7 Functions on the Graphical Display
7.5. Fast Transient
(Available on the 8000 Series).
A transient is the rapid change in voltage. A typical transient reaches its peak in 5µs and lasts 50µs.
The meter captures transients with optional hardware that samples 5 channels at up to 6Msp for
22ms or 1 Msps for 131 ms.
7.6. Subcycle Disturbance
A disturbance is the rapid change in voltage with a duration that can be as long as 1/4 cycle. The
meter captures disturbances as events, which records all voltage and current channels at 30.72
ksps for 1000 ms.
7.7. Locating Events
The Events Main Screen lists the number of Events, Triggers and Log Items. From this screen, the
user can highlight and select View Events, View Triggers, View Log Items or ITIC Curve.
•
When View Events is selected, the screen will update to list all date and time stamped
events that have occurred. If an event is highlight and select from the list, a new screen
will appear displaying detailed information about that event. Additional information can
be accessed by highlighting and selecting View Captured Parameters, View Trigger or
View Present Measurement.
