Firstly, daily maintenance and upkeep should be meticulous.

Daily maintenance may seem simple, but often it is not taken seriously by others. This is also the simplest way for people to overlook it. Many times, big problems are accumulated from small problems. Keep the surface of the instrument clean, check the voltage and power supply before use, observe whether the instrument functions properly, and fill in the usage record during use. Develop good habits of daily maintenance to avoid damage.

Secondly, equipment maintenance work should be handled seriously.

When the instrument malfunctions, information collection and preparation work should be carried out before maintenance, such as model, factory number, fault time, whether there is abnormal noise when the fault occurs, whether there is sudden power outage, and whether the instrument moves.

Pay attention to maintenance, remove fastening screws, and do not easily remove small parts to avoid loss, classification, and detachment. After the equipment maintenance is completed and installed, restore the original samples in sequence without any excess parts. The damaged parts should also be marked, and after replacement, they should be restored to their original state without any errors.

After the maintenance work is completed, it is necessary to clean the surface of the instrument, turn on the power, and see if it can work properly. Correct the instrument, restore normal working condition, and then use it by personnel. Try to see if the instrument has returned to its original working condition to avoid potential hazards. After Zui, clean up the site, check for lost tools, and fill out maintenance logs for inspection. In the process of instrument maintenance, regardless of leakage or cross infection, the protection engineer should always pay attention to the protection work. Unnecessary accidental injuries.

Three. Regular maintenance and inspection.

Regular inspections include visual checks, regular cleaning, more slippery and vulnerable parts, functional checks, and performance testing calibration. More importantly, check for safety.

security check:

1. Check if the rack is secure, if the mechanical operation is normal, and if there are any loose, detached, or broken connections.

2. Check various wires, plugs, connectors, etc. Whether the grounding wire is reliable, and whether the grounding resistance and leakage current are within the allowable range.
