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 % of AutoRanged span, but with AutoRanged span no lower than 30 % of Q-RPT span (10 % with BG15K and G15K).
5 ±0.008 % of reading from 30 % to 100 % of Q-RPT span. Below 30 %; ±0.0024 % of Q-RPT span.
6 ±0.01 % of reading from 30 % to 100 % of Q-RPT span. Below 30 %; ±0.0030 % of Q-RPT span.
7 ±0.005 % of reading from 30 % to 100 % of any AutoRanged span between 30 % and 100 % of maximum Q-RPT span. Below 30 %; ±0.0015 % of AutoRanged span, or 0.0005 % of Q-RPT span, whichever is greater.
8 ±0.008 % of reading from 30 % to 100 % of any AutoRanged span between 30 % and 100 % of maximum Q-RPT span. Below 30 %; ±0.0024 % of AutoRanged span, or 0.0007 % of Q-RPT span, whichever is greater.

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
