BeneVision N Series Patient Monitor Operator’s Manual 10 - 5
To initiate auto alarm limits, follow this procedure:
1. Access the Limits page in either of the following WAYS:
◆ Select the Alarm Setup quick key → select the Limits tab.
◆ Select the Main Menu quick key → from the Alarm column select Limits.
2. From the Limits page, select Auto Limits at the left bottom.
3. Select Ok from the popup dialog box.
Then the monitor will automatically calculate alarm limits basing on the latest measured values. Before applying
these automatically created alarm limits, confirm if they are appropriate for your patient from the Limits menu. If
not, you can adjust them manually. These alarm limits will remain unchanged until you select auto limits again or
adjust them manually.
The monitor calculates auto limits basing on the following rules:
