Automated Pressure Calibrator

CPC 6000

44 Mensor/WIKA Operating Instructions - CPC 6000

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.
