China wholesale Video Measurement Machine - Manual type 2D Video Measuring Machine – Handing

① Temperature and humidity
Temperature: 20－25℃, optimal temperature: 22℃; relative humidity: 50％－60％, optimal relative humidity: 55％; Maximum temperature change rate in the machine room: 10℃/h; It is recommended to use a humidifier in dry area, and use a dehumidifier in humid area.

② Heat calculation in the workshop
·Keep the machine system in the workshop operating in the optimum temperature and humidity, and the total indoor heat dissipation must be calculated, including the total heat dissipation of indoor equipment and instruments (lights and general lighting can be ignored)
·Heat dissipation of human body: 600BTY/h/person
·Heat dissipation of workshop: 5/m2
·Instrument placement space (L*W*H): 2M ╳ 2M ╳ 1.5M

③ Dust content of air
The machine room shall be kept clean, and the impurities greater than 0.5MLXPOV in the air shall not exceed 45000 per cubic foot. If there is too much dust in the air, it is easy to cause resource read and write errors and damage to the disk or read-write heads in the disk drive.

④ Vibration degree of machine room
The vibration degree of machine room shall not exceed 0.5T. Machines that vibrate in the machine room shall not be placed together, because the vibration will loosen the mechanical parts, joints and contact parts of the host panel, resulting in abnormal operation of the machine.
