NOYAFA Electronic specializing in testing instruments and cable testers for 16 years
Cable fault tester is one of the common equipment for detecting cable faults. Its performance is stable, fast, accurate to find fault points, and maintenance personnel can quickly launch maintenance work, greatly providing work efficiency. The purchase of cable fault tester is also one of the common equipment for detecting cable failures.
Its performance is stable, fast, accurate to find fault points, and maintenance personnel can quickly launch maintenance work, greatly providing work efficiency. The purchase of cable fault tester is also a question that many friends pay attention. Next, we focus on purchasing the precautions.
Another case of power supply In recent years, the cable fault tester is damaged. 80% is due to poor wiring when the high pressure flashes, or the high voltage signal is stringed in the host, causing the instrument to damage if the battery is powered, even high pressure String, but the ground does not constitute a loop, can only cause a common mode effect, thereby completely avoiding the occurrence of machine damage. Collectors and laptops: Collector + notebook test solution is a design plan proposed in 1996, and put into implementation, launching "Cable Fault Test and Management System" in 1997, using a few years of market use In view, it seems that it does not adapt to China's national conditions. The principle of design considerations at that time is to give the user a good use tool, and the data processing power is a bit.
But due to the following reasons. Currently discontinued. The notebook + collector does not adapt to the on-site cable fault test:
However, most of the cable fault tests are in substations or outdoors, dust, large interference, and complicated environment, will greatly reduce the service life of laptops. And the sampling waveform is not good. 2, the switching power supply of the laptop can generally only use it in the case of the grid impact, and when the failure of the cable is high, the fluctuation of the grid is very volatility, which is very easy to cause the power of the laptop, so it is using a notebook. When the computer tests high-pressure flashes, it emphasizes the charging power supply to be disconnected, and the battery is tested.
3. Because the user wiring error causes high voltage to enter the laptop, in the cable fault test, the high-voltage string tester is a common problem due to wiring issues. The anti-impact capacity of the laptop is very weak, and the high voltage voltage passes the test line - collector - enters the laptop, will eventually lead to the laptop interface. Such lessons have encountered several cases in our customers.
Although current sampling can improve the security of the equipment, current sampling is more chaotic for close-range faults, making it often misjudged when testing closely. 4, computer viruses will affect the normal use of the equipment, which seems to have nothing to do with our equipment, but users inevitably enable the computer to be impacted by various computer viruses when using the computer, and take it out when the cable is problematic There will be a variety of problems, but not working properly. Thereby, delays are delayed.
Now the performance of the advanced cable fault tester should be equipped with the interface of the computer communication. The cable fault tester with computer interface is selected. The test waveform needs to be tested by the cable fault tester after the test is complete. In the laptop or other computer, archive, analysis, production test report, etc. Should be the best procurement plan. The above is about the purchase of cable fault tester. If you have any other questions I want to consult, you can continue to pay attention to Xiaobian.
