External Control
Signals can be output when the results of evaluation of numerical calculations
are GO (pass) or NG (fail).
The default setting (factory default) is [Num Calc] .
Evaluation result output period (for numerical calculations: 100 ms or greater
For one-shot measurements, the signal is saved. It returns to HIGH on the next
start.
For continuous measurements, the signal is saved until the next trigger event
occurs.

14.2.5 GO/ NG Evaluation Output
(GO/EXT OUT1)/ (NG/EXT OUT2)
Evaluation result is
GO or NG
Signal is output.
GO/EXT OUT1
NG/EXT OUT2
The GO/EXT OUT1 and NG/EXT OUT2 terminals can be used as GO/NG evalu-
ation output terminals (GO, NG) or as external output terminals for specific con-
ditions (EXT OUT1, EXT OUT2) (p. 389). They cannot be used for both functions
at the same time.
