5.1.5 Calibrating the Vacuum Degas Assembly
When to Calibrate
•
After every 6 months of use
1. Open the ICS-2100 Wellness Panel in Chromeleon (see
Section 5.1.1 ), or open the ICS-2100 touch screen PUMP DEGAS page
(see Figure 5-6 ).
2. On the Wellness Panel under Degas Calibration, select Calibrate, or
touch Calibrate on the ICS-2100 touch screen. The degas pump runs
for 90 seconds to allow a vacuum to be created. After 90 seconds, the
vacuum degas pressure reading is recorded. When the vacuum degas
assembly is running in monitor mode, this calibration value is used to
determine when to turn on the degas pump.
3. If you are using the Wellness panel, click Log to record the new
calibration value in the Audit Trail.
4. If you performed the calibration from the ICS-2100 touch screen,
record the new calibration values in the Chromeleon Wellness
database. To do this, open the Wellness Panel (see
Section 5.1.1 ) and
click Upload under Update Wellness Database.
