Rain testers are used for external lighting and signalling devices and car hoods, which can provide simulation of different environments such as water splash tests in which electronic products and their components can be placed. ‘Travel time and usage. But when you try, do you know what is most important?
Product introduction
When we conduct the test, the duration of the test affects the validity of the test results. If the test period is too long, it does not match the natural rainfall conditions. If the test time is short, the rain will not enter the tested product and the test effect will not be obtained.
In addition, during natural rain, the direction of each rain cannot be the same, which means that the surface of the tested product covers different rain, so we put the product tested in a suitable environment for testing.
Water temperature thing
Heavy rains usually occur during summer when the temperature is high. However, since the rain can change the temperature when it rains, the temperature of the rain falling on the ground will not be great.
When the test is carried out under standard test conditions, there is no need to control the temperature of the water, but the water should be as close as possible to the temperature of the product being tested, to reduce the possibility of water condensation. Is produced in the tested product. Therefore, the test water temperature should be 15 ℃ 10 ℃.
What causes water stress?
The pressure of the rain lab is supplied by tap water. Sometimes the pressure is high, sometimes the pressure is low, and there is a lot of change, and it cannot meet the water pressure of these products directly provided by the standard.
Not only is power supplied with continuous water, but the required water pressure for the test can be maintained at all times to ensure that the test is carried out under normal water pressure.
In short, the lamp protection level test parameters are based on weather data for many years and simulate the most difficult natural conditions as possible, so at the same time the speed and repeatability of the test will be in the proper way to take into account to evaluate the product.
After knowing the important things mentioned above, we must know the functions of the rain gauge:
1)The rain tester can be used in workshops, laboratories and other places to perform IPX1-IPX6 waterproof tests.
2)Available box, swinging, to rotate and safety around not need to use special sales, save the entry price.
3)There is a large window at the door, the lights are placed on the rain and left to make the checks of the test mode.
4)Turntable drive: using an imported motor, the speed and angle can be changed on the touch screen (adjustable), adjustable in standard mode, and can control positive and negative rotation (ie flexible and flexible: suitable for power-on). Test product to avoid air
5)The test time can be set on the touch screen, and the setting range is 1 to 999,999 min (adjustable).
6)The spray angle of the nozzle is 40°, 90°, and 135° of the fixed direction and sprays water between turns. The flow rate of each nozzle is 100 ± 5 L/min (adjustable), and the flow rate displays a direct reading.
7)In order to use the rain sensor safely, we also have safety features such as overload current, short circuit protection, and ground protection, protection against water and alarm bell.
After understanding the function of rain gauge, how should we operate it?
1)After turning on the device and turning on the power, the controller will enter the custom shutdown interface.
2)After the program is completed, the rain gauge will stop automatically.
3)Open the door of the testing machine, but put the sample in the sample box of the lab, then close the door to run the test.
4)Do not open the door of the test machine during the test. You can see the changes in the test view and the test engine through the test view window. The temperature and humidity of the test sample will also be displayed on the meter.
5)Be sure to turn off the lights after the test.
