Digital Cable Fault Locator with Clamp Current Method and Self-discharge for Accurate Detection

Main unit panel

① High Voltage Output: Dedicated DC high voltage output terminal;

② Voltmeter: High voltage output voltage indicator (kV);

③ Ammeter: Output current indicator (mA);

④ Fuse Holder: Fuse mounting location for AC220V power supply system;

⑤ Power Socket: Instrument operating power supply, AC220V connection port;

⑥ Power Switch: "Position 1" uses AC220V power to supply the system; "Position 0" is off;

⑦ Positioning Mode Frequency Adjustment: Adjusts the pulse output frequency in positioning mode;

⑧ Voltage Adjustment: After starting the equipment, this knob must first be turned counterclockwise to the end. When the high voltage start button light illuminates, press the start button, and then adjust clockwise to adjust the output high voltage... Increase the voltage from small to large, and decrease the output high voltage from large to small by adjusting counterclockwise;

⑨ High Voltage Stop Button: When the test is completed or an abnormality occurs, press this button to cut off the high voltage output. The high voltage light will turn off, and the stop button light will illuminate to indicate high voltage output, and turn off to indicate no high voltage output;

⑩ High Voltage Start Button: When the start button light is on, it indicates that the voltage output is at zero. The start button is only effective when it is on. If the start button light is not on after turning on the power switch, adjust the voltage adjustment knob counterclockwise until the light illuminates. When the start button light illuminates, press this button to start the equipment and generate high voltage output;

⑪ Overcurrent Protection Switch: When the blue light is on, overcurrent protection is on; when the blue light is off, overcurrent protection is off.

⑫ Positioning/Withstand Voltage Function Switch: When the red light is on, it is in withstand voltage function; when the green light is on, it is in positioning function;

⑬ Grounding Post: Instrument grounding point for safety protection;
