Rate: A rate (slewing speed) which best suits the user’s test requirements are selected here. The rates
vary the pressure slew rate while driving to a pressure setpoint. The [Slow] rate will target approxi-
mately .1% of the highest installed range/second. The [Medium] rate will target approximately 1% of
the highest installed range/second. The [Fast] rate will target approximately 10% of the highest in-
stalled range/second.
Variable rate allows the customer to enter the desired rate that the controller will approximate in the
current units/second.
Low Overshoot check: If this is checked, the control channel will minimize pressure overshoot when
driving to a new control setpoint.
Reference Vacuum check: ONLY AVAILABLE ON GAUGE UNITS! If checked, customers may pump
the reference port to achieve absolute emulation.
[Precision] key: If this key is selected, parameters are loaded into the active channel so that it will
operate with minimum overshoot and maximum stability. This changes the control stable window to
0.003% of the active sensor turndown and the stable delay to 4 seconds.
High Speed] key: If this key is selected, parameters are loaded into the active channel so that it will
operate in a high control speed mode. This changes the control stable window to 0.006% of the active
sensor turndown and the stable delay to 1 second. It also changes the way the controlled pressure ap-
proaches the setpoint to minimize the time to stable.
[Test] key: This key is used to enter a test mode that gives the user individual control of all solenoids.
This is further described in
Section 9 , Maintenance.
[Tune] key: This key is used to tune the regulator. This is described further in Section 9 , Maintenance.
