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).

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: 2 kPa ±0.05% of Q-RPT span or 1 kPa (0.15 psia), whichever is greater
Ultimate pressure
