Measurement Computing DBK42 - Manual (Page 6)

Software Setup
You will need to set several parameters so DaqView can best meet your application requirements.
After the 5B module type is identified, DaqView figures out the m and b (of the mx+b equation) for proper
engineering units scaling. An example of the mx + b equation follows shortly.
The mx + b calculations for most 5B modules are included within LogView software.
Reference Note:
o For DaqView information refer to chapter 3, DBK Setup in DaqView and to the DaqView
PDF included on your data acquisition CD.
o For LogView information refer to chapter 4, DBK Setup in LogView and to the LogView
section of the LogBook PDF included on your data acquisition CD.
o The API includes functions applicable to the DBK42. Refer to related material in the
Programmer’s Manual (p/n 1008-0901) as needed.
PDF Note: During software installation, Adobe ® PDF versions of user manuals automatically install onto
your hard drive as a part of product support. The default location is in the Programs group,
which can be accessed from the Windows Desktop. Refer to the PDF documentation for
details regarding both hardware and software. Note that you can also access PDF documents
directly from the data acquisition CD via the button on the CD’s opening
screen.
mX +b, an Example
The Customize Engineering Units dialog box can be
accessed via the DaqView Configuration main
window by activating the Units cell [for the desired
channel], then clicking to select mX+b.
From the Customize Engineering Units dialog box
(see figure at right), you can enter values for m and b
components of the equation that will be applied to
the data. There is also an entry field that allows you
to enter a label for the new units that may result from
the mX+b calculation.
An example of mX + b equation use follows.
