This guide describes how to install, configure, and use the SCXI-MS100
temperature measurement system.
The SCXI-MS100 is a complete virtual-instrument-based temperature and
voltage measurement system for Windows 2000/NT/98/95. The system
includes the software and hardware needed to acquire and log up to
32 channels of data without any programming. You can configure each
channel for thermocouple or voltage input, and add additional SCXI
modules to expand the number of channels to 128.
The SCXI-MS100 is ideal for multichannel temperature applications in
many environments, such as process monitoring, industrial automation, and
instrumentation. The SCXI-MS100 combines SCXI and data acquisition
(DAQ) products to take accurate temperature measurements with
thermocouples. Taking measurements with thermocouples requires
amplification, cold-junction compensation (CJC), and high-resolution
analog-to-digital converters (ADCs). In addition, the included
VirtualBench-Logger software is an interface you use to display and
log data.
To set up and use your SCXI-MS100 temperature measurement system,
you need the following:
