Whether we are buying a lightning protection component tester or other testing equipment, one thing that needs to be paid attention to is to understand the relevant operating specifications of the components and the specific common sense of the specifications and so on. For example, when buying a lightning protection component tester, we have to read the relevant product instructions, so that we can quickly understand the product, and can also prevent some irregular operations from affecting the detection or bringing the instrument itself. Come some damage. Many people don’t know much about the lightning protection component tester. How to use the lightning protection component tester below?
The method of using the lightning protection component tester is actually relatively simple. The first thing to note is that we must be clear about the voltage requirements of the lightning protection component tester’s power supply? Normally it is 220 volts, and there is an AC power supply and a three-head socket on the back of the instrument. In addition, one thing to note is that all the key switches on the instrument need to be pushed to the high position, and then the adjustment buttons are placed in a small position, and then turn on the power switch. After preparing for these tasks, perform a pressure-sensitive operation. To test the circuit, place the varistor at a high position, and after the voltage preset is adjusted to a large value, turn on the high voltage button and then adjust the high voltage limit and adjust the high voltage preset.
Finally, perform the measurement. Connect the varistor to be measured to the test and then the high-voltage start-stop button. After the test button is pressed, some numbers will be generated. If the current is less than one milliampere at this time, then the tested data has no effect and needs to be tested again, and we also need to pay attention to related inspections during the test.
First, check the varistor. After the check is completed, test the discharge tube. Connect the tested discharge tube to the test line. If there is a buzzer, put down the tested discharge tube and click the test button. The green display After the light is on and there is no buzzing sound, then the value displayed on the display at this time is the measured value. Continuous testing: Turn the continuous key to low to perform the test. After the test is completed, click the high-voltage button to turn off the high-voltage.
