Accessing a Statistical Report

To obtain a Statistical Report you need to specify the time period that the report is to cover. This is

accomplished as follows:

1. From the Gauge Window’s Display pull-down menu, select Statistical. The History Data window

will open (see following figure).

2. Drag the pointers across the slide scales to select the Start Date/Time, and the End Date/Time, which

is to define the period of time that the report is to cover.

3. Click the <OK> button to display the report.

4. To save the Statistical Report as an ASCII text file, select Save the Report from the Statistical

Report’s File pull-down menu (see following figure).

With options to “Save the Report” and to “Generate Limits”

Statistical reports can be used to automatically generate limit values based on historical data. If your

monitored machine has been operating at a steady state condition and if you have stored data at this

condition, then eZ-TOMAS can use this data to determine limit values based on the average and variance

of the data. However, you probably will want to edit these limits if the machine is experiencing amplitude

or frequency shifts.
