Opening Previously Stored Transients
The screen below can be accessed with the retrieve button . It displays a list
transients previously stored in the memory.
The status bar at the top displays the memory filled by stored transients.
Name and transient number (from 01…50) for each stored transient.
Transient recording time and date are displayed for each transient.
– To select a transient, press the Up/Down Cursor buttons, then press
Enter.
– To delete a selected transient, press the Trash Can button , then press
Enter.
Storing the Trigger
The threshold T in percent, defined as an envelope width (over and under) the
last cycle of signal V or A input signal. Its width W is calculated with the nominal
measurement range R for a channel (depending on the selected current sensor).
W = T x R
Using the SR193 probe and a 2% trigger level, the width would
be 1000A x 2% = 20 A. Therefore, a deviation of ±20 A will
cause a transient event to be captured.
