Test di certificazione per multimetri digitali

To use the multimeter safely, you must first select a digital multimeter that is suitable for the application and meets the application environment. Once you have selected the appropriate multimeter, you will use it in accordance with normal application procedures. The International Electrotechnical Association has set new standards for working under power systems. Make sure that the meter you are using meets the IEC standards and its voltage rating meets the field application requirements. For example, if you measure a 480V power panel, your meter should meet the CATIII_600V standard. This means that the input circuitry of this watch is designed to withstand transients in this application environment without harming the user. Choosing a watch marked with UL, CSA, CDE, TUV means that this watch not only meets IEC standards, but has been independently certified and tested and meets the independent testing agency's own standards.
