4.2 System Performance Benchmark
Each application and system configuration is slightly different. System performance will
vary when you change setup parameters and if your horn or tips change, and can affect
the results of your process. Creating a benchmark of your setup and performance can be
useful at a later date in identifying a change in performance, and can also help in
recreating your exact setup.
The following steps are used to record acceptable system performance, and part
acceptance.
Use the following steps to create and record a benchmark for your exact setup.
NOTICE
Make copies of the following page and keep it on file for future reference.
