Shockproofing is to avoid falling as much as possible, or the impact with a certain acceleration. Most multi-user smart meters cannot
withstand this impact, which will cause damage to the watch's movement parts, and excessive violent movement must be avoided.
Anti-magnetic, magnetic fields are obvious in life, and many items are magnetic, such as mobile phones. A very significant thing is that smart meter equipment especially likes to use magnet-type equipment. Some meters do not induce magnetic fields, which will affect the normal operation of the meter. This kind of equipment will be replaced by quartz smart meters, which will directly lead to Intermittent stopping, if the mechanical watch is more terrible, sometimes it needs to be demagnetized before it can be cleaned.
The use of different brands of materials, parts, and different types of smooth oils also results in different maintenance costs. Different types of smart meters have different design structures and maintenance times. Ordinary brands will recommend maintenance once every 4 to 5 years. Like a smart meter with a tourbillon design, it is recommended to check the level of oil consumption in a year, so the cost will be less.
Too short maintenance and too long maintenance are not desirable. At present, some brands on the market can provide a five-year warranty. I think everyone should treat this problem correctly. Literally, maintenance and warranty are originally two concepts. This does not mean that smart meters require maintenance only after 5 years. After 5 years have elapsed, maintenance is required after 5 years. Due to the warranty service provided by the brand, After a 5-year warranty period, the warranty period is still 2 years. Therefore, after you have enjoyed the time of the warranty period and once again underwent maintenance, it is recommended to wash the oil once every 2 to 3 years.
The application of new materials in smart meter movements is indeed beneficial for reducing wear and extending maintenance intervals, such as the escapement fork, escapement wheel and balance wheel of monocrystalline silicon. For example, smart meters use monocrystalline silicon as a hairspring in the movement to ensure the accuracy and stability of the travel time and date display functions. But other smart meters that do not have this design are accidentally affected by large magnetic fields.
