GD-2134E Cable Identifier (Model GD-2134E)
• Multiple detection modes: classic positioning mode, wire cruise mode, signal curve mode.
•Classic positioning mode: compass, direction and signal amplitude display, intuitive display of the left and right directions of the pipeline.
•Wire cruise mode: 360°all-round pipeline path indication, continuous display of depth, current and relative position of pipeline. The interface is simple and intuitive, and can be operated without experience.
•Signal curve mode: can display historical signal strength curves, and find the cable location by observing the changes in signal strength curves at different locations.
•Current direction determination (partial frequency), by calibrating the current direction, eliminating interference from adjacent lines and preventing tracking errors.
•Built-in sweep frequency test function, users can select the appropriate signal frequency for pipeline measurement through the sweep frequency results to avoid co-frequency interference.
•Fully digital high-precision sampling and processing: stable and reliable, ultra-high sensitivity, extremely narrow receiving passband, strong anti-interference ability, and can fully suppress the power frequency and harmonic interference of adjacent running cables and pipelines.
•Ground fault search (optional function): The transmitter transmits the positioning signal to the faulty cable. The A-frame (optional accessory) can be used to locate the ground fault location point of the pipeline, and the arrow indicates the positioning direction.
•Multiple detection frequencies: 12 active detection frequencies and 4 passive detection frequencies.
•Multiple signal output modes of the transmitter: direct connection output, clamp coupling output, radiation induction.
•Transmitter digital amplification power output, fully automatic impedance matching, and fully automatic protection.
•The instrument has a built-in high-brightness light under it for easy night operation.

|
True or False Tips |
Eliminate interference from adjacent cables. When measuring adjacent cables, the measurement of adjacent cables can be distinguished based on the different signal strengths and measured current phases of the adjacent cables. In the process of tracing the cables, observe the phase dial and pointer direction to distinguish the measured cable from the adjacent cables. |

Sound Indicator |

|
Anti-interference Ability |
Extremely narrow receiving frequency band, unique digital processing method, can fully suppress the power frequency and harmonic interference of adjacent running cables and pipelines |
|
Interference Distance |
When 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. The greater the power and the higher the frequency, the stronger the interference.
The minimum distance at which the receiver is not interfered by the transmitter often needs to be determined by experiment: Pipeline detection: 5m away for the coupling method and 20m away for the induction method can be confirmed as no interference Cable identification: 2~5m away for the coupling method can be confirmed as no interference |
|
Cable Identification |
Identification method: flexible clamp intelligent identification, stethoscope identification;
Number of calibrable cables: 1 to 10; Calibration value: The current percentage of the receiving signal and the transmitting signal is between 75% and 135% of the calibration value, which is one of the conditions for successful identification; Directionality: The transmitting clamp, the receiving clamp and the loading signal must be in the same direction, which is one of the conditions for successful identification. |
