This is a fully functional VI for AVL 415S variable sampling smoke meters. The VI provides the same capabilities as the AVL PUMA software. I use this VI as part of our engine testing software at Iowa State University.
The AVL 415S is described by AVL as “a filter-type smoke meter for measuring the soot content in the exhaust of diesel and GDI engines.” This VI uses VISA commands to control the device to do three pre-configured tasks (Reset, Purge and Measure), display measured values and internal status data, and provide an option for manual control.
Steps to Implement or Execute Code
Connect your AVL Smoke Meter and test the connection using a VISA Test Panel in Measurement & Automation Explorer.
Download the attached VI.
Open the block diagram and confirm that it references the appropriate VISA resource (see below).
Run the VI.
Use the Reset, Purge and Measure buttons to control the VI.
