Skills no longer make you feel confused, then take a few minutes to master some simple discrimination method, you can pick to a practical Whether the formation, with or without bump or tilt, choose smooth lossless; look at the color panel, black microcrystalline Germany Selinger Board and smooth surface of pure white Japanese NEG Panels are good panels, the general name of plants and manufacturers use; made of A-and B-class board while also white, but the rough edge of B-class board, not A-smooth; C-level board easy to yellow color, factory often printed pattern. To choose a panel of imports or domestic A-level panel products. BR Then see the bottom of the cooling fan, fan diagonal size of a large selection of products. Best use of magnetic levitation, Or nano-ceramic fan, if open, then push the fan blades by hand, press down to about 2mm is magnetic levitation, the contrary is not. Ask See whether it can confirm the type and cooling fan Such as the use of AVC and other international companies, and shows manufacturers are willing to invest the cost. Level will affect the cooling efficiency of the internal components of life, and good cooling fan will reduce the normal operation of the noise. BR Look at the power plug, three-pin plug should buy the product. Then enter the product . Product testing in five procedures: BR One, listen to the voice BR Power on boot, in addition to the normal fan of the sound, should not hear the other noise and current noise. BR 2, test button BR Individually test all the key functions is to operate correctly, out of key failure of the product. BR 3, test security BR no pot boil down to protect the work with the state to observe the induction cooker is automatically alarm, usually about 2 minutes will automatically cut off power supply. BR protection of air pot air pot slightly longer heating time, and some appliance will automatically send alarm and stop heating. Some of the appliance without this feature. BR improper heating in the furnace surface protection to try to place small items such as iron ladle and then boot, usually with an area of less than 65% of the pot could not be properly heated. If Taiwan Induction heating of small objects when the automatic alarm, automatic shutdown after 90 seconds. Some induction cooker does not this feature. BR Four adaptive test pot BR Ohmic heating process, repeated several times to take pot, place pot in action, to see whether the normal recovery time for heating, typically 1-3 seconds to take back into the pot will resume after the heating, if the recovery time is greater than 5 seconds shows that this machine on the pot with a good adaptability. BR 5, test temperature BR Check whether the appliance 100 temperature zone design, with matching pot boil water, to see after the water is set at 100 gear can maintain boiling. Design allowed the temperature will lead to burn-in risks, because many of the internal protection is based on temperature monitoring. In the water heating process, the pot can be moved to the edge 1 / 4 or 1 / 3, maintaining 1-2 minutes, should continue to heat, indicating normal function of the appliance heating. The choice, as selected temperature control block and more, in between 100 to 270 , if a 10 or 20 in an incremental, will be more convenient to use. BR Selection and testing in accordance with the above steps, I think you spend 10 minutes to buy the appliance can become an expert in! I am an expert from skf16.com, while we provides the quality product, such as Thrust Roller Bearing , China Taper Roller Bearing , Deep Groove Ball Bearing ,and more.
