Do you know what the error control method of customized Measurement instrument is? Let’s take a look at it briefly!
In the actual measurement, it is necessary to reduce or even eliminate the influence of temperature on the length of the customized Measurement instrument as much as possible. Therefore, it is necessary to select a measurement environment with a suitable temperature. In addition, the size, material, and accuracy of the measured object will all have an impact on the measurement result. Specific attention needs to be paid to the following aspects: To ensure the stability of the measurement environment. In the actual measurement, the judgment of the environmental temperature stability is the maximum range of the environmental temperature change within one hour. For the measurement of the length customized Measurement instrument, the temperature of the environment can produce some changes, but no sudden changes, especially when the accuracy of the measurement is very high. The temperature change needs to be controlled within 0.5°C.

If you want to achieve good temperature control, you can install a constant temperature device indoors to understand the temperature changes in time, so that the measurement may be stopped in time when the temperature changes suddenly. At the same time, the number of door openings and closings in the measurement environment should also be controlled, because the air flow will also affect the temperature, leading to errors in the measurement. In addition, the temperature of the measuring personnel should be lowered to reduce the influence of the temperature of the measuring personnel on the surrounding temperature, so as to ensure the stability of the temperature in the measurement environment, improve the accuracy of the measurement, and reduce the effect of error. Therefore, when measuring, the surveyor reduces the large floating movement, while reducing its own temperature, avoiding excessive movement that affects the air flow. Also make sure that the temperature of the workpiece and the standard is the same. The temperature of the workpiece to be measured must be the same as the temperature of the standard, and at the same time, to ensure that the workpiece and the standard are kept isothermal under certain conditions. Because only the temperature of the two are consistent, the accuracy of the measurement results can be ensured. Because the size of the workpiece is different each time, when measuring, if the size of the workpiece is large, the corresponding temperature deviation will be reduced. On the contrary, if the size of the workpiece is small, the corresponding measurement temperature deviation can be appropriately increased, but it must not exceed the normal error range. If the temperature deviation in the measurement environment is too large, the size of the workpiece will change greatly, and it will also have a certain impact on the accuracy of the measurement. Therefore, if you want to ensure the accuracy of the measurement, you need to control the temperature change of the measurement environment. In particular, there should be no sudden changes in temperature, so you must first find a suitable temperature measurement environment before taking the measurement to reduce the occurrence of unexpected situations.
The above is about the error control method of the customized Measurement instrument.
