The difference between measuring instruments and measuring instrumentsA measuring instrument was a third-party standard used to measure certain attributes of a target. It usually had scales, volumes, and other units. The measuring device was a measuring device used during measurement. Both were used for measuring-related operations, but from the concept, the measuring instrument emphasized the standard of measurement, while the measuring instrument emphasized the instrument of measurement. However, this difference was subtle, and there might be some overlap and confusion in practical applications.

Kunshan City Meter External School Measuring and Measuring UnitWorldcom's measurement and measurement center was a power meter verification unit located in Kunshan City. It could perform instrument verification, calibration-making, and other projects. It provided engineering instrument calibration-making, engineering experimental instrument calibration-making, engineering measurement instrument calibration-making, and other services. The certificates and reports issued by the center were approved by the China National Academy of Sciences. It was a reliable third-party correction organization.

2010 Dimensional Measuring InstrumentThe 2D Measuring Instrument 2010 was as follows:
1. Equipment preparation: Turn on the computer, the two-dimensional measuring instrument, and other related equipment one by one, and click on the icon of the secondary measuring platform. Make sure that the appearance of the measuring instrument is not damaged, the components are intact, and the equipment is in normal working condition. At the same time, it was necessary to ensure that the measurement environment met the requirements of the measuring instrument, such as temperature, humidity, etc.
2. Placing the corrected version: Place the corrected version on the test bench with the character 2014 facing up. The corrected version should be placed horizontally on the test bench without any foreign objects blocking or tilting.
3. Lighting and camera adjustments: Find the circle on the correction board, turn off the LED light, adjust the lens resolution, and adjust the correction light (lower light); After clicking the image correction-three circles under the correction processing menu, move the three circles on the screen to the edge or inside of the reference circle. When you shake a dot, the left mouse button will show a blue circle (the reference circle should not leave the screen), and then click the right mouse button on the screen. The correction success and the zooming factor will appear. Then click OK, and then measure the reference circle.
4. Calibrating verification: After the completion of the measurement, the round hole on the standard part shall be measured. During the measurement, click the automatic capture of edge points and circle command, and then capture more than three points on the edge of the reference circle, click the right mouse button to draw a circle, and the size will be automatically generated. If the measured size are consistent with the standard size (tolerance: 0.005mm), the equipment is in good condition. On the contrary, if the tolerance is exceeded, the equipment may be abnormal. You should contact the auxiliary imaging instrument supplier in time.
5. Record data: After each verification, the examiner will record the amplification factor, verification time, verification and verification error value, so that the examiner can consider the error value during the actual inspection.
In addition, the correct input of the ball diameter parameters of the two-dimensional image measuring instrument also had an impact on the measurement accuracy. During the operation, it was also necessary to ensure that the input was correct, and pay attention to whether the compensation file was correct. If it was incorrect or lost, the measurement accuracy of the two-dimensional image measuring instrument would be inaccurate and unreliable. It needed to be re-verified and installed to obtain the correct measurement value.

Measuring the density of jadeTo measure the density of the jade, the soaking method could be used, as follows:
1. "Preparing tools: An electronic scale accurate to 0.1g, a glass of water (filled in a transparent glass), a string, and a jade object to be tested.
2. [Measuring the quality of the jade: Use an electronic scale to measure the weight of the jade and record it.]
3. Immerse the jade in water for measurement: Use a string to tie the jade, immerse it completely in water without touching the cup wall and the cup bottom (you can use a fixed support to hang it for more accuracy), and record the reading of the electronic scale at this time; then release the rope to let the jade sink to the bottom, and record the reading of the electronic scale again.
4. [Calculating density: Based on the data obtained, divide the jade's mass by the corresponding value to obtain the jade's density.] It should be noted that the thinner the string, the more accurate the measurement. If you encounter a small object that can't be tied with a string, you can use a jade string, light it, and stick it to the surface of the object to measure.

Speckle measuring instrument photographyDifferent speckles had different requirements and characteristics. For example, when the seventh generation of Visia was tested, it would test the left, right, and left sides and then take photos. During the test, it was not allowed to apply any sun protection or makeup, and it had to be cleaned before the test. When the AI intelligent skin detector was used, it would take photos in different directions according to the prompts, and it needed to remove makeup before the test. There were other related devices on the market, such as smart skin detection and freckle removal devices, but there was no mention of special requirements for photography.
