As a high-precision precision instrument, any small external factors may bring measurement accuracy errors. So, which external factors have a greater impact on the imager and need our attention? The main external factors affecting the quadratic image instrument include: ambient temperature, ambient humidity, ambient vibration, environmental health and other external factors.

Below, Handing will introduce in detail the external factors that affect the measurement accuracy of the quadratic image instrument.

1. Ambient temperature

As we all know, temperature is the most important factor in the measurement accuracy of the imaging instrument, because the measuring instrument is a precision instrument, so some of the production materials will be affected by thermal expansion and contraction, such as grating ruler, marble and other parts. Generally, there are strict requirements for measuring temperature, the temperature is generally 20 ° C ±2 ° C, and there will be some changes in accuracy beyond this range.

Therefore, the computer room using the imaging instrument must be equipped with air conditioning, and pay attention to the use of air conditioning. First, try to turn on the air conditioning 24 hours, or at least ensure that the working time is open; Second, ensure that the imager is used under constant temperature conditions, and then measure after the temperature of the machine room is stable; Third, the air conditioning outlet should not be directly facing the instrument.

2. Environmental humidity

Many companies may not pay attention to the impact of humidity on the imaging instrument, because the instrument has a large range of acceptable humidity, and the general humidity can be between 45%-75%. However, it should be noted that many parts of precision instruments are easy to rust, and once rust will greatly cause precision error. Therefore, pay attention to air humidity control and try to keep the equipment in a more suitable humidity environment. Pay attention especially during the rainy season or in areas that are already wet.

3. Environmental vibration

Vibration is a common problem for the image instrument, and it is difficult to avoid air compressors, punching machines and other heavy equipment with great vibration. Attention should be paid to controlling the distance between these vibration sources and the image instrument. However, some enterprises will install shock-proof foot pads on the image instrument to reduce the interference of vibration on the image instrument and improve the measurement accuracy.

4. Environmental health

Image instrument this kind of precision instrument has certain requirements for environmental health, if there is dust in the environment, it will float on the image instrument and measurement workpiece, and then lead to measurement errors. Especially in the measuring room there are some oil, coolant, etc., be careful not to let these liquids stick to the workpiece. Usually pay attention to cleaning the measuring room health, in and out of the personnel should also pay attention to health, to wear clean clothes, in and out to change shoes, reduce the outside dust oil stains into the measuring room.

5. Other external factors

There are also many external factors that may affect the measurement accuracy of the imager, such as the power supply voltage. Since the imager needs a stable voltage when working, the general enterprise will install equipment to control the voltage, such as a voltage regulator.
