The AT47AV series has been upgraded to the AT47AV series, as an iterative upgrade model of the same series. The instrument is controlled by a high-performance ARM9 microprocessor with real-time high-speed data acquisition. The newly upgraded full-mirror touch panel features Onmeas's 9th generation ATOS operating system, supporting Chinese and English interfaces, making operation intuitive, easier, and smarter.
The newly designed AT47AV series comes standard with 64G internal memory, mapped as a USB drive via communication. Using real-time FPGA circuits, it breaks through sampling rate limits. Combined with efficient, high-precision analog circuits, it achieves high-precision and ultra-high-speed sampling, with temperature measurement resolution improved to 0.01°C.The instrument channel isolation voltage is 350VDC, 230VAC (full digital and analog signal isolation), suitable for complex systems requiring simultaneous temperature and voltage monitoring, such as new energy and automation control fields.
The instrument has built-in LAN interface, RS232, USB-232, VCOM virtual serial port. The RS-232 and USB-232 interfacessupport Modbus (RTU) protocol, and the LAN port supports Modbus (TCP) protocol. The instrument can be controlled and data collected via computer, effectively used for remote control and data acquisition and analysis.
The instrument supports USB communication. Through the included computer software, data acquisition, analysis, and printing can be achieved. It supports USB disk storage for real-time storage of sampled data. Users can perform independent calibration for each channel.
