Ignition lag time in the first reflection period (ionization time)
v/2
Velocity of propagation
Procedure
1. Press the CURSOR key.
2. Place the zero cursor on a peak of the trace (1).
3. Place another cursor on the next peak of the trace (2).
The fault distance including the length of the test lead is displayed (3).
4. Subtract the length of the test lead (10 m) from the displayed fault distance.
Recommendation: With long cables, place the each of the cursors on the rising flank.
Recommendation if the fault position is not easily visible
 If no breakdown was achieved or if the fault position is not visible properly in the reflection
image, increase the voltage (if permitted) and repeat the measurement.
