Step Description
6
Select
to discharge the capacitor (only if
Measurement Start
option is set to
Manual
. See page 18.
Result:
A capacitor discharge (shot) is initiated.
If a breakdown / flashover takes place, the red fault trace typically has a strong negative
reflection. The red fault marker is automatically set to the position where both traces
diverge from each other.
NOTE:
If no trigger is received, no fault trace (red) is shown. Repeat the
procedure with a higher surge voltage (if possible) by selecting the
menu item.
If the blue trace (TDR trace) and the red trace are either 100%
matching or following each other very closely, the trigger has been
activated, however no breakdown/flashover was detected - increase
(
) voltage or possibly good cable.

If necessary, adjust the display settings, TDR settings and marker position through the
menu in order to identify the fault distance as precisely as possible. See page 38.

Select
to proceed with pinpointing or
to return to the main menu.
