9.3 Judging Calculation Results
218
Set the judgment criteria (upper and lower threshold values) by which to judge numerical calculation
results. Judgment criteria can be set for every numerical calculation.
Waveform acquisition processing depends on the trigger mode setting (Single or
Repeat) and the criteria specified to stop measuring upon judgment (GO, NG or
GO & NG).

Procedure
To open the screen: Right-click and select [STATUS] [Num Calc] sheet
1
Make calculation settings. (p.214)
2
Enable the judgment function.
Move the flashing cursor to the [Judge] setting for Calcula-
tion No. to judge, and select [On].
Select
3
Specify the judgment thresholds.
Move the flashing cursor to the [ Lower] and [Upper] items.
Select an entry method and enter the threshold values.
Input range:-9.9999E+29 to +9.9999E+29
See: "7.1.3 Alphanumeric Input" (p.141)
4
Select the Stop Criteria upon judgment.
Move the flashing cursor to the [Stop Mode] item.
Select
Execute the calculations.
Applying Calculations to Existing Data
Select [Exec].
When judging automatically after measurement
Click [START] to start measurement.
Off Judgment is not carried out.
On
Result will be NG (Fail) if judgment range is exceeded.
Any channel in which result was NG is shown in red.
GO Continue to the next process when within the threshold range
(PASS judgment)
NG
Continue to the next process when outside of the threshold
range (FAIL judgment)
GO&NG
Continue to the next process regardless of judgment result.

About upper and lower threshold
The upper threshold of the period range cannot be set below the lower threshold,
and vice-versa.
About executing the calculation
Processing depends on the Trigger Mode setting.
If calculating while acquiring waveforms, measurement is repeated until the Stop
Criteria are met. (p.218)
To record all calculation results
Set the Stop Mode item to [GO&NG].
9.3 Judging Calculation Results
220
Judgment results of numerical calculations are displayed on the Waveform screen.
Within the judgment threshold range: GO judgment
Out of the judgment threshold range: NG judgment (displayed in red)
When the judgment result is GO
• The GO signal is output at the GO
/EXT.OUT.1 external I/O terminal. (MR8741
only)
When the judgment result is NG
• The NG signal is output at the NG
/EXT.OUT.2 external I/O terminal.
(MR8741 only) The NG judgment is asserted when any channel is judged as
NG.
• When the beeper is enabled, a beep sounds when a result is out of the thresh-
old range.
