Question: How does the cable identifier identify live cables? Answer: Connect the output coupling clamps according to the color respectively. The transmission host uses 220V or 4 AA alkaline batteries, and the output caliper is glued to the cable for identification in the direction of pliers identification. Cable Identifier On Problems: How Does a Cable Identifier Identify Live Cables? Answer: Connect the output coupling clamps according to the color respectively.
The transmission host uses 220V or 4 AA alkaline batteries, and the output caliper is glued to the cable for identification in the direction of pliers identification. After the cable identification instrument is powered on, the power indicator of the host is on, and the output indicator flashes to output, indicating that the output signal of the transmitting host is normal. At this time, the receiving flexible coil is about 3 meters away from the transmission jig and is also glued to the cable, and the sensitivity is adjusted.
The receiving box will display the corresponding attenuation waveform and direction arrow indication; the setting remains unchanged, other cables should display no such waveform. The magnitude and direction will be different. Note: The receiver's“O”The position turns black to indicate that a signal is received, the cable identification instrument receiver buzzer will sound once, and the number displayed in the middle will change.
If the signal is valid, the corresponding directional arrow will be displayed. If the arrow position is displayed continuously“X”or not triggered, it means that the amplitude is too small and needs to be adjusted. When the battery voltage is lower than 2.6V, it will display“undervoltage”, prompts you to replace the battery.
If the signal is received continuously and irregularly, there is interference and the reception range must be reduced or the reception location changed. The setting remains unchanged, the receiving coil and the receiving box are moved to other positions of the cable, the same cable is in the same direction as the initial waveform, and the amplitude is similar. Cable identification instruments are used to identify live cables.
The process is relatively simple. Power workers need to acquire skills and methods. At the same time, when identifying live cables, attention must be paid to their own safety.
