1. Ambient temperature


      It is well known that temperature is the main factor in the measurement accuracy of the automatic imager. Because the measuring instrument is a precision instrument, some of the production materials will be affected by thermal expansion and contraction, such as grating scales, marble and other parts. Generally, there are strict requirements for measuring temperature. The temperature generally fluctuates two degrees above and below 20 ° C, and there will be some changes in accuracy beyond this range.

      Therefore, the computer room using the automatic imager should be equipped with air conditioning, and pay attention to the use of air conditioning. The air conditioner can be turned on for 24 hours, to ensure that it is turned on within 8 hours of operation; to ensure that the measuring instrument is used at a constant temperature, and then measure after the temperature of the machine room is stable; the third air conditioning port should not blow against the instrument.

      2. Environmental humidity

      Many companies may not pay attention to the impact of humidity on the measuring instrument, because the acceptable range of the instrument for humidity is relatively large, generally the humidity can be between 45-75. However, it should be noted that many parts of the instrument are prone to rust, and once rust will cause accuracy errors. So pay attention to air humidity control and try to keep the device in a more suitable humidity environment. Pay special attention to the rainy season or areas that are already damp.

      3. Environmental vibration

      Vibration is a relatively common problem for measuring instruments. It is difficult to avoid air compressors, punching machines and other heavy equipment with high vibration in the equipment room. Pay attention to control the distance between these vibration sources and the measuring instrument. There are also some small-amplitude vibration sources that need attention. If the small amplitude is close to the vibration frequency of the measuring instrument, it is a serious problem. But now companies generally install shock-proof equipment on the measuring instrument, which can reduce the interference of the vibration on the measuring instrument and improve the measurement accuracy.

      4. Environmental sanitation

      Measuring instruments have high requirements on environmental hygiene. If the hygiene is poor, dust and dirt will remain on the measuring instruments and measuring workpieces, which will cause measurement errors. Especially in the working machine room, there are some oils, coolants, etc. Be careful not to let these liquids stick to the workpiece. Normally, pay attention to cleaning the sanitation of the equipment room, and the personnel entering and exiting should also pay attention to the hygiene, wear clean clothes, change shoes when entering and exiting, and reduce the dust and oil stains from entering the equipment room.

      5. Other external factors

      There are also many external factors that may affect the measurement accuracy of the measuring instrument, such as the power supply voltage. The measuring instrument needs a stable voltage during operation. Generally, companies will install voltage control devices, similar to voltage regulators to control voltage.
