Mastering the knowledge of instrument maintenance is a basic skill that users should have, because the maintenance of the instrument is related to the instrument's integrity, usage rate and success rate. Therefore, the maintenance and maintenance of the instrument can be described as a part of the experiment and production. Once the instrument absorbs dust and dirt, it will affect the performance of the instrument, shorten the service life and directly affect the experimental results.
Most of the dust is tiny dust particles with a small amount of static electricity, which often float in the air, move with the airflow, and adhere to the object, almost no holes. Dust attached to the model specimen will affect the color. Dust on the moving parts will increase the wear and tear on the electrical parts. There will be dust on the electrical appliances, which will cause short circuit and electric leakage. The dust on the precious precision instruments will seriously make the instrument unusable.
There are many ways to remove dust, mainly depending on the condition of the dust-attached surface and the degree of dust adhesion. In the dry air, if the dust is less or the dust has not been wetted into a patch, use a dry cloth wipe, a towel brush, a soft brush, etc. to remove dust from the general instrument, or use a vacuum cleaner to vacuum.
For expensive precision instruments, such as optical instruments, instrument heads, etc., dust removal by the above method will also damage the instrument. In this case, special dust removal tools should be used to remove dust, such as wiping with lens paper and wiping cotton balls with alcohol.
In the humid air environment, when the dust has formed into a scale, the dust should be wiped with a damp cloth, but the surface of the faded surface and the appliance should not be wiped with a damp cloth. If the dirt is not easily wiped clean, wipe it with a cotton ball dampened with alcohol or wash it.
