Setting value
[Factory default]
The output is turned ON if the judgement is OK.
On at OK For the overall judgement, the output is turned ON if all judgements
are OK.
The output is turned ON if the judgement is NG.
[On at NG] For the overall judgement, the output is turned ON if even one judge-
ments is NG.
Method to output measurement results without synchronizing with
[None] external devices.
Reference:
Method to output measurement results while synchronizing with exter-
Handshaking nal devices.
Reference:
Method to output measurement results while synchronizing with line
processing timing. The STEP signal is ignored the number of times set
Synchronization in [Number of delay], and measurement results are output when the
output STEP signal next turns ON. If through images are displayed, however,
synchronization output cannot be used.
Reference:
Valid only when [Output control] is set to [None].
Set the cycle by which measurement results are output. Set the cycle
2.0 to 5000.0 ms so that the interval is equal to or longer than [Gate ON delay + Output
[10.0 ms] time] and shorter than measurement interval. If the cycle is longer than
the measurement interval, output timing will be delayed while mea-
surement is being repeated.
Set the time from when results are output to the parallel interface to
1.0 to 1000.0 ms when the GATE signal turns ON. Waiting time until data output is sta-
[1.0 ms] ble.
Set this so that it is longer than the external device delay time.
This setting is enabled only when the [Output control] parameter is set
to [None] or [Synchronized output].
1.0 to 1000.0 ms
Set the GATE signal ON time.
[5.0 ms]
Set the time required for external devices to acquire measurement
results.
• If handshaking is used for output control, a timeout error will occur if
there is no response from the external device within the set timeout
interval.
• When the DSA signal turns ON after measurements are completed
0.5 to 120.0 s • When the DSA signal turns OFF after the GATE signal turns ON
[10.0 s] • When the DSA signal turns ON after the GATE signal turns OFF
• When using signals DI0 to DI6 and DI7 to execute a command, a
timeout error will occur if the time from when the ACK signal turns
ON until the DI7 signal turns OFF exceeds the set timeout interval.
(FH only)
This setting is enabled only when the [Output control] parameter is set
1 to 15 to [Synchronized output].
[1] Set the number of times that the STEP signal turning ON will be
ignored before measurement results of the STEP signal are output.
