PRODUCT FEATURES
1. Exceptional discharge sound quality with quieter background, using monitoring headphones for fast and reliable fault point localization.
2. Selective recording of magnetic field signals for higher localization accuracy, with fully automatic triggering threshold settings for sound and magnetic field channels.
3. Adopts ultra-quiet technology and BNR intelligent background noise reduction, enabling on/off control of the impact discharge volume upper limit.
4. The black arrow on the receiver automatically indicates the advancing direction during precision localization, prompting return when passing the fault point.
5. The yellow arrow on the receiver simultaneously indicates the relative left/right position of the fault cable’s central axis, ensuring the probe stays directly above the cable.
6. Determines the precise fault location by comparing time differences between two consecutive impact discharge sounds.
7. Molded design of a special self-falling ground sensor, equipped with sensing adapters for soft pavement, hardened pavement, and lawns.
8. Uses reliable imported connectors to ensure sound purity, with a humanized adjustable probe handle for versatile applications.

FAQs
Q: How does BNR intelligent noise reduction work on the RDCD-III/R30 cable detector?
A: The RDCD-III/R30 adopts ultra-quiet technology and BNR intelligent background noise reduction, which suppresses interference and provides clearer discharge sound. It also supports on/off control of the 84dB(A) impact discharge volume upper limit for safer and more accurate fault localization.
Q: What ground surfaces are compatible with the RDCD-III/R30’s self-falling ground sensor?
A: The RDCD-III/R30 uses a special molded self-falling ground sensor with dedicated sensing adapters, making it suitable for soft pavement, hardened pavement, and lawns to ensure stable sensing in different on-site environments.
Q: What functions do the black and yellow arrows provide on the RDCD-III/R30 receiver?
A: The black arrow automatically shows the forward direction for precise fault location and alerts users when passing the fault point. The yellow arrow indicates the left/right position relative to the cable’s central axis, keeping the probe directly above the target cable.
Q: What filter modes are available on the RDCD-III/R30 and their frequency ranges?
A: The RDCD-III/R30 offers four filter options: no filter (100Hz–1500Hz), low-pass filter (100Hz–400Hz), band-pass filter (150Hz–600Hz), and high-pass filter (200Hz–1500Hz) to adapt to different on-site interference conditions.
Q: What main components and accessories compose the RDCD-III/R30 cable comprehensive detector?
A: The instrument includes a transmitter, transmitting current clamp, receiver, flexible receiving current clamp, and connection test cables. Optional accessories include a stethoscope and A-frame, supporting pipeline path detection, cable identification, and grounding fault location.
