Instrumentation Laboratory Exercise 11
To fully utilize the capabilities of VEE programming you need to
master the various steps:
• Reading the input signal
• Signal processing (scaling, applying calibration factors, and so on)
• Displaying and saving the processed signal
Figure 1- 8 shows a brief example of the various program segments.
• The Direct I/O box (left) is required for reading of the input signal.
• The Formula box (center) is used for signal processing.
• The Alpha Numeric box (right) is to display the resulting data.
Notice that there are inputs and outputs (small black squares on the
left and right hand sides of the boxes) for each of the boxes. In
general the inputs are on the left and outputs are on the right, so the
program has a left- to- right flow.

Double- click the < Double-Click to Add Transaction >, and a menu will
appear. Key in the following commands one line at a time:
1 "ROUT:SCAN, (@101)" // Tells the DAQ to scan
channel 101 only
2 "SENS:VOLT:POL UNIP, (@101)" // Sets the input to
unipolar mode
3 "SENS:VOLT:STYP SING, (@101)" // Sets the channel to be
read relative to ground
4 "SENS:VOLT:RANG 10, (@101)" // Sets the channel to a
10 V maximum input
5 "MEAS:VOLT:DC? (@101)" // Requests a DC
measurement of voltage
