Leakage detection rod

Leakage detection rodIt is a portable safety detection device designed based on the principle of electromagnetic induction, mainly used for quickly locating the location of leakage and preventing electric shock accidents. It is suitable for natural disaster rescue, industrial sites, building maintenance and other scenarios. By using the principle of electromagnetic induction, AC leakage current within a safe distance can be detected without direct contact with power sources or circuits, avoiding the risk of electric shock. For example, it can detect the leakage situation of 120/240 volt lines 5 meters away, or traditional unshielded transmission lines at a height of 150 meters. When approaching a power leak, the device will emit a buzzing sound and flash the LED light, and the alarm intensity will increase as the distance decreases. For example, in high sensitivity mode, the "beep" sound should be heard at least once every two seconds; The low sensitivity mode is used to accurately locate the leakage power source. Provide three modes of high, low sensitivity, and front focused detection (fine-tuning) to adapt to different scene requirements. For example, high sensitivity is used for preliminary scanning of large areas, while low sensitivity is used for narrowing down the range and confirming specific locations.

3、 Usage:

The arm passes through the smooth strap of the detector, and the red striped area is the sensing part.

Turn on the device: Rotate the mode switch ring and adjust it to the high sensitivity level.

Self testing: After adjusting to high sensitivity mode, wait for the self-test cycle to end (at least three seconds) and there will be a buzzing sound and flashing light.

4、 Attention

When there is no buzzing sound, flashing light, or "chirping" sound after self testing, the use should be stopped. Troubleshooting should be done according to the instructions.

When the self-test is interrupted, slowly move the detector back and forth. Page 1

Continuously use high sensitivity gears until the approximate position of the AC voltage is determined.

When the detector approaches AC power, it will produce a buzzing sound and LED display.

When the sensing part approaches the power supply, the buzzing sound and LED display will accelerate. When there is alternating current surrounding, occasional buzzing sounds may occur. This is normal when the detector is in motion, as it is caused by static charges in other areas.

The higher the detector is placed, the easier it is to detect the power supply.

Once the AC source is clearly detected, quickly switch to the low sensitivity or front center gear to accurately power. Do not touch conductors and do not place in liquids.

In addition to the setting of the switch, there are many other factors that can affect the indication of AC voltage danger by secondary signals. The detection sensitivity depends on the following factors:

(1) If the AC signal is shielded by a grounded metal, the detector will not be able to detect it. Metal doors and metal plates will prevent radiation from the AC magnetic field. If the metal object is connected or very close to the AC signal source, the detector will also sense. Some shielding objects such as wet leaves and trees can also narrow its range, so when there are trees or puddles near the communication source, the detector will remotely sound an alarm.

(2) The height of the detector above the ground and the height of the signal source both affect the distance between the AC source and the next alarm. The higher the detector is from the ground, the wider its detection range. Placing it on the ground limits its detection range. This is the same as the placement of wires.

(3) The higher the communication signal source, the easier it is to detect.

(4) The physical size of the conductor also affects the distance of the alarm. A car is easier to measure than a short section of AC wire.

Attention: Please select the highly sensitive gear when starting work

Position assessment: Hold the end of the lanyard and move it in different directions to observe the LED display light. If there is a signal display, stop moving. If the signal keeps alarming, try to find the source of the signal. The signal is enhanced, the frequency of the buzzing sound increases, and the detector is closer to the AC source. Reduce sensitivity or shift to the front center gear to accurately source. Page 2

B Vehicle accident: When the vehicle touches electrodes, transformers, buildings, traffic lights, or other devices, a detector can be used to detect whether the vehicle, wires, barbed wire, or surrounding materials are charged.

C Swimming Pool: When the lighting equipment or other electrical appliances of the swimming pool fall into the pool, it usually causes the pool to conduct electricity. Before rescuing the victim, a detector should be used to determine if there is any danger in the swimming pool.

Night search: At night, especially during searches with strong winds and hail, some trees or wires may become electrified, and detectors are used to determine if there is a risk of conductivity in the area being searched and rescued.

E collapsed buildings: Buildings after explosions, earthquakes, or storms will be connected to underground cables or secondary circuits, and detectors will be used to determine whether rescue work is safe.

F Fire: In the event of a fire, use detectors to confirm whether there is a risk of line connection and high voltage lines.

G Cleaning work: Rescue personnel will face the risk of leakage from emergency rescue auxiliary power generation equipment during cleaning work, and can use detectors to detect the power generation equipment.

5、 Replace battery:

Choose a safe, dry, and clean place

Place the detector flat on the table

Loosen the screw of the rolled flower lanyard, and the gray back cover with the buzzer's spring pressure will be pushed out

Pay attention to the installation of the two poles and the battery

The electrical contacts of the four batteries near the positive terminal of the battery pack are connected to the buzzer

Raise the front end of the detector to slide the battery out

The flat detector slides the new battery in

Be careful when replacing the back cover, pay attention to the place where the lanyard screws are inserted, and align them with the holes in the housing

Place the detector vertically, carefully cover the back cover, and tighten the tether screws

Inspection device. If self testing cannot be carried out, recheck whether the battery installation is correct on page 3

6、 Attention:

(1) Be vigilant during voltage detection and take appropriate measures after measurement.

(2) This equipment does not provide danger alarms for direct current.

(3) Cannot detect shielded AC voltage, and should be cautious when used in areas with multiple circuits, especially when using low sensitivity or front concentrated gears. When performing precise operations on one source, one should not neglect another source.

(4) When setting the front-end concentration, the detector will obtain a signal from the end prompt. Do not use this setting or low sensitivity setting at the beginning. The sensitivity of the detector may decrease or no longer receive signals from other directions. Be careful not to come into contact with undetected conductive wires.

(5) Be vigilant about automated testing. Use a detector to test whether the wire mesh or guide wire is truly safe. (6) Do not touch water or surrounding pools when unsure if there is danger.

(7) Even if the network cable has been disconnected, it is still necessary to use a detector to determine. When emergency power generation equipment or substitutes work, they can also cause voltage to be generated in the user's direction. A voltage of 120 volts is generated in the secondary circuit through overhead lines, resulting in a voltage of 7200V.

(8) Clean the detector with soapy water. The area near the back cover of the buzzer is not waterproof, so be careful not to let water enter during cleaning.

(9) This product does not come with a battery, which needs to be purchased separately.
