pipe to get your measurement. Locate the extension rod on the side (or end of the ruler section) of the calipers. Position the calipers against the top edge of the object or hole, and then extend the bar down into the hole or object until it touches the bottom. For example, to measure the depth of a hole, place the caliper jaws against the rim of the hole and extend the bar down into the hole all the way to the bottom. Look at the screen and record the number. Keep in mind that the readout will include a zero or whole number followed by a decimal and 3 digits behind it.  For example, the readout may say 0.365 in (0.93 cm) or 4.987 in (12.67 cm). Record the entire number as your measurement. Some digital calipers have a button to change the measurement from imperial to metric or vice versa. Check to see if this is a feature of your calipers and press the button if needed.

article:
The falsetto "register" (though it's more of a muscle placement than a register) lies at the top of your range. It's a different type of voice that can be found by experimenting with high-pitched sirens – that's when you mimic a siren on an "ooh" sound just like a fire engine or a police car. Do them from the top of your register; not to the top of your register. Start as high as can – that should be your falsetto. It doesn't matter if it sounds good, it just has to be a legitimate note. Many voice teachers tell their male students to start talking in their "little boy" voice. Talk like you're three or four years old – can you hear the difference? Can you feel the difference? It should feel more up and back, in the sinuses (or mask) of your face.  If that doesn't work, try imitating a woman's voice. You'll likely take on a breathy, airy tone, vaguely reminiscent of Marilyn Monroe. This is likely your falsetto. It's possible you're going into head voice, which is different. That voice will sound a little stronger and a little more like Minnie Mouse. If this sounds accurate, try finding a register that you can't feel in your throat – many singers speak of feeling a "muscle relief" with falsetto. Unless you're the next Pavarotti, you probably won't be able to produce much sound with falsetto anyway. So when you go to find it, don't push yourself (and definitely don't use your throat). Keep it quiet. You're Marilyn Monroe talking in a hushed voice, not Miley Cyrus screaming at the top of her lungs. You may find that if you try to sing louder, you'll fall into head voice. Does the resonance of your voice change? Do you start to feel it in your body? Then you're not singing in falsetto anymore. " Because of the way the throat and vocal folds are constructed, "aaa" and "aayyy" do not work well for finding falsetto. "Eee" and "oooh" are much more conducive to getting the sound up and into your mask and letting your vocal folds go. On this vowel, slide around from top to bottom. Do you hear how the timbre of your voice changes? When it gets really light towards the top and you feel fewer vibrations internally, that's your falsetto.
