CHAPTER 3 Settings and Measurement
(3)-2 Stop side source setting
Specifies trigger conditions to stop data capture.
Selection item

(3)-3 Repeated capturing
Sets up the repeat function to conduct repeated capturing.
Selection item

On
(3)-4 Alarm level settings
Sets alarm generation conditions, output destination, etc.
When the conditions specified here are met, the alarm output terminal (for which an output
destination number must be specified for each channel) outputs an alarm.
Refer to page 3-31 for details on the condition setting for each channel.
(3)-5 Alarm hold
When "On" is selected here and once the conditions are met, an alarm is not canceled even if
the conditions are no longer met later (Press the CURSOR key to cancel it).
(3)-6 Send burnout alarm
When "On" is selected here, the generation of a burnout (refer to page 3-38) causes the alarm
output terminal to output an alarm.
3−30
Stops capturing data unconditionally when you press the Start/Stop key.
Stops capturing data when a specified level is reached.
-> When Level is selected, the condition for each channel must be set. Refer to page 3-31 for
details.
Stops capturing data when an alarm is generated in the specified alarm port.
Stops capturing data when an input signal is received from an external trigger terminal.
* A trigger is established at a transition from 5 V (open) to 0 V (shorted to the ground).
A falling edge operation occurs.
Stops capturing data when specified date and time arrives.
Stops capturing data at the specified time on days of week for which On is set.
Example: On is set for Mon, Tue, Wed, Thu, and Fri, Off is set for Sun and Sat, and 17:00 is set as the
time.
Starts capturing data at 17:00 on weekdays.
Stops capturing data when a specified length of time elapses.
• When External Input is used as the trigger source, no stop trigger is accepted for 50 ms after capture is
started.
• When the start trigger is External Input, data is captured at sampling intervals (fixed to 30 seconds if
they are more than 30 seconds) and retained temporarily.
This retained data is refreshed at sampling intervals (fixed to 30 seconds if they are more than 30
seconds).
Since the external trigger input operation conducts detection at 10 ms intervals asynchronously from
sampling, the retained data becomes the first point when an external trigger is detected. Starting from
this point, data is captured at sampling intervals.
• This retained data is refreshed at sampling intervals (fixed to 30 seconds if they are more than 30
seconds).
The repeat function is disabled.
The repeat function is enabled.After one capture is ended, the next capture is started (If the start
side source setting is not Off, the GL820 waits for a trigger).
