Valves 3 And P1 Through P6; Valves Ps, 5, And 7 - Micromeritics ASAP 2020 Confirm Operator's Manual

ASAP 2020 Confirm

Valves 3 and P1 through P6

1. Open the regulator outlet valve for the gas connected to port 3.
2. Take a pressure reading; record it as P1 for valve 3.
3. Wait 10 minutes and take another pressure reading; record it as P2 for valve 3.
4. Subtract P1 from P2 and divide the difference by 10; record this value as the outgassing
rate for Valve 3. This value should be less than 0.7 mHg/min.
5. Repeat Steps 1 through 4 for valves P1 through P6 to which a gas is attached. Record the
values on the Valve Test Data Worksheet in the spaces provided.

Valves PS, 5, and 7

1. Close valve PS.
2. Open valve P1 for 60 seconds, then close it.
3. Take a pressure reading; store it as P1 for valve PS.
4. Wait 10 minutes and take another pressure reading; record it as P2 for valve PS.
5. Subtract P1 from P2 and divide the difference by 10; record the value as the outgassing
rate for Valve PS. This value should be less than 0.7 mHg/min.
6. Close valve 5 (close Valve 4 if open).
7. Open valve PS.
8. Open valve P1 for 30 seconds, then close it.
9. Take a pressure reading; record it as P1 for valve 5.
10. Wait 10 minutes and take another pressure reading; record it as P2 for valve 5.
11. Subtract P1 from P2 and divide the difference by 10.; record this value as the outgassing
rate for Valve 5. This value should be less than 0.7 mHg/min.
12. Close valve 7; open valve 5.
13. Open valve P1 for 30 seconds, then close it.
14. Take a pressure reading; record it as P1 for valve 7.
15. Wait 10 minutes and take another pressure reading; record it as P2 for valve 7.
16. Subtract P1 from P2 and divide the difference by 10; record this value as the outgassing
rate for Valve 7. This value should be less than 0.5 mHg/min.
