Multimeter brand/multimeter brand introduction

< , - Multimeter
, - Not only can it be used to measure the resistance of the object being measured, but it can also measure AC and DC voltage. Some multimeters can even measure the main parameters of transistors and the capacitance of capacitors. Fully mastering the use of multimeters is one of the most basic skills in electronic technology. Common multimeters include pointer multimeters and digital multimeters. An analog multimeter is a multi-functional measuring instrument with a meter as the core component. The measured value is read by the pointer of the meter. The measured values of digital multimeters are directly displayed in digital form on the LCD screen, which is easy to read, and some also have voice prompt functions. A multimeter is a meter that combines a voltmeter, ammeter and ohmmeter into one meter.
< - Several major multimeter brands, -

It is also the only large-scale manufacturer of industrial and civilian products in my country. Spectrum analyzer company. It has successfully passed the quality certification system and obtained the title of Shenzhen High-tech Company.
< - Repair methods for multimeters, - When looking for faults, you should first find the outside and then the inside, first the easy and then the difficult, break it into parts, and make key breakthroughs. The methods can be roughly divided into the following types:
, -. The sensory method relies on the senses to directly determine the fault factors. Through appearance inspection, it can be found such as broken wires, desoldering, short circuits, and broken fuse tubes. , burned components, mechanical damage, lifting and cracking of copper foil on printed circuits, etc. can touch the temperature rise of batteries, resistors, transistors, and integrated blocks. You can refer to the circuit diagram to find out the factors causing abnormal temperature rise. In addition, you can also use your hands to check whether the components are loose, whether the integrated circuit pins are firmly inserted, and whether the transfer switch is stuck. You can hear and smell whether there are any strange sounds or smells.
, -. The voltage measurement method measures whether the operating voltage of each key point is normal, and can quickly find the fault point. Such as measuring/converter operating voltage, reference voltage, etc.
, - .Short-circuit method. The short-circuit method is usually used in the above-mentioned checker/converter method. This method is often used when repairing weak current and micro-electrical instruments.
, - The circuit breaking method disconnects the suspicious part from the complete machine or unit circuit. If the fault is not found, it means that the fault is in the disconnected circuit. This method is mainly suitable for situations where there is a short circuit in the circuit.
, - .Measure component method. When the fault has been reduced to one or several components, it can be measured online or offline. If necessary, replace it with good components. If the fault disappears, it means the component is broken.
, - The interference method uses the voltage induced by the human body as an interference signal to observe the changes in the liquid crystal display. It is often used to check whether the input circuit and display parts are intact.
