Detect metal objects (steel bar, wire, copper pipe)

The maximum metal detection depth is 100mm

When detecting metal objects, press the metal detection button to enter the metal detection state. At this time, the metal detection pattern will appear on the display screen, and the green indicator light will be on.

Place the detector on the surface of the detector and move the instrument to the left or right in the same direction. As the instrument gets closer to the metal object, the scale on the signal intensity display area of the display screen will gradually rise and the intensity percentage will gradually increase. As the instrument moves away from the object, the scale drops and the intensity percentage decreases. When the program determines that the signal received by the instrument reaches its maximum value, the metal object is positioned directly below the center of the detector. The Center icon (Center) is displayed on the display screen.

When metal is detected, the yellow or red light on the detector lights up, and there is a constant sound from the instrument.

The red light on the detector flashes when it detects both the metal and the ac signal,And a beeping sound came from the instrument.

When the detector displays a nonmagnetic metal symbol, it indicates that the current object being measured is generally a wire or copper pipe.

When the magnetic metal symbol is displayed on the detector, it indicates that the currently measured object is generally steel bar.

When the detector does not display magnetic or non-magnetic metal symbols, it indicates that the currently measured object is generally an alloy.

When the alternating current symbol on the instrument flashes, it indicates that there is an alternating current signal nearby.

Note: when detecting metal, the detection depth value will be displayed on the display screen synchronously with the detection operation. The accuracy of the depth value is related to the shape and material of the metal being measured, the distribution of the relative detector of the object being measured, and the surrounding media properties of the object being measured. When the measured object is standard steel bar with diameter of 18mm or copper tube with diameter of 18mm, the accuracy of depth value is the best. Otherwise, the depth value can only be used as a rough reference value.

Warning!

In some cases, tools may not be able to accurately indicate live wires in walls if internal equipment fails or is not properly operated, so do not rely solely on the instrument to identify the presence of dangerous live wires. Other evidence, such as construction drawings or visual identification of wiring or pipe entry points, should also be used.

Warning!

If the wall contains live wires, do not take potentially dangerous measures. Be sure to turn off power, gas, and water before turning holes or studs penetrate the wall surface.

• Concrete, brick, and ceramic surfaces have shielding effects on electric field signals from the firing line, so when tested on these surfaces, ac signal detection is affected.

Ac signals can be detected more easily when the appliance is connected to the desired conductor and turned on.

• "live" wire signals will spread from both sides of the actual wire, so sometimes the "live" wire alarm area looks much larger than the actual wire

• Ac signals come mainly from live wires, and may also come from static or induced electricity in the environment. Placing your hand on the wall next to the detector may help eliminate static and inductive electricity.

• The signal strength of a "live" wire depends on the location of the cable. Therefore, take further measurements nearby or use other information to check for "live" wires.

• non-" live "wires may be detected as metal objects, and thin wires may not be detected.

Foreign body detection (generally referred to as a wooden block)

• Maximum detection depth: exact mode: 20mm; deep mode: 38mm. Long press the button to switch exact mode /deep mode

• The foreign body detection mode will detect objects in gypsum drywall, plywood sheaths, bare wood floors, and coated wood walls.

•The foreign body detection mode does not detect the concrete, mortar, lumps, bricks, carpets, foils, metal surfaces, tiles, glass or any other dense material.

• Sensitivity depth and accuracy will vary due to moisture content, material content, wall texture and paint.• The foreign body detection mode actually detects more than just wood blocks. It can also detect metals and other dense materials, such as water pipes and plastic pipes near the back of walls or ceiling surfaces. To help identify the wooden stall, first scan the metal and mark the location of any detected metal objects. The scan is then performed in the foreign body detection mode. The items detected in the foreign body detection mode but not detected in the metal detection mode may be wooden studs.

Press the wood button to enter the mode of detecting foreign matter, and an icon of detecting foreign matter (generally referring to wood file) will appear on the display screen.

When detecting foreign bodies, the instrument must be vertically attached to the wall and then press the button for detecting foreign bodies. Keep the instrument stationary for 1-3 seconds and wait for the completion of instrument calibration (the green light is on at this time) before conducting the detection operation.

Place the detector on the surface of the probe and move the instrument evenly and slowly to the left or right in the same direction. Do not lift the instrument or apply additional pressure.

When the instrument is close to the edge of the wooden bar of the object to be measured, the display screen will display the signal percentage synchronously, and the boundary icon with the same direction will gradually display.

When the instrument is on the Edge of a wooden block, the Edge character (Edge) will be displayed and the corresponding Edge icon will be displayed. Continue to move the instrument in the same direction, Edge character (Edge) off, the other half of the Edge icon gradually displayed；When the instrument is in the middle of the wooden stall, the Center character (Center) is displayed on the display screen and all the border icons on both sides are displayed. The red light will be on and the buzzer will "drip...". Long beep, maximum signal percentage.

Now keep moving in the same direction,the center cross icon and character are extinguished, the buzzer stops sounding, and the boundary icon is gradually extinguished with the departure of the instrument.When the instrument is at the other Edge of the wooden file, the Edge character (Edge) will be displayed on the instrument and the border icon on the corresponding half side will be displayed. The display screen will display the signal percentage synchronously. Continue to move the instrument until it is far away from the wooden block. The signal percentage gradually decreases and the boundary icon gradually disappears. when the instrument cannot detect the wooden block and the green light is on.The detection operation is completed
