When is it suitable to use the spectrophotometer and computer color matching system to assist color matching? Color sensing systems such as rice, gray, coffee… △ E: color difference can be seen when the color is above 0.4. Therefore, it is recommended to use spectrophotometer and color spectrum computer color matching system to match such colors, so that the efficiency can be greatly impro...
I.Electric equipment’s reaction to lightning surge Most people are familiar with the existence of a lightning surge voltage test. It is mainly used to evaluate the surge resistance of railway signal equipment connected to the power line. But do you know what the implications of a lightning surge would be for electronic devices? Here is a brief explanation of the effect a lightning surge can have...
Introduction In the field of lighting measurement, goniophotometry is an important approach since it is used to properly quantify the angular distribution of the light produced by luminaires. To conduct these examinations, specialized instruments known as goniophotometers are used. As a result of advances in technology, goniophotometers have undergone several iterations of development. This articl...

Ipx56 waterproof can also be called ipx56 waterproof Jet Test chamber, strong flush test chamber and other names. It can conduct ipx5 or ipx6 waterproof test on the shell of the product. Their meaning is that ipx5 is to prevent the...
Ring wave generator is a commonly used electronic test device that can generate numbers with a specific frequency, which can be used for engineering and scientific research, experiments, testing, calibration and debugging. They are widely used in engineering and research experiments to meet various frequency and time domain requirements. What is a ring wave generator? A ring wave generator is a co...
I.IK rating testing is what? IK is the shock and protection grade of the device shell. Generally, the protection requirements of IK and IP are both present. For outdoor electronic devices, whether suspended, buried or ordinary outdoor placement, they need corresponding IP and IK requirements. The IK test is determined by the Joule free fall impact of the pendulum. The specific reference standards ...

It is applicable to IPX1 and IPX2 waterproof grade test of products. Wall-mounted structure: the rack is fixed against the wall to ensure the smooth operation of the raindrops. The equipment frame is made of aluminum profil...
In order to assess the electrostatic discharge (ESD) immunity of electronic devices and systems, GB/T17626.2-2006 is a newly released standard in China. The ESD test is intended to examine the disturbance immunity of devices or systems to external ESD, and there are two discharge methods for ESD immunity testing, contact discharges and air-gap discharges. Contact discharges are preferred, but only...
EMC (electromagnetic compatibility) includes two parts: EM (electromagnetic sensitivity) and EMI (electromagnetic interference). Usually we call solving the EMC problem. In fact, it is to solve the external radiation interference of electronic equipment, or how to prevent equipment and electronic components from being interfered by electromagnetic wave interference from the outside world. To learn...
