How To Read A Tape Measure Pdfl 'LINK'

I saw this on Facebook and thought it would be a cool Christmas gift for our son in law. After I received it I think I'll have to buy him another one. This is a well built 25' tape measure that is easy to read and the built in pencil is a fantastic idea.

How To Read A Tape Measure Pdfl

It is super handy and easy to use for projects. Particularly woodworking and drywall work. It's super easy to drag a straight line down a large sheet of material to make a long cut. Or pre-set the tape measure with a measurement and make your mark in hard to reach places.

Another stocking stuffer for my hubby for the win! My hubby is so used to stealing pencils from inside I had to remind him of the built in graphite marker a couple of times. But now he's so used to it when he grabs a different tape measure he's peeved he's gotta revert an old fashioned pencil!

For tools, besides my Quickdraw tape, I've got a chop saw, a skill-saw, a screw-gun, and a plainer, but no table saw, so, I'll measure, and mark with the quickdraw, then cut the boards to 38" using the chop saw.

You need to take a quick measurement, but how can you decipher all the markings on your measuring tape? The lines on your tape measure make it easier to get a precise reading, and it's pretty easy to figure out how to read your measurement once you understand them. We'll walk you through what each line represents on your tape measure so you can accurately find the size of any object.

Laser tape measures are alternatives to traditional metal tape measures; they're used to calculate lengths, widths and heights of up to about 650 feet (198 meters). They're generally considered accurate to within an eighth of an inch (3 millimeters) when measuring a distance of up to 300 feet (91.5 meters). Laser tape measures are used mainly by contractors, insurance adjusters, architects, flooring professionals and other people who do a lot of measuring. However, homeowners can easily use laser tape measures around the house, too.

To use a laser tape measure, you place the device on one end of what you want to measure, and then aim the laser beam so that it hits an object at the other end. If there's no wall, pole or anything like that, you can put a target at the spot you want to measure up to. The process is similar to using a conventional tape measure, except you use a laser beam instead of metal tape. Once you have the laser at the right spot, press the button, and the tape measure calculates the distance and displays it on its screen. The calculation is done through precision optics and laser physics using the phase-shift method, in which a laser hits an object and compares its reflection with the beam sent out, or using the time-of-flight method in which the time it takes for an optical pulse to reflect back is calculated. Some laser tape measures let you measure multiple distances and add them together automatically.

Laser tape measures are normally quicker to use than conventional ones, and you avoid the inaccuracies that can be caused by a twisted or sagging tape measure. Plus, it's easier to read a digital display of the measurement than to count little lines on a tape measure. Laser tape measures also eliminate the complications of measuring high ceilings and other hard-to-reach spaces.

You need to measure length accurately to do things like make a dress, build a house, survey a plot of land, or determine if the home team made a first down on the football field. These length measurements and many others are often made with the help of a measuring tape.

Some manufacturers use highly accurate reference tape measures to print their familiar hash marks on the tape. Some are printed using computer-controlled ink printers with tiny printheads to ensure the markings are laid down accurately.

At one end of the bench is a device called a laser interferometer, which can precisely measure distances along the tape. Laser interferometers work by splitting a laser beam in two. One of the beams, the reference beam, goes directly to a detector, while the other, a measuring beam, goes toward a reflector on the side of the microscope. The measuring beam bounces off the reflector and rejoins the reference beam back at the detector.

As the microscope moves over the tape, manufacturers can compare the position of the hash mark on the tape with the distance reported by the interferometer. If the tape is accurate to within an acceptable tolerance, it passes the test, and the batch that it comes from can be sold. To be used for buying and selling goods, a 1.82-meter (6-foot) tape should be accurate to within 0.79 millimeters (1/32 inch), according to NIST Handbook 44, a sourcebook for many measurement standards. Even more accurate tapes are available, such as those used for the Olympics or to measure the level of oil tanks, but they are more expensive.

Tapes are used in surveying to take linear measurements. They are available in different lengths and can be made of different materials. The 5 most common types of tapes used in surveying are discussed in this article.

Linen tapes are light in weight and easy to handle. These tapes may shrink when exposed to water and also elongate when pulled. Hence, these tapes are not suitable for accurate surveying measurements. These are generally used for measuring offsets and for ordinary works.

Steel tapes are not flexible and are suitable for measuring leveled surfaces only. They may corrode easily when exposed to moisture and to prevent this tape, it should be cleaned and oiled after every use. These tapes are generally used for standardizing chains, measurements of constriction works, etc.

Synthetic tapes are made of glass fibers coated with PVC. These are light in weight and flexible. They are available in lengths of 5m, 10m, 20m, 30m, and 50m. Synthetic tapes may stretch when subjected to tension. Hence, these are not suitable for accurate surveying works. However, synthetic tapes are recommended in place of steel tapes where it is essential to take measurements in the vicinity of electric fences and railway lines, etc.

The coefficient of thermal expansion of invar alloy is very low. It is not affected by changes in temperature. Hence, these tapes are used for high precision works in surveying such as baseline measurement, triangulation surveys, etc. Invar tapes are expensive than all the other types of tapes. These tapes should be handled with care otherwise bends or kinks may be formed. 350c69d7ab
