Automated Measurement Parameters for Statistical Processing
Items of statistical processing per period are given in section 9.2. Items of other
statistical processing are indicated in section 9.2 and 9.4. The result of statistical
processing that can be displayed is only two parameters of automated measurement.
Measurement Range during Statistical Processing
The measurement range is the same as that specified for normal automated
measurement (see section 9.2 and 9.4).
Show Results
If you perform statistical processing for each period or statistical processing of historical
data, a list of measured results can be displayed for the selected automated
measurement parameters.
The waveforms are numbered from the oldest historical data, and the corresponding
results of automated measurement are displayed.
The maximum and minimum values of each waveform parameter are displayed with the
↑ (maximum) and ↓ (minimum) symbols. If there are multiple points that are of the same
value, the maximum and minimum values are marked on the oldest data.
The number of data points that can be listed is 32000. If this value is exceeded, the
most recent 32000 points of automated measurement parameters of historical
waveforms or data are displayed. In this case, the maximum and minimum values may
exist outside the displayed list. In such cases, the maximum ↑ and minimum ↓ values
outside the range are not displayed.
In the list of statistical processing of historical data, you can select a waveform using the
jog shuttle and press SELECT to display the selected historical waveform.
For the statistical processing per period, statistical processing is performed only on the
data that can be listed.
In the list displaying the first-cycle statistical processing results, use the jog shuttle to
select a cycle number and press SELECT to zoom the waveform of the selected cycle.
Notes when Performing Statistical Processing
All soft keys except the Measure Abort soft key are disabled while the statistical
processing is in progress.
When loading waveform data of the maximum record length, statistical processing
cannot be performed on calculated waveforms. ***** is displayed for the measured
results.
Note
When performing statistical processing for each cycle, the completed percentage is
displayed.
