     The automatic image measuring instrument is a high-end measuring instrument, which also has certain requirements for the use environment. The following aspects need to be noted:
     1. Vibration isolation: If the automatic image measuring instrument is subjected to additional ambient vibration, the measurement accuracy will be reduced. When the frequency is less than 10Hz, the amplitude of the surrounding vibration should not exceed 2μm (peak-to-peak difference); when the frequency is between 10Hz and 50Hz, the acceleration should not exceed 0.4Gal. If the vibration exceeds these limits, anti-vibration measures should be taken (such as installing vibration dampers).
     2. Dust-free: The components of the automatic image measuring instrument need to be dust-free. Although the dust cover has a certain protective effect on the automatic image measuring instrument, the measuring instrument should still be cleaned regularly.
     3. Voltage stabilization: The power supply uses 90 ~ 264VAC, 47-63Hz, stable power supply under 10Amp to ensure the normal operation of the instrument.
     4. Temperature: Keep the temperature at 20 ℃ ± 1 ℃ as much as possible. Please do not adjust the machine accuracy at high or low temperatures. Otherwise, the accuracy of the measuring instrument at 20 ° C cannot be guaranteed.
     5. Humidity: Humidity has no direct adverse effect on measurement accuracy. However, high humidity can rust the mechanical surface and hinder smooth axial movement. Therefore, it is recommended to keep the ambient humidity between 30% and 80%.
     6. Illumination: The image measuring instrument cannot be placed under strong light or direct sunlight, otherwise it will affect the measuring accuracy of the measuring instrument. It will interfere with the judgment of the sampling point of the instrument itself.
     All of the above needs to be noted, some affect the accuracy, some affect the life, and some will directly affect the normal normal measurement.
