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.
³Maximum 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.

Note: Technical note 8050TN11 provides a detailed description of PPC4 Q-RPT uncertainties.

Pressure Control Modes and Ready Indication
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)

Pressure Control Performance
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: ±0.05% of Q-RPT span or 1 kPa (0.15 psia), whichever is greater
Ultimate pressure (absolute, negative gauge)	With low ultimate pressure option: 50 Pa (0.5 mbar, 0.007 psia) typical, depending on vacuum pump and connections Without low ultimate pressure option: 200 to 700 Pa (2 to 7 mbar, 0.03 to 0.1 psia) depending on vacuum pump and connections
Typical pressure setting ready time (0.005 % hold limit, 50 cc test volume)	15 to 35 s
