The Multi-functional Stud Finder MD220 is designed for identifying objects within walls, ceilings, and floors. It can detect various substances, including metals (both magnetic and non-magnetic), joists, wood, live AC wires, and water-filled plastic pipes.

Important Information

1. Safe Instructions

– Working safely with the detection tool is only possible when the operating and safety information are read completely and the instructions contained therein are strictly followed.
– Read all instructions. Failure to follow all instructions may result in electric shock, fire, and/or serious injury.

2. Limits of use

– Preserve these instructions.
– The detector’s ability to detect objects is influenced by the proximity of equipment producing strong magnetic or electromagnetic fields, as well as by moisture, metallic building materials, foil-laminated insulation materials, or conductive wallpaper. Therefore, the use or operation of transmitting systems (e.g., WLAN, UMTS, radar, transmitter masts, or microwaves) in close proximity can influence the measuring function.
– Inconsistencies in surface material thickness, such as plaster and lath, can affect the detector’s ability to detect wood substructures (studs).
– Do not solely rely on the detector; use additional sources such as construction plans, visible entry points of pipes and wiring into walls (e.g., basement), and standard 16″ and 24″ stud spacing practices before penetrating the surface.

– Before penetrating a surface with a drill, router, saw, or nail, always turn off electrical power, gas, and water supplies to avoid personal injury.
– Due to technological limitations, the measuring tool cannot ensure 100% certainty. Safeguard yourself before drilling, sawing, or routing in walls, ceilings, or floors using other information sources, like building plans or construction phase pictures. Environmental factors, such as humidity or proximity to electrical devices, can affect the accuracy of the measuring tool. Surface quality and wall conditions (e.g., moisture, metallic building materials, conductive wallpaper, insulation materials, tiles), and the type, size, and position of objects can lead to inaccurate measurements.
– Avoid operating the measuring tool in explosive environments with flammable liquids, gases, or dust, as sparks generated in the detection tool may ignite dust or fumes.
– Prevent exposure to direct sunlight. Avoid subjecting the measuring tool to extreme temperatures or temperature variations, such as leaving it in vehicles for extended periods. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation.
– Hold the measuring tool only at the designated grip area. Detection results are affected when hands are in front of or behind the sensor area.
– Measuring values can be affected by ambient conditions, including the proximity of devices generating strong electric, magnetic, or electromagnetic fields, moisture, metallic building materials, foil-laminated insulation materials, or conductive wallpaper or tiles.

– Do not immerse the tool in water or other fluids.
– Wipe away debris or contamination with a dry, soft cloth. Do not use cleaning agents or solvents.
– In order not to affect the measuring function, decals/stickers, or nameplates, especially metal ones, may not be attached in the sensor area on the front or back side of the measuring tool.
– Do not remove the contact pads on the back.
– Do not open or repair the detection tool yourself or by non-professionals.

3. Electrical Safety

Always follow all instructions and warnings on battery labels and packaging to handle batteries so that they do not explode or leak and pose a risk of injury or fire.

– Do not short any battery terminals.
– Do not dispose of batteries in fire.
– Keep batteries out of reach of children.
– Remove batteries from the tool when not in use for extended periods to prevent corrosion and discharge.
– Dispose of batteries per local code.

2. Place the tool on the object’s surface, and always move the tool slowly in a straight line after choosing the correct detection operating mode.

When the tool is on the object’s surface, the illuminated ring lights up green and signals operational readiness.
Always move the measuring tool over the base material applying light pressure, without lifting it off or changing the pressure.

3. During detection, the screen displays the real-time position of the measured object and shows the signal strength.

Detector Mode

There are three detect modes: Multi-functional Detector Mode, Metal Mode, Live AC Wire Mode. The currently selected detection mode is displayed in the upper right corner of the screen, to the left of the battery icon.

Choose the appropriate detection mode based on the target material. If the material of the object within the wall is unknown, start with the
Multi-functional Detection Mode. Once the object’s material is identified through the
Multi-functional Detection Mode, switch to the specific mode for more accurate detection.

– Select “Multi-functional Detector Mode” for a maximum depth of non-metal detection.
– Choose “Metal Mode” for a maximum depth of metal detection.
– Opt for “Live AC Wire Mode” for the maximum depth of charged AC wire detection.

1. Multi-functional Detector Mode

Multi-functional Detector Mode can detect the following items within a wall:

– Magnetic metals: ferrous metals containing iron, cobalt, or nickel.

– Non-magnetic metals: aluminum, copper, lead, tin, titanium, zinc, and alloys such as brass and bronze.
– Non-metal: wooden beams, plastic pipes filled with water. Empty plastic pipes are typically not detected.
– Charged objects, for example, electric wires.

