What are the precautions when using a tape measure?

Usually, rulers are often used to measure some objects. The tape measure is better, which is convenient for measurement and has higher measurement accuracy. Pay attention to the correct method. Generally, when using a tape measure, first turn on the brake switch, then slowly pull out the tape measure, hook it on the edge of the object, pull it to the position to be measured, and take it back after reading directly or indirectly. There are some precautions when using tape measure. Let's learn about the usage and precautions of tape measure. First, how to use a tape measure

Tape measure is a common measuring tool in the family, which can be used to measure the length of various objects in life. Many friends have used tape measure, but they may not know the correct use of tape measure. So how do you use a tape measure?

1, most tape measures will have a switch beside them. To use a tape measure, you must turn on the switch before you can pull out the ruler. Some better tape measures have buttons in addition to switches, which helps to keep the ruler stable during measurement.

After the tape measure is opened, you can measure the object. When measuring, hook the edge of the object with the hook in front of the tape measure, and then stretch the ruler surface close to the surface of the measured object to the measuring position.

3. reading. There are two reading methods for tape measure. One is the direct reading method. When measuring, aim the zero scale of the steel tape at the starting point of measurement, apply appropriate tension, and directly read the scale corresponding to the measuring end point; The other is indirect reading. In some parts where steel tape cannot be directly used, steel ruler or square ruler can be used to align the zero scale with the measuring point, and the ruler body is consistent with the measuring direction. Measure the distance to a full scale on a steel ruler or square with a steel tape measure, and measure the remaining length by reading.

4. After the measurement is completed, loosen the tape measure and let it be automatically recycled. Pay attention to the sharp edge of the tape measure and be careful when recycling it to avoid cutting your hand.

Second, what are the precautions when using a tape measure?

As a measuring tool, tape measure should also pay attention to some matters when using. Precautions for using tape measure are as follows:

1, tape measure The tape measure is usually coated with chromium, nickel or other coatings, so it should be kept clean, and it should not rub against the measured surface during measurement to prevent scratches.

2. When using a tape measure, it is not advisable to pull it out too hard, but slowly. After use, you should also return to the original position slowly to avoid the excessive contraction force of the spring, which will cause the adhesive tape to scratch your hand.

3. Brake the tape measure, first press the brake button, and then gently pull out the tape measure; Press the brake button after the measurement, and the tape will be automatically wound. Tape can only be wound, not folded.

4. Don't put the tape measure in a damp and acidic place to prevent corrosion.

5. When using the tape measure at night or in a dark place, you can coat a layer of luminescent substance on the stripe surface of the tape measure, which can emit light in the dark, so that people can see the lines and numbers clearly, but pay attention to the protective coating during use.

6. After using the tape measure, it should be placed in a dry and protected place as far as possible to avoid collision and wiping.
