| MEWOI7800E Clamp Meter is specially designed for measurement online of AC/DC leakage current with voltage below 600V; by adopting up-to-date CT technology and digital integration technology, There is not metallic conductor outside the clamps, non-contact test to ensure save. It is a product with relatively small size, large clamp, high accuracy and perfect function, widely applied in those fields as electricity, communications, meteorology, railroad, oilfield, construction, measurement, scientific & research teaching institutes, industrial and mining. It is essential tool for electrician safety testing. This High Accuracy Clamp Leaker have the function of peaking holding, data holding data storage; obtains one USB interface. With the help of the software that we provide, many functions are available. For example, the meter can realize on-line monitoring, historical data inquiry, active curve drawing, indication of max, min and average value and indication, alarm value setting, indication of alarm value, historical data inquiry, export, and print. |
