Whether we are buying a lightning protection component tester or other testing equipment, one thing to pay attention to is to understand the relevant operating specifications of components and common sense of specific safety regulations. For example, when buying a lightning protection component tester, we must first read the relevant product instructions, so that we can quickly understand the product, and also prevent some irregular operations from affecting the detection or the instrument. In itself brings some damage. Many people don't know much about the lightning protection component tester. How do we use the lightning protection component tester? Let's make a brief introduction.
The method of using the lightning protection component tester is actually relatively simple. First of all, we need to pay attention to the voltage requirements of the power supply of the lightning protection component tester. Under normal circumstances, it is 220 volts, and there will be AC ​​power on the back of the instrument, and a three-terminal socket. In addition, it should be noted that the key switches on the instrument need to be all pushed to the high position, and then the adjustment buttons are placed in the small position, and then the power switch is turned on. After preparing these tasks, you need to do it. For the test of the pressure-sensitive circuit, place the varistor at a high position. After the voltage preset is adjusted to a high level, turn on the high-voltage key and adjust the high-voltage limit to adjust the high-voltage preset.
Perform measurement after zui, connect the varistor to be tested and then the high-voltage start-stop button. After pressing the test button, some numbers will be generated. If the current is less than one milliamp at this time, the test data is ineffective, and the test needs to be performed again, and during the test, we also need to pay attention to the relevant inspection work.
First you need to check the varistor. After the inspection is completed, test the discharge tube. Connect the tested discharge tube to the test line. If a beep sounds, drop the tested discharge tube and click the test button. The green display After the light is on and there is no beep, then the value displayed on the display at this time is the measured value. After zui, the continuous detection can be tested by adjusting the continuous key to zui low. After the test is completed, click the high voltage button to turn off the high voltage.
The lightning protection component tester is equipped with a range (test range) adjustment function. In use, the test voltage can be reduced as much as possible to reduce energy consumption, extend the life of the lightning protection component tester, and reduce safety hazards. It can also reduce test time and improve work efficiency. And can be used for group screening, inspection and discrimination. Users can take full advantage of this feature.
