4.8.3.5.1 Calibration Degassing Pressure
Sensor PE for Machines at High
Altitudes of >1,000 m
For calibration point -400 mmHg/-530 mbar
If the Dialog machine is used at high altitudes (>1,000 m above sea level), an
offset of +75 mmHg/+100 mbar per 1000 m must be used for the calibration
of the degassing pressure sensor
PE .
Measurement unit mmHg
1,000 m altitude: –325 mmHg (–400 mmHg + 75 mmHg offset = –325 mmHg)
2,000 m altitude: –250 mmHg (–400 mmHg + 150 mmHg offset = –250 mmHg)
3,000 m altitude: –175 mmHg (–400 mmHg + 225 mmHg offset = –175 mmHg)
Measurement unit mbar
1,000 m altitude: –430 mbar (–530 mbar + 100 mbar offset = –430 mbar)
2,000 m altitude: –330 mbar (–530 mbar + 200 mbar offset = –330 mbar)
3,000 m altitude: –230 mbar (–530 mbar + 300 mbar offset = –230 mbar)
Example for Calibration at 1,000 m
Altitude
1. Clamp tubing at filter degassing pump FEP .
2. Clamp tubing between degassing bypass valve VEB and degassing
pressure sensor PE and pull off tubing from the degassing pressure sensor
PE .
3. Connect a manometer and a syringe to the PE sensor, using a Y-piece and
extra tubing.
PE Calibration Point -400 mmHg
–530 mbar
4. Press the Degassing Pressure PE key.
5. Use syringe and create a negative pressure, e.g. at 1,000 m altitude:
•
–325 mmHg
±
10 mmHg (-400 mmHg plus 75 mmHg/1,000 m)
•
-430 mbar
±
13 mbar (-530 mbar plus 100 mbar/1,000 m)
6. Press key.
7. Enter the stable reference value:
•
–325 mmHg
±
10 mmHg (-400 mmHg plus 75 mmHg/1,000 m)
•
–430 mbar
±
13 mbar (-530 mbar plus 100 mbar/1,000 m)
Wait until digits are stable.
8. Confirm with key.
PE Calibration Point 0 mmHg
0 mbar
11. Remove syringe (0 mmHg/0 mbar).
12. Press key.
13. Enter 0 mmHg/0 mbar.
Wait until digits are stable.
14. Confirm with key.
15. Confirm and store complete calibration procedure with key.
Note: The calibration data is saved only after the bit sequence 0-1-0 (for
detailed information see 4.8.3.1 General Calibration Information).
16. Remove calibration devices.
17. Reconnect tubings.
