Trigger Type
The Trigger Type tells the Product when and how to start and stop a scan. There are four
trigger types:
Note
If a Scan Count of 0 is set or if the scan interval is shorter than the scan
sweep time, the scan continuously repeats until the scan is stopped or the
Product runs out of memory.
•
The
Interval
trigger type sets the scan to happen on a user-defined numeric interval
that is started by a front-panel softkey in the Scan/Monitor menu. The user sets the
number of times to scan (Scan Count) and how often the scans occur (Interval).
•
The
External
trigger type sets the scan to start when a set TRIG input on the Digital
I/O port detects a low condition. Like Interval, the user manually sets the number of
times to scan (Scan Count) and the time between the scans (Interval).
•
The
Alarm
trigger type sets the scan to start when a HI or LO channel alarm is tripped
on a monitored channel. Like Interval, the user manually sets the number of times to
scan (Scan Count) and the time between the scans (Interval).
•
The
Manual
trigger type sets the scan to happen only when the user manually pushes
the Scan/Monitor key on the front panel. This trigger type lets the user set the number
of times to scan (Scan Count) when the key is pushed, but does not have an interval
time because the interval is a manual key push.
•
The
Automated Test
trigger type lets the user define a test sequence to run without
the need of user interaction. See “Automated Test” on page 4-16 for more
information.
