- 4-wire, 3-wire, or 2-wire PT100, PT500, and PT1000 RTDs supported
Software Features:
- QuickDAQ — Acquire and display from all Data Translation USB and Ethernet devices that support analog input streaming. Acquire data, record data to disk, display the results in both a plot and digital display, and read a recorded data file. Two additional options can be purchased to add FFT analysis capabilities to the base package. Also, data can be exported to other applications like Microsoft Excel® and MATLAB® for more advanced analysis
- IVI-COM driver — works in any development environment that supports COM programming, including Visual Basic®, Visual C#® .NET, MATLAB®, VEE Pro, LabVIEW™ or LabWindow, and others
- SCPI support — SCPI (Standard Commands for Programmable Instruments) is a universal programming language for electronic test and measurement instruments, based on the IEEE 488.1 and IEEE 488.2 standards
