How the AC test transformer prevents the overvoltage generated by the frequency conversion series resonance test device is a relatively simple problem, but the overvoltage caused by voltage fluctuation is difficult to appear when the overvoltage protection is set. Generally, the overvoltage of the frequency conversion series resonance test device will appear in the frequency sweep stage of the instrument, that is, in the process of finding the resonance point. Those who have used it know that in the process of finding the resonance point of the frequency conversion series resonance test device, the voltage and frequency have a parabola-like linear relationship. By default, the system finds the high voltage, that is, the apex of the parabola as the resonance point.

The short-circuit test system refers to what kind of short-circuit test is carried out by which equipment, and how long is the test time. But I have one thing to tell you, the short circuit test is a kind of destructive test, mainly to test the working condition of the used equipment in a crisis situation, or to test how strong the anti-destructive ability of the used equipment is. Just like a lot of equipment in the military must undergo a short-circuit test, some for 3 minutes or longer, in order to resist breaking calls against the enemy during wartime.

IPM-4 -
FM SYSTEMS, INC.
The IPM-4 digital video level master is used to measure the signal quality of your IP video network. This low cost meter makes 6 different level measurements give you the assurance that your IP video system is working within specifications. It measures the output levels of both the camera and the recorder end of the system in dBm so you can check the near-end and far-end signal levels simultaneously.

1. Full-color touch screen control. You only need to set the oxygen concentration value on the touch screen, and the program will automatically adjust to the oxygen concentration balance and sound prompt.2. The step proportional valve is adopted to greatly improve the accuracy of flow control, and the closed-loop control is adopted to automatically adjust the oxygen concentration drift program back to the target value during the test, which avoids the disadvantage that the traditional oxygen index tester cannot adjust the oxygen concentration during the test and greatly improves the test accuracy.
