Abstract
A method is disclosed for acquisition and analysis of condition monitoring data. Alarm and alert limits are set to proper levels and information regarding the frequency and cause for alerts is collected. Analysis of the information may then be performed to provide a user with easily understandable representations of the system errors and suggested actions.

6. A method for assisting a user in analyzing condition monitoring information from at least one device, the method comprising the steps of:
-
collecting condition monitoring data from a monitored device, wherein the condition monitoring data includes a plurality of parameter measurements;
comparing the parameter measurements to at least one of alarm limits and alert limits to obtain comparative values;
normalizing the comparative values to create reliability values; and
determining a device reliability index. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method for assisting a user in analyzing condition monitoring information from at least one device, the method comprising the steps of:
-
collecting a plurality of samples of condition monitoring data over time, wherein the condition monitoring data includes a plurality of parameter measurements; and
displaying information for each parameter to a user comprising an overall average of the parameter measurements and averages of the parameter measurements for at least one period of time. - View Dependent Claims (14, 15)

16. A method for assisting a user in analyzing condition monitoring information from at least one device, the method comprising the steps of:
-
collecting a plurality of samples of condition monitoring data over time for at least one device, wherein the condition monitoring data includes a plurality of parameter measurements;
identifying the parameters at warning status for each sample, wherein a parameter is at warning status when the parameter measurement is the same as or greater than a predetermined warning limit, each parameter further having a distinct warning limit;
determining the mean time between warnings for the at least one device, wherein the mean time between warnings for the at least one device is the average amount of time between samples where at least one parameter is at warning status, determining a frequency of maintenance for the at least one device based on the mean time between warnings for the at least one device. - View Dependent Claims (17, 18, 19, 20, 21, 22)
