3-2. Stop side source setting
This is used to specify trigger conditions to stop data capture.
Selection item Description
Off Stops capturing data unconditionally when you press the [START/STOP] key.
Level Stops capturing data when a specified level is reached.
-> When Level is selected, the condition for each channel must be set.
Refer to "Trigger Level Settings/Alarm Level Settings" described below.
Alarm Stops capturing data when an alarm is generated in the specified alarm port.
External Input 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.
Date Stops capturing data when specified date and time arrives.
Weekly Stops capturing data at the specified time on days of the 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 9:00 is set as the time.
Stop capturing data at 9:00 on weekdays. Does not stop capturing data on Sat and Sun.
Time 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.
•
Even when the stop trigger is sent from an external device, the detection is executed in 10 ms. The data capture is
stopped when the stop trigger is received.
3-3. Repeated capturing
This is used to enable or disable the repeat function to conduct repeated capturing.
Selection item Description
Off The repeat function is disabled.
On 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 GL860
waits for a trigger).
When setting to the specified time, the date and time must be set. However, when the repeat function is
enabled (On), the specified time is changed to the time display. It occurs the trigger once a day.
