Programming the VT1422A & VT1529A/B
for Remote Strain Measurement
About This Chapter
This chapter describes using the VT1422A in combination with the
VT1539A Remote Channel SCP and VT1529A/B Remote Strain
Conditioning Units to make large channel count strain measurements. The
system is shown being used strictly in a data acquisition mode where, after
configuration, it is driven by a user-defined channel list (the Scan List) and
sends the measurements to the unit’s FIFO buffer and Current Value Table
(CVT) for transfer to the computer. Of course, control algorithms can also
be created that execute concurrently with the Scan List driven data
acquisition operation. Chapter 4 and Chapter 6 cover general data
acquisition and control programming with algorithms. This chapter assumes
that the user is an expert when it comes to making strain measurements, so
this chapter simply illustrates how to make strain measurements with the
VXI Technology Remote Strain Measuring System (VT1422A, VT1539A,
and VT1529A/B). The chapter will cover:
