Pressure control

Control Modes

Dynamic (standard and high volume):  Sets target within hold limit and continuously adjusts pressure to remain at target value.

Static: Sets target within hold limit and stops control, allowing pressure to stabilize naturally.

Monotonic:  Sets pressure to target and maintains very slow ramp in same direction as pressure increment.

Ramp: Sets and maintains user specified rate of change of pressure.

Piston Gauge Control : Automates piston gauge pressure control.

Control Precision To ± 0.001 % of Q-RPT span (standard dynamic)
Control Volume 0 to 100 cc, 50 cc optimum (operates in larger volumes but pressure stabilizing time increases)
Slew rate 60 sec. 0 to full scale, 50 cc volume

  1. Combined linearity, hysteresis and repeatability.
  2. Predicted Q-RPT measurement stability limit (k=2) over one year assuming regular use of AutoZero function. AutoZero occurs automatically in gauge mode whenever vented, by comparison with barometric reference in absolute mode. Absolute mode predicted one year stability without AutoZ is ± (0.005 % Q-RPT span + 0.005 % of reading).
  3. Maximum deviation of the Q-RPT indication from the true value of applied pressure including precision, predicted one year stability, temperature effect and calibration  ncertainty, combined and expanded (k=2) following the ISO "Guide to the Expression of Uncertainty in Measurement."
  4. Maximum deviation of the PPCH-G controlled pressure from the true value including measurement uncertainty and standard dynamic mode control hold limit.
  5. % of reading applies to 30 to 100 % of Q-RPT span. Under 30 % of Q-RPT span, uncertainty is a constant value obtained by multiplying the % of reading value by 30 % of Q-RPT span.
  6. % of reading value times measured pressure from 100 to 30 % of AutoRanged span. Under 30% of AutoRanged span, % of reading value times 30% of AutoRanged span. If AutoRanged span is less then 30% of maximum Q-RPT span, % of reading values times measured pressure, or % of reading times 9% of Q-RPT span, whichever is greater.
