3.3.6.3 AIR PRESSURE submenu
An additional pressure test of the STIP-scan probe must be done upon first start-up. The probe
body of the STIP-scan analyzer is slightly pressurized with the air pump supplied in the accessory
kit.
Pressurize the system as follows:
1. Select AIR PRESSURE from the TEST menu. The following screen appears:
Fig. 3.3.6.3-1: Air pressure screen
2. Depressurize the STIP-scan probe and save the pressure shown in the “CURRENT“
field by pressing the “SAVE“ button. The current pressure is shown then in the “MEMO“
field.
3. Close the probe and connect the connection line to the probe. Make sure that the probe
is sealed.
4. Pump air into the probe to pressurize the probe the air pump supplied in the accessory
kit. You can follow the increasing pressure in the "CURRENT" field. Keep pumping until
the difference between the pressure inside the probe ("MEMO") and the ambient pressure ("CURRENT") is approx. 300 mbar.
5. Save the shown pressure (“CURRENT“ field) so that the value is shown in the “MEMO“
field.
6. Wait for 30 minutes. Then check if the pressure inside the probe is still constant. A maximum pressure droop of 20 mbar within 30 minutes is allowed.
7. If the proof pressure test can be performed successfully, depressurize the STIP-scan
probe, save the shown pressure (“CURRENT“ field) and restart the measurement
(menu START MEASUREMENT).
A pressure drop > 20 mbar may indicate a leak. Please contact your service technician
of Endress+Hauser Conducta GmbH&Co.KG Division STIP.

At each start-up of the STIP-scan software, a systems test is performed and displayed (see fig. 3.3.3.13, page 3-13 and fig. 3.3.6.4-1, page 3-43).
