Pressure control. Modes and Ready Indication
HI Q-RPT span: 0-2 MPa [0-300 psi]	Static mode:  Sets pressure to target within hold limit and shuts off control in a closed test volume. Pressure is “ready” when inside hold limit and stability test is met. Dynamic mode:   Sets pressure within hold limit and continuously adjusts pressure to remain at target value. Pressure is “ready” when inside hold limit. Control parameters:   Hold limit, stability limit (default values can be adjusted by user) Control precision:   ± 4 ppm of Q-RPT span or ± 0.4 ppm of HI          Q-RPT span, whichever is greater. Lowest controllable pressure in dynamic mode:   Gauge: Zero set by automated venting. Lowest point above or below zero limited only by Q-RPT resolution and control precision.  Absolute, negative gauge: 2 kPa Ultimate pressure (absolute, negative gauge):   Typically < 50 Pa (0.008 psi) absolute depending on vacuum source and test volume configuration. Typical pressure setting ready time (0.005 % hold limit, optimum volume)   15 to 35 s Slew time (ATM to FS with 50 cc test volume):   30 s Typical test volume:   0 to 1,000 cc
HI Q-RPT span: 3.5-14 MPa [500-2,000 psi]	Static mode:  Sets pressure to target within hold limit and shuts off control in a closed test volume. Pressure is “ready” when inside hold limit and stability test is met. Dynamic mode:   Sets pressure within hold limit and continuously adjusts pressure to remain at target value. Pressure is “ready” when inside hold limit. Control parameters:   Hold limit, stability limit (default values can be adjusted by user) Control precision:   ± 4 ppm of Q-RPT span or ± 0.4 ppm of HI Q-RPT span, whichever is greater. Lowest controllable pressure in dynamic mode:   Gauge: Zero set by automated venting. Lowest point above or below zero limited only by Q-RPT resolution and control precision.  Absolute, negative gauge: 3 kPa Ultimate pressure (absolute, negative gauge):   Typically < 50 Pa (0.008 psi) absolute depending on vacuum source and test volume configuration. Typical pressure setting ready time (0.005 % hold limit, optimum volume)   15 to 35 s Slew time (ATM to FS with 50 cc test volume):   25 s Typical test volume:   0 to 500 cc

1. 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).
2. Combined linearity, hysteresis, repeatability. Add + 1 Pa (0.00015 psi) in gauge mode with an Axxx (absolute) Q-RPT for the resolution and short term stability of the on-board barometer.
3. Maximum deviation of the Q-RPT indication from the true value of applied pressure including precision, predicted one year stability limit, temperature effect and calibration uncertainty, combined and expanded (k=2) following the ISO “Guide to the Expression of Uncertainty in Measurement.”
4. Maximum deviation of the PPC4 controlled pressure from the true value including measurement uncertainty and default dynamic control hold limit.
5. % of AutoRanged span, but with AutoRanged span no lower than 30% of Q-RPT span (10% with BG15K and G15K). For example, if the Q-RPT is a Full Scale Standard A160K, the Measurement Uncertainty in pressure is 0.015% times the AutoRanged span for any AutoRanged span from 160 kPa to 48 kPa (160 kPa span x 30%) and 7.2 Pa (160 kPa span x 30% x 0.015%) for any AutoRanged span less than 48 kPa.
6. % of reading value times measured pressure from 100 to 30 % of Q-RPT span. Under 30 % of Q-RPT span, % of reading value times 30 % of Q-RPT span. For example, if the Q-RPT is a Standard A160K, the Measurement Uncertainty in pressure is 0.010% times the measured pressure to 48 kPa (160 kPa span x 30%) and 0.0048 kPa (160 kPa span x 30% x 0.01%) under 48 kPa.
7. % 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. For example, if the Q-RPT is a Premium A160K and AutoRanged span is 160 kPa, the Measurement Uncertainty in pressure is measured pressure x 0.008% to 48 kPa (160 kPa AutoRanged span x 30%) and 0.0038 kPa (160 kPa span x 30% x 0.008%) under 48 kPa. If the AutoRanged span is 100 kPa (greater than 30% of 160 kPa maximum Q-RPT span), the measurement uncertainty in pressure is measured pressure x 0.008% to 30 kPa (100 kPa AutoRanged span x 30%) and 0.0024 kPa (100 kPa span x 30% x 0.008%) under
30 kPa. If the AutoRanged span is 30 kPa (less than 30% of the 160 kPa maximum Q-RPT span), the measurement uncertainty in pressure is measured pressure x 0.008% to 14.4 kPa (160 kPa maximum Q-RPT span x 9%) and 0.0012 kPa (160 kPa maximum Q-RPT span x 9% x 0.008%) under 14.4 kPa.
