Function and system design
Measuring principle
Electronic acquisition, display, recording, analysis, remote transmission and archiving of analog and digital
input signals.
Measuring system
Multi-channel data recording system with multi-coloured LCD display (120 mm / 4.7" screen size),
galvanically isolated universal inputs (U, I, TC, RTD), digital input, transmitter power supply, limit relay,
communication interfaces (USB, Ethernet, RS232/485), internal Flash memory and CompactFlash card. 100
ms scan rate for all channels. ReadWin
®
2000 PC software for comprehensive offline device configuration and
data analysis.
