High-precision clamp ammeter, also known as current recorder, clamp current recorder, card current recorder, etc., is mainly designed to facilitate high-precision measurement of on-site current usage status monitoring and recording. It uses large-capacity card storage to ensure uninterrupted monitoring. High precision, high stability and high reliability are composed of host, current clamp, communication line, current monitoring software, memory card, etc. It is widely used in electric power, communications, meteorology, railways, oil fields, construction, metrology, scientific research and teaching units, industrial and mining enterprises and other fields. The high-precision clamp ammeter has real-time clock, large-screen display, data export and other functions, which are convenient and easy to use. At the same time, the card has a large storage space that can store group data and also has an automatic storage interval setting function from ~ minutes.
The high-precision clamp ammeter monitoring software has online real-time monitoring and historical query functions, and has the functions of reading, reviewing, saving, analyzing, processing, sorting, reporting, and printing historical data.
