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

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
EXAMPLE 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.