This mode is primarily used for detecting non-metallic objects, or when the material of the target object is unknown. Use this mode to initially identify the material of the detected target object. Once the target object inside the wall is recognized as metal or live AC wires, switch to the appropriate mode for more accurate detection.
The scanners in this model use advanced microwave detection technology. The signal penetrates the material being scanned, and the return signal is analyzed to determine the composition of other substances in the material. The accuracy of detection may be affected by factors such as density, thickness, and composition of the material being scanned. In terms of accuracy and scanning depth, the measurement result can be inferior in case of unfavorable surface quality of the base material.

Operating Steps:

1. Press the Multi-function Detector Mode button, and the illuminated ring lights up green, activating the multi-function detector mode.

2. When no objects are detected, the illuminated ring is green, and there is no object icon on the screen. When an object is detected, the object icon appears on the screen, and the illuminated ring turns orange. The signal strength is displayed at the bottom of the screen in the left and right directions of the scanner.
3. If the object icon is to the right of the center, move the scanner to the right. If it’s on the left, move the scanner to the left.
4. When the object icon is in the center, coinciding with the center positioning icon, and the scanner emits a beep, it means the scanner has pinpointed the object. If the signal strength bar stabilizes, the scanner has accurately located the object. If the signal strength display bar has a higher amplitude, move the scanner to redetect.

NOTE:

– If the left and right signal strength bars are consistently high or not stabilized, restart the measurement program at a different location.
– If the flashing lightning icon appears in the upper right corner and the illuminated ring continues to flash red, switch to Live AC Wire Mode for accurate detection.

2. Metal Mode

Metal Mode is primarily designed to detect both magnetic and non-magnetic metal objects.

Operating Steps:

1. Press the Metal Mode button; the illuminated ring lights green, indicating the activation of Metal Mode.

2. When no object is detected, the illuminated ring remains green, and there is no object icon on the screen.
   Upon detecting a metal stud, a stud icon appears on the screen, the illuminated ring turns orange, and the estimated distance from the scanner to the studs is displayed at the bottom of the screen.

3. If the stud icon is on the left side of the screen, it indicates the stud is on the right side of the scanner. Gradually move the scanner to the right for precise positioning. If the stud icon is on the right side, it means the stud is on the left side of the scanner. Gradually move the scanner to the left.

4. When the stud is in the center of the scanner, the illuminated ring turns red, a beeping sound occurs, and the screen displays the word “center.” Simultaneously, the depth is displayed in the left/right bottom corner of the screen, with units shown in inch/metric.

NOTE:

– If the signal strength in Metal Mode is not 0 when the tool is suspended, manual calibration is required. Press and hold the Metal Mode button while the tool is suspended; the illuminated ring will flash during calibration, and the words “MET CAL” will appear on the screen. Calibration is complete when the illuminated ring turns green.
– If the amplitude of the depth analog display bar is consistently high or does not stabilize, the target has not been accurately detected. Restart the measurement program by placing the probing tool at a different location on the substrate.
– If the flashing lightning icon appears in the upper right corner of the screen, and the illuminated ring continues to flash red, it indicates the object is electrified. Switch to Live AC Wire Mode for accurate detection.

3. Live AC Wire Mode

Live AC Wire Mode is exclusively designed for detecting “live” conductors (110-230V).

Operating Steps:

1. Press the Live AC Wire Mode button; the illuminated ring lights green, indicating the activation of Live AC Wire Mode. When no objects are detected, the illuminated ring remains green, and there is no object icon on the screen.

2. Upon detecting an energized wire, the wire icon appears on the screen, the illuminated ring turns red and continues to flash, accompanied by an audible beep. The bottom of the screen displays the signal strength of the scanner in the left and right directions.
3. If the wire icon is to the right of the center of the screen, the wire is on the right side of the scanner. Gradually move the scanner to the right to pinpoint the location. If the wire icon is on the left side, it means the wire is on the left side of the scanner. Gradually move the scanner to the left.
4. When the wire icon is in the center of the scanner, coinciding with the center positioning icon, the scanner emits a sharper beep. When the signal strength bar at the bottom of the screen stabilizes, it means the scanner has pinpointed the wire. If the signal strength display bar has a higher amplitude, move the scanner to redetect it.

