Figure 2–13: Ohms-at-Cursor Beyond Reflected Pulse
If the cursor is placed too near a fault, the reflection will not have stabilized,
which will make the ohms-at-cursor reading misleading. This is especially true
very near the instrument where some aberrations are still significant. See the
Ohms-at-Cursor section of the Operating Instructions chapter for more on the
limitations of this feature.
