The three elements of color: brightness, hue, and color saturation. In the LCH color space, L is brightness, C is saturation, and H is hue. In the RGB color space, R is red, G is green, and B is blue. In the LAB color space, L stands for brightness; A indicates the red-green bias, A represents the red direction, and A is negative represents the green direction; b indicates yellow-blue bias, b is p...
To ensure their goods can withstand even the most extreme circumstances, manufacturers often use a humidity chamber, a special device that simulates a variety of humid settings. It is also called a high and low-temperature test chamber. They may also observe the effects of humidity changes on their goods. Product parameters may be tested under extreme circumstances by manufacturers. Humidity chamb...
IPX12 drip tester has many names, such as rain drop testing instrument, rain drop testing machine, etc. The frame of IPX12 drip tester is composed of four aluminum columns. We use high-quality aluminum alloy materials. The weight of aluminum is lighter, and it will not be difficult to carry because it is too heavy. Moreover, aluminum materials have good corrosion resistance and are not easy to rus...
The glow wire test apparatus investigates the fire-resistant properties of raw materials and finished components. LISUN’s glow wire test equipment has been ergonomically designed to meet the above EN and IEC standards. Fire originates from the glow wire itself. A temperature programmer is used to establish and regulate the glow-starting wire’s temperature. By switching the temperature cont...
In its most basic form, a spectrum analyzer is a testing tool that evaluates a variety of circuit or system characteristics in the radio frequency range. Standard testing equipment would evaluate the quantity by calculating its amplitude over a certain period. It is also called a frequency analyzer. Voltmeters, for instance, use the time domain to measure voltage amplitude. We may thus expect a si...
In order to conduct realistic emission and susceptibility testing for radio frequencies, a line impedance stabilization network LISN-B is required by certain electromagnetic compatibility (EMC) and electromagnetic interference (EMI) test standards. LISN is also known as artificial networks (AN) or artificial mains networks. What Is conducted emissions testing? A radio frequency (RF) equipment or s...
To simulate EMI stress in the intended operating environment, a bulk current injection test is a conducted RF immunity test in which a modulated signal is injected into cables through a current injection probe. The DUT’s (and related PCB and external components’) resistance to electromagnetic fields connected to the communications line wire harnesses may be evaluated using bulk current...
A device that generates very brief spikes in voltage or current is known as an impulse generator SUG255. It may break down these gadgets into two categories: impulse voltage and current generators. Lightning and switching surges may damage electrical infrastructure. Thus it’s important to evaluate its resilience using high impulse voltages. Some nuclear physics experiments even make use of s...
The needle flame test is used to evaluate the fire danger produced by tiny flames, which may arise from the ignition of a malfunctioning component of electrical equipment. This kind of ignition may occur because of the needle-flame test. A needle flame tester is used for this purpose. The needle flame test uses simulation technologies to determine how likely a fault situation inside the apparatus ...
