Notes:
1.
Assumes 100 cc test volume and pressure steps no greater than 17 kPa (2.5 psi), uses on-board pump control.
2. Assumes 100 cc test volume and pressure steps no greater than 70 kPa (10 psi), using with external gas supply.
3. Assumes 50 cc test volume and pressure steps no greater than 700 kPa (100 psi), using with external gas supply.
4. Assumes 25 cc test volume and pressure steps no greater than 7 MPa (1,000 psi), uses with external gas supply.
5. Set times are typical and reflect time to ready indication using default control limits in dynamic control mode.
6. Times for sub-atmospheric set points assume that the temperature is below the boiling point for the target pressure of any
liquid in the UUT and CPS.
7. Negative gauge and vacuum pressure values assume the ambient atmospheric pressure is approximately 101 kPa
(14.7 psi) absolute.
