To display the recorded transients, press . The List of Searches for Transients screen is displayed.
Display of sub-mode used.
Memory indicator. The black bar
represents memory used; the white
bar represents memory available.

If the stop date is in red, it means that it does not match the stop date initially programmed:
either because of a power supply problem (battery low or disconnection of the device supplied by mains only),
or because the number of transients has been reached, thereby ending the search.
To select a search for transients, move the cursor to it using the and keys. The selected search is bolded. Then validate with
the
key. The device then displays a list of transients.
Location in the record of the zone
displayed.
Selection of curves to be displayed.
Instantaneous value of the signals
according to the position of the cur-
sor on the scale. To move the cursor
use the or key.
Move the cursor to one period of
the signal before the transient trig-
gering time.
Move the cursor to the transient
triggering time.
Reminder of the number assigned to
the curve displayed; here, identifica-
tion disc 1 is filled in to indicate that
channel V1 triggered capture of the
transient.

To select a transient, move the cursor to it using the and keys. The selected field is bolded. Then validate with the
key.
The device displays the transients in the form of curves.
The icon is used to activate or
deactivate the choice of a transient
list display filter.
Transients display filter:
∀: all transients are displayed.
3 V: the transients triggered by an
event in one of the 3 voltage chan-
nels are displayed.
3 A: the transients triggered by an
event in one of the 3 current chan-
nels are displayed.
L1, L2, or L3: the transients trig-
gered by an event on a particular
phase are displayed (voltage or
current).
Triggering channel of the transient.
Transient number.
Name of the search for transients.
