What should I do if the results measured by the colorimeter are abnormal
Performance configuration of colorimeter:
1. “You need to know which colorimeter is suitable for your industry, and the requirements for color difference accuracy are different for each industry, that is, △ Eab. If △ Eab is between 0-1, you must choose an instrument with higher accuracy;”; These are generally rubber and plastic, paint and paint industries; If you do not need a relatively high accuracy, you can also choose a general color difference instrument.
2. You need to understand the shape of your product. Currently, the test aperture of the general color difference instrument is 4mm or 8mm; If your product has a curved surface or is very small in size, it is necessary to consider the issue of the test aperture; Of course, it can also be customized, such as:
Large aperture (LAV): 2.54 cm (1 inch)
Medium aperture (MAV): 1.5 cm (0.6 inches)
Small aperture (SAV): 0.75 cm x 1.0 cm (0.3 inches x 0.4 inches)
Ultra Small Aperture (VSAV): 0.3 cm x 0.8 cm (0.12 inches x 0.31 inches)
3. Is there a national metrological certification. This type of instrument is a metrological instrument. It is important to understand whether the product can meet national metrological requirements, otherwise there will be disputes, and your data will not be available for reference.
In general, for a color difference instrument that is worth purchasing, there are many factors worth considering in addition to the main factors mentioned above.
What should I do if the results measured by thecolorimeter are abnormal?
1. This situation is generally caused by the lack of black and white correction or inaccurate black and white correction, which requires a black and white board correction first. Dirt entering the measuring port can also cause inaccurate measurement.

The ipx9k High Temperature Pressure Jet Waterproof Test Chamber is characterized by a waterproof grade of 9, indicating high temperature and high pressure water spraying, and spraying high temperature and high pressure water in various directions of the shell for water spraying test. In addition, k represents a function of pressurization, and under such strict conditions, its water pressure will become stronger. The ipx9 is currently a high level of waterproof protection. The IPx9 High Temperature Pressure Jet Waterproof Test Chamber is also widely used in fields such as LED lighting fixtures, display screens, household appliances industry, automobiles, and automotive accessories. At the same time, all dust and waterproof equipment can be customized according to user needs. The ipx9k High Temperature Pressure Jet Waterproof Test Chamber has four different vertical spray angles, namely 0 °, 30 °, 60 °, and 90 °, and the water pressure can reach 8000 to 10000 Kpa; Moreover, its testing r

Capacitance  refers to the ability to hold a charge. It is a medium for realizing the storage and release of static charges, with the characteristic of permanent charge storage. Capacitor components are widely used in power supply filtering, signal filtering, signal coupling, resonance, filtering, compensation, charging and discharging, energy storage, and power separation in circuits. According to its ability to accommodate charges, it is generally measured in Farads, and the international unit is Farads. Therefore, capacitors are essential components for electronics and power. The role of capacitors: Bypass capacitors and decoupling capacitors are two devices that provide energy storage for local devices. Bypass capacitors can reduce load demand, make the output of the voltage regulator smooth, similar to a small rechargeable battery, and can be discharged and charged. The decoupling capacitor can smooth the edge signals of the device, so as to prevent the input signal from being too

1 General 1.1 Scope and object This International Standard(IEC61032) specifies details and dimensions of test probes intended to verify the protection provided by enclosures with regard to: – protection of persons against access to hazardous parts inside the enclosure; – protection of the equipment inside the enclosure against ingress of solid foreign objects. SMT IP10T_AL The object of this International Standard is: – to bring together in one publication object probes and access probes currently specified in other standards, together with any necessary new probes;    – to guide technical committees in the selection of test sphere; – to encourage those concemed to specify test probes in accordance with those already specified in this International Standard rather than modify details and dimensions; – to limit the further proliferation of types of test probe. 1.2 General recommendations When selecting probes, priority should be given to IP code probes. The use of other probes, particul
