When measuring adjacent cables, the measurement of adjacent cables can be distinguished based on the different signal strengths and measured current phases fed back by the adjacent cables. In the process of tracing the cables, observe the phase dial and pointer pointing to distinguish the measured cable from the adjacent cables.Sound InstructionsFM tone that varies with signal strengthAnti-interference displayGreen: No interference Green: Good (results can be trusted) Red: Severe interference (results cannot be trusted)Anti-interference abilityThe extremely narrow receiving frequency band and unique digital processing method can fully suppress the power frequency and harmonic interference of nearby running cables and pipelines.Interference distanceWhen using the coupling method and the induction method, the transmitter will generate interference within a short distance. The interference distance is related to the transmission power and frequency.
