As a precision measurement tool, micrometers (also known as spiral micrometers) are widely used in precision machining and are well known by people in the industry. The editor in the previous tweet "Have been using a micrometer for so long, are you really using it correctly?" "The correct method of using a micrometer is explained in detail, and it has been liked and forwarded by friends. Today, let's change the angle and take a look at what mistakes we are afraid of using micrometers.

Micrometers are divided into two types: waterproof and non-waterproof. The non-waterproof type is not waterproof. Spraying water or other liquids directly onto the ruler body will cause the micrometer to rust, so please use it with caution.

Storage Tips
Improper storage methods will also shorten the service life of measuring tools. It is recommended:
1. Store in a place with low humidity, good ventilation, and no dust.
2. Avoid direct sunlight to prevent damage to the LCD screen.
3. When storing, leave a gap of about 0.1~1mm between the two anvils.
4. Do not store the micrometer in a locked state.
5. After use, store it in a special storage box. Please store the storage box properly and do not place it directly on the ground.
Pay attention to maintenance during daily use of measuring tools to extend the service life of measuring tools. Also, be sure to use it according to the instruction manual.
