  • Page 21 ESD footwear and stepping onto a floor surface. The PGA-710 Autoanalysis System was originally designed primarily for ionization decay analysis. However, other decay analysis applications are apparent. The following illustrations focus on measuring decay time of a bench top ionizer. The principles apply to many other evaluations and measurements where the voltage change over time is an important measurement.
