3 terminology and units of measurement

3.1 Terms 3.1.1 gauge (vacuumgauge) [GB/T 3163-2007 4.1.2 Definition] An instrument measuring the gas pressure below atmospheric pressure or steam pressure. 3.1.2 Capacitance Diaphragm Gauge (capacitancediaphragmvacuumgauge) Displacement of the diaphragm by utilizing pressure differences, resulting in capacitance between the diaphragm and the fixed electrode is changed, by measuring This amount of capacitance change to measure the pressure gauge. 3.1.3 calibration chamber (calibrationchamber) To standard gauge and the instrument to be calibrated to provide a common vacuum chamber vacuum medium. 3.1.4 The bottom pressure (basepressure) [ISO 3567.2011 (E) defined 3.17] Before entering the calibration chamber calibration gas, calibration or backward valve off after some time, the calibration chamber pressure. NOTE. Do not base pressure and the residual pressure (residualpressure) confused, the latter refers to the indoor calibration can achieve a minimum pressure Force, usually baking results degassing or after prolonged pumping. The bottom pressure may be higher but not lower than the residual pressure.
