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 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.
