Does a certificate fall under instrument markings?

I don’t understand what it means\ud83d\ude33

Regarding the \"instrument markings\" you mentioned, if you are referring to the label on the instrument, then I can tell you clearly that the contents of that label do not include a certificate of conformity. The certificate of conformity and the instruction manual are both paper documents separate from the instrument. Furthermore, for mass-produced automatic control components, such as pressure transmitters for vehicles, pressure transmitters for water heaters, and so on and so forth – damn it, even pressure transmitters for bears – manufacturers usually do not provide a certificate of conformity for each individual product; instead, they issue certificates on a batch basis. Put simply, it’s about printing a piece of paper as proof that the instrument meets the quality standards at the time of production.

Many imported instruments lack certification certificates

For example, if a car factory produces 5,000 cars per month and turns to me for a certain control component, I’m not the only option available to them, and they’re not some easy opportunity that just appears out of nowhere for me. If they decide to work with me, there must be a lot of preliminary steps involved; if I decide to take on the order, there must be extensive research done first. Questions such as whether the quality can be consistent and whether delivery times can be guaranteed are important – what matters are those preliminary steps, not just the document that comes along with the goods during the supply process. .

In some companies, the quality management departments are completely useless and nitpicky; they create problems where none exist and only cause trouble for the company. :Two years before last, a customer bought some car meters; one of them stopped displaying any information one day. When it was taken back for inspection, I opened the meter’s casing and found that the power cable was broken. It was fixed by soldering it for just 5 seconds. Later, to deal with this ridiculous issue, he spent half a year struggling with it, which really upset him. . . The broken wire, who the hell knows? Did their workers pull it apart, or did it break due to the shaking of the vehicle? . . Who gives a damn about pen quality? Worrying over something with such an extremely low probability – something that only happens once every 20 years – is it worth it? What kind of junk is this? Later on, this person came back to my brother to buy a watch or something, but my brother refused to sell it. Brother doesn’t care about money; he works calmly and values freedom. .

It does not belong to instrument markings; instrument markings generally refer to stainless steel tag plates, which must indicate relevant technical parameters such as the model, tag number, medium temperature, and pressure

A certificate of conformity is not considered an instrument identifier. An instrument identifier is indicated on the instrument’s nameplate and includes details such as the model number, production serial number, measurement range, power supply requirements, output signal type, accuracy level, wiring methods, tag number, and device identifier. The manufacturer assigns these identifiers according to the customer’s requirements; if no specific requests are made, then standard identifiers are used: model number, serial number, power supply details, output information, wiring specifications, and company name

Experts know what this thing is, but management is usually made up of non-experts. Try to get everything together
