Minimum Pressure
When configuring the Minimum Pressure for the PST you are configuring the minimum
amount of pressure required for the Partial Stroke Test. The pressure change value is in the
configured pressure units. The PST Pressure Change must be between -120.0 and 120.0 psi
(-828 and 828 kPa, -8.28 and 8.28 bar). If you set a value outside the range an error message
appears (Figure 254).

Maximum Time
The Max Time parameter is the maximum amount of time allowed for the PST. The value must
be between 5 and 300 seconds. If you set the Max Time for a value outside the range an error
message appears (Figure 255).

PST Speed
The PST Speed is defined in terms of % of the total PST travel per second. The range for PST
speed is 0.25% and 10% in units of % per second. If you set the value outside the range an
