Check Details

The Check Details screen can be used to analyze all check item values within a check sheet.

Check Details

Select a Check Sheet using the Check Details button. You can filter the results for a specific asset and/or item and for a set date range. All check data can be displayed in the table or filtered by Check Group. The table view can be configured to show check items as columns or rows, depending on user preference. Displaying check items as columns is faster with large datasets and enables additional analytical measures, such as min, max, average, and standard deviation, that are not available when timestamps are shown as columns. Each timestamp represents an instance when the checks within a check sheet were performed.

The information displayed in the table can be further expanded by enabling the following checkboxes:

  • Show Summary - Display summary data (Sum, Avg, Min, Max, Range, Std Dev)
  • Show Group - Display Group info
  • Show Resources - Include resources as Item, Asset, Shift, etc.
  • Show Status - Include Check Sheet status
  • Show individual Measurements - Display individual measurements

Check Details Trend View​

You can trend any check item by selecting it in the table and clicking theCheck Details icon. The Trend View allows users to analyze data over time through time series or histograms. It also provides the functionality to apply Statistical Process Control (SPC) rules against collected data, helping users understand trends and identify patterns. The trend view can be viewed by selecting a data point and clicking the 'Trend View' button. Once inside, you can change the trended data point by selecting a different row in the table or using the tree selector.
