PST Diagnostics
One of the important safety features of the SVI II ESD is the ability to test functionality of the
instrument. In addition to running a Partial Stroke Test (PST), the ESDVue provides advanced
diagnostic capabilities and allows you to test the SVI II ESD terminal board and pneumatics
and to run extended testing on the actuator. The diagnostics area of the PST screen provides
access to all the diagnostic testing, shows the results from current testing and allows you to
load and view historical data.
