Overview
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.
Description
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.
