Multimeter

A multimeter is a portable electronic testing instrument used to measure electrical parameters such as voltage, current, and resistance. In foreign trade, it falls under the category of electronic measuring instruments and is commonly used in fields like electrical work, electronic repair, and scientific research and education. Usage scenarios include: when exporting and declaring customs, its HS code must be clearly identified (usually 9030.31 or 9030.32), and attention must be paid to the safety certification requirements for measuring instruments in different countries or regions (such as CE, UL, RoHS, etc.). Precautions: Confirm whether the product has functions such as data logging, true RMS, and auto-ranging, as these affect price and classification; also distinguish multimeters from similar terms such as clamp meters, oscilloscopes, and insulation resistance testers to avoid confusion during customer inquiries. Compared with ordinary voltmeters, multimeters are more integrated and can measure multiple parameters. Foreign trade practitioners should be familiar with their technical parameters (such as accuracy, range, display digits) in order to quote accurately and respond to customer technical inquiries.
