* Sets Function to VDC, Range to 24V, Rate set to 6rps.
* Display five measurements using a Message box.
***********************************************************************
* Make sure SM2060.lib is included in the libraries. For Microsoft

5.3 Visual Basic Front Panel Application
The Visual Basic front panel application, SM2064.EXE, is an interactive control panel for the SM2060 family of
DMMs. When it loads it will take a few seconds to initialize and self calibrate the hardware before the front panel is
displayed.
The push buttons labeled
V, I , etc. control the DMM function. As you push a function, the front panel application
will switch the DMM to the selected range and function. Autorange mode is selected by pushing the AutoRange
check box. The S-Cal box recalibrates the DMM, leaving the DMM in the same state prior to operation. (This is an
