Evaluating Calculation Results on a Pass/Fail Basis
7.3 Evaluating Calculation Results on a Pass/Fail
Basis
You can specify evaluation criteria ([Up] and [Low]) to evaluate numerical calculation results on a
pass/fail basis.
Each numerical calculation can has different evaluation criteria.
The waveform acquisition process varies depending on the recording mode setting ([Single] or
[Repeat]) and the stop condition specied to stop the measurement depending on an evaluation
([PASS], [FAIL], or [PASS & FAIL]).

Click the [Judge stop condition] box, and then from the list, choose a stopping condition
applied according to judgments.
PASS Stops measurement when a calculation result falls within a criteria range (pass
judgment).
FAIL Stops measurement when a calculation result is outside a criteria range (fail judgment).
PASS & FAIL
Stops measurement regardless whether a pass or fail judgment is given.

Click the [Judge] box, and then from the list, choose whether or not to evaluate calculation
results.
Off
Evaluates calculation results.
On Yields a fail judgment if a result is outside a criteria range.
Calculated values in a channel with the fail judgment are highlighted in red.

Click the [Up] and [Low] boxes in turn, and then enter evaluation criteria values in each of
them.
Enterable range: −9.9999E+29 to −1.0000E29, 0, +1.0000E29 to +9.9999E-29
(To evaluate existing data)
Click [Execute].
(To automatically execute evaluation after measurement)
Click the start icon.
About upper and lower limit values
You cannot specify an upper limit value lower than a lower limit value.
Neither can you specify a lower limit value higher than a upper limit value.
To record all calculation results
Choose [PASS & FAIL] for the stopping condition.
