How to Use Bench-top Digital Multimeter?

Multimeters are one of the necessary instruments for hardware engineers, they can measure voltage, current, resistance, capacitance, diode, etc. Nowadays, portable multimeters and clamp multimeters as common ones in the market, and it is rarely known by people how to use bench-top multimeters. Now we'll briefly introduce it by taking Suin SA5053 digital multimeter as a sample. Hope it will do some favor in your everyday's testing and measuring work.

The using method of bench-top multimeters and portable multimeters has some differences, although the basic principle is the same. Actually, it is very easy to use bench-top multimeters. There is a red terminal in the red testing lead, and a black terminal in the black testing lead, which is the same with common multimeters, red test lead is positive polarity, black test lead is negative. This test lead kit will be used during parameter measuring.

Before using it, the Null setting is the first step to do which is can't be ignored. Then choose the suitable parameters to test according to the under-tested component or instruments. Eg., to test DC voltage, the DCV function should be chosen in SA5053, while not other functions like DCI, ACI, resistance, or capacitance. Please be noted to choose the suitable voltage range to test. If the voltage of the under-tested instrument is out of range, SA5053 can't display the testing result and may be burned. After everything is set OK, contact the positive and negative polarity by red and black test lead kit stably, and the measuring result will be shown in the SA5053.

Some tips for users when using digital multimeters are as followings:

1. Please read User's Manual carefully before using it to learn the function keys and measuring range.

2. Make sure to set suitable function and range, input voltage or current shouldn't be surpassed the maximum range to protect the internal circuit from being damaged.

What is the working principle of die cutting machine?

图片
Die cutting machines are essential tools in the world of crafting and manufacturing. These machines are used to cut various materials such as paper, fabric, and even metal into specific shapes and designs. The working principle of a die cutting machine involves a combination of mechanical and hydraulic processes to achieve precise and efficient cutting. At its core, a die cutting machine operates by using a die, which is a specialized tool that is used to cut, shape, and form materials into specific designs. The die is typically made of metal and is created with a sharp, blade-like edge that is used to cut through the material. The die is mounted onto a flat surface, and the material to be cut is placed on top of it. The machine then applies pressure to the die, causing it to cut through the material and create the desired shape. The working principle of a die cutting machine can be broken down into several key components: 1. Die: The die is the primary cutting tool used in the machin...

What is flexible coupling?

图片
  A  flexible coupling  is a mechanical device whose main function is to connect two shafts and transmit power. Compared with traditional rigid couplings, flexible couplings are flexible and can absorb axis misalignment and vibration. They are designed to reduce shock and noise in mechanical systems while increasing overall system efficiency and longevity. There are many types of flexible couplings, including flexible disc couplings, elastic sleeve couplings, universal joint couplings, etc. These different types of couplings are suitable for a variety of applications, such as high-torque transmission, high-speed operation, and high-precision alignment. The advantage of choosing a flexible coupling is that it can adapt to axis misalignment and reduce vibration and noise during equipment operation. This helps protect other components of the mechanical system and prolongs its service life. In addition, flexible couplings can simplify installation and maintenance and increase...
