Extended Actuator Signature (Extended Act. Sig.)
The extended actuator signature slowly ramps the pressure to the actuator up and down over
a user-selected position range and measures the position vs. pressure. The signature is useful
for determining valve friction and for identifying performance problems at specific valve
positions. To perform this test:
1. Select Extended Act. Sig.
2. Adjust the Start Position, Stop Position and Speed Level parameters, if necessary.
3. Click Perform Diag.
