Setting Interference Rejection for a Distance to Fault Measurement

---

Other signals can interfere with distance to fault measurements. When making a distance to fault measurement in the presence of known or suspected interference, you can minimize the effect of the interference on the measurement by activating interference rejection in the test set.

---

NOTE:

Use of interference rejection will increase the measurement time. Interference rejection should be used if a known interfering signal exists or if the distance to fault measurement displays suspicious characteristics such as a spike or rapid movements in the noise floor.