NOTE:

– Due to signal strength being affected by the wire’s position, move the measuring tool repeatedly over the area to localize the “live” conductor several times. It can be indicated very accurately. When the tool is very close to the conductor, the illuminated ring flashes red, and the audio signal beeps swiftly.
– “Live” conductors are easier to detect when power consumers are connected to the sought conductor and switched on.
– Under certain conditions (such as below metal surfaces or behind surfaces with high water content), “live” conductors cannot be securely detected.
– Static electricity can lead to inaccurate indication of electric lines. To improve the indication, place your free hand flat on the wall next to the measuring tool to remove static electricity.
– Due to the inherent danger of electricity in construction, security considerations prioritize the detection of charged wires.
– If the amplitude of the left and right signal strength analog bars in the display is consistently high or not stabilized, the target has not been accurately detected. Restart the measurement program by placing the probing tool at a different location on the substrate.
– Less scanning depth for wires while the conductors are not “live”.

Working advice

1. Marking objects

If necessary, detected objects can be marked.

2. Temperature Control

The measuring tool is equipped with a temperature control indicator.
When the temperature control indicator lights up, the measuring tool is not within the operating temperature range or has been subjected to large temperature variations. Switch the tool off and allow it to adjust to the ambient temperature before switching it on again.

3. Warning function

– Check the measuring tool each time before use.
– Keep the tool clean and dry at all times to ensure proper and safe working.

Problem and Solution

Problem 1: In Multi-functional Detector Mode, the illuminated ring flashes red continuously, a flashing lightning bolt icon is in the upper right corner of the screen, and no object icon is displayed in the center of the screen.

Solution: This indicates a charged wire detection. Press the Live AC Wire Mode button for accurate wire detection.

Problem 2: The scanner is not scanning any material, and even with the scanner fixed in the air, the scanner still shows some detections.

Solution: Calibrate the scanner manually.

1. In Multi-functional Detector Mode: Hold the scanner against the surface of the material being scanned and press and hold the Multi-functional Detector Mode button for 3 seconds; the scanner will emit 2 beeps, indicating calibration completion.
2. In Metal Mode: Press and hold the Metal Mode button while the tool is suspended; the illuminated ring will flash during calibration, and the words “MET CAL” will appear on the screen. Calibration is complete when the illuminated ring turns green.

Problem 3: The object icon is not displayed on the screen while scanning.

Solution: 1) The calibration may be incorrect. Move and recalibrate the scanner in different places following the correct method in question 2.
2) The stud is out of depth for the scan mode. Try scanning again with Metal Mode that can detect the maximum depth.

Problem4: In Multi-functional Detector mode, the object icons displayed on the screen are constantly changing.

Solution: 1) Calibrate the scanner using the correct method first.
2) Different materials of studs inside the wall may cause this. Use different detection modes for more accurate detection.
3) Plastic pipes filled with water may be judged as wooden beams due to environmental factors. Perform multiple detections at different locations.

Problem 5: The scanner is not scanning for charged objects, but the scanner still indicates that a charged conductor is detected.

Solution: Static electricity can lead to inaccurate indication of electric lines. To improve the indication, place your free hand flat on the wall next to the measuring tool to remove static electricity.

Problem 6: Difficulty detecting metal.

Solution: 1) The scanner may have been calibrated over a metal object, reducing sensitivity. Try calibrating in another location.

2. Metal targets too deep or too small. Scan in both horizontal and vertical directions. Metal sensitivity is increased when the metal object is parallel to the sensor and located under an item. In the metal mode, the maximum detection depth can be 120 mm. If this depth is exceeded, the scanner cannot detect it.

Problem 7: Constant readings of studs near windows and doors.

Solution: Double and triple studs are usually found around doors and windows. Solid headers are among them. Detect the outer edges where you know.

Problem 8: Suspect there are electrical wires, but do not detect any.

Solution: 1) Wires may be shielded by metal conduit, a braided wire layer, metallic wall covering, plywood wall, or other dense material. Wires deeper than 1.97 inches (50mm) from the surface might not be detected. Try Metal scan mode to check for metal conduit. If a switch controls an outlet, make sure it is ON for detection.
2) Exercise extra caution if the area has plywood, thick wood backing behind drywall, or thicker than normal walls.
3) Wires might be without electricity.

Problem 9: The scanner’s battery level is clearly displayed, but it suddenly shuts down. After restarting, the screen briefly displays a snowy screen before shutting down again, and the scanner cannot start.

Solution:
– This issue may stem from an unstable power supply to the device. Press and hold the power button for 10 seconds to force a restart.
– If the scanner continues to fail after multiple attempts, please use the provided USB cable to connect it to a 5V/2A charging adapter. Charge the scanner for 30 minutes and then attempt to restart. (Adapter not included).
– If the problem persists, kindly reach out to our after-sales team for further assistance.
– While the scanner can operate while charging, please note that it may impact detection results and battery life. Extended use of the scanner in this manner is not recommended.
