Tape measure is a soft measuring tool made of plastic, steel bar or cloth. It is easy to carry and can also measure the length of some curves. The measuring tape used in the apparel industry is also a tape measure, also known as a soft tape. The materials used are PVC plastic and fiberglass. There are many scales and numbers on the tape measure, so what do you think of the tape measure?
Steps to use tape measure
Step 1: Prepare a ruler. We notice that the switch button on the ruler is closed.
Step 2: Turn on the switch, we can pull the ruler at will, stretch and shrink automatically.
The third step: the 0 scale of the ruler is tightly attached to one end of the object, then we keep it parallel to the object, pull the ruler to the other end of the object, and close to this end, and close the switch.
Step 4: Keep the sight line and the scale on the ruler vertical, and read the data. record it.
Step 5: Turn on the switch, retract the ruler, close the switch, and put it back.
What about tape measure
1. Direct reading method
During the measurement, the zero scale of the steel tape is aligned with the starting point of the measurement, and an appropriate pulling force is applied, and the scale on the ruler corresponding to the end point of the measurement is directly read.
2. Indirect reading method
In some places where the steel tape measure cannot be used directly, a steel ruler or a square ruler can be used to align the zero scale with the measuring point, and the ruler body is consistent with the measurement direction; use the tape measure to measure the distance of a full scale on the steel ruler or the square , Yu Chang measured by reading method. Tips: The general label of the tape measure is calculated in millimeters, a small grid is one millimeter, and 10 grids is one centimeter. 10, 20, 30 is 10, 20, 30 centimeters. The opposite side of the tape measure is the city scale: city ruler, market inch; the front of the tape measure is divided into upper and lower parts, one side is the metric scale (meter, centimeter), and the other is the inch scale, (feet, inches).
Notes on using tape measure
The tape of the tape measure is generally chrome, nickel or other coatings, so keep it clean, and do not rub it with the surface to be measured during the measurement to prevent scratches. When using a tape measure, the tape should not be pulled out with too much force, but should be pulled out slowly, and it should be returned slowly after use. For the brake-type tape measure, you should first press the brake button, then slowly pull out the tape, press the brake button after use, and the tape will automatically rewind. The tape can only be rolled, not folded. It is not allowed to put the tape measure in a place with moisture and acid gas to prevent corrosion. In order to facilitate use at night or in a dark place, some steel tapes are coated with luminescent material on the line surface of the tape, which can glow in the dark, so that people can see the line and numbers clearly, and care should be taken to protect the coating film during use .
The above is the introduction about how to see the tape measure, the use of the tape measure and the precautions. In fact, if you want to know how the tape measure looks, you should first understand the digital information above. The numbers on the tape measure are divided into two rows. The unit of numbers in one row is centimeters (CM), and the units in one row are inches. 1CM ≈ 0.3937 inches. 1 inch is about 2.54CM, and we generally look at centimeters in use.
