mercruiser temp gauge pegs when grounding oil pressure wire
Why mercruiser temp gauge pegs when grounding oil pressure wire:
1. The grounding wire of the automobile instrument is connected to the shell of the instrument at one end, and the grounding wire of the automobile instrument connected to the grounding wire at the other end shall be thick enough. Generally, the grounding wire of 6 square meters shall be used, and the grounding wire shall not be too long. The length can be increased by 10% between the two terminal blocks. The grounding wire of the automobile instrument shall not be wound with other cables or wires; Yes, it is, but one consequence will be that power electricity interferes with the instrument signal, resulting in inaccurate instrument display, which is not acceptable in the factory. If the instrument is transmitted remotely, the consequences will be even worse. If the data is wrong, unexpected losses may be caused.
2. Instrument grounding is mainly divided into protective grounding and working grounding protective grounding to eliminate the accumulated static electricity. This kind of grounding is basically the grounding of the nearest shell. In addition, the working grounding is for the consent of the zero line between the field instrument and the system, to eliminate the potential difference of the zero line, so as to avoid causing signal distortion. This kind of grounding is generally led to the control system for unified grounding; 2 Operation step 21 All wiring at the instrument terminal shall be correct 22 Instrument wiring and grounding electrode E ˊ Potential probe P ˊ And current probe C ˊ After the instrument 23 is placed horizontally, adjust the mechanical zero position of the galvanometer, return to zero 24 and set the "multiplying switch" to the maximum multiplying power gradually.
3. The grounding resistance should be small, especially for large precision instruments; The # 160 four wire grounding resistance tester is controlled by a microprocessor. It can automatically detect the connection status of each interface and the interference frequency of the interference voltage of the grounding grid. It also has the function of testing the resistance value of the auxiliary grounding electrode and storing 500 groups of data at the same time. The resistance measurement range is 001 Ω~3000; It depends on what kind of pipes you use on the site, and then what kind of instruments you use. Generally, the instruments that are grounded are electromagnetic instruments, but now they generally have grounding electrodes. I hope they can help you when you are grounded; What should we do if the lightning protection and grounding test of the building is not qualified? Three people answered that they should know something about the project and life. June 26, 2015, they should share every bit of life together. Thank you for your attention. First, they should make up the grounding electrode before testing. If they are qualified, they can do the second lightning protection and grounding test. Step 1: All the wiring at the instrument terminal should be.
