1. Press
F4 More Cable
until the reflection is
displayed.
2. Use the up (
2
) and down (
8
) arrows keys to adjust
the waveform height.
3. Use the left (
4
) and right (
6
) arrows to move the
cursor to the beginning of the wet section (“A” on
the illustration below). This is the distance to the
water.
4. Use the left (
4
) and right (
6
) arrows to move the
cursor to the end of the wet section (“B” on the
illustration below).
“A” to “B” is the wet section.
Note: The distance from the front panel to the water
(A) is correct. The wet section distance (A to B) is not
correct because water changes the velocity of propaga-
tion (Vp). Subtract the dry section distance from the
cable map to obtain the wet distance. Or measure from
both ends of the cable to the wet section.
