The material detectors are measuring tools that allow you to see what is inside walls and floors, being able to identify pipes, metals, cables, beams and other elements.
And although this tool is very popular with contractors, in this article we will collect the 10 most common mistakes and faults that we must avoid when using this essential tool.
The material detector can give a bad measurement in these cases
1. Move the detector very fast
Despite the detectors they work with agility and dexterity when manipulated correctly on any surface, move the detector slowly and continuously It is the key to obtaining better results.
For proper use, always place the material detector flat against the surface.
2. Interference caused by other materials in the environment
Although some detectors of materials They are not approved to work in explosive environments, such as in the presence of flammable liquids, gases or dust, the measurement values may also be affected in safer environments under certain environmental conditions.
These include, for example, the proximity of other equipment that produces strong magnetic or electromagnetic pulses. Moisture and other insulation materials could also interfere.
Also, the use or operation of transmission systems in close proximity, such as WLAN, UMTS, radar and microwave, can influence the measurement function.
3. Not having the right detector for each type of material
Not have a specific detector for the task we are going to carry out It could be cheaper, although we would be very limited to detect other functions.
If we want to detect the beams behind a dry construction, a tool detecting wooden beams will do. But if the construction includes pipes, live cables and other elements, we need a tool measurement that detects all these materials at an ideal distance for the work.
4. Work on wet materials
The wall scanner normally works on walls covered with wallpaper or fabric. In case the wall is covered by metallic sheets, contains metallic fibers or its covering is still wet, it is advisable to wait for any application to dry before using the detector.
5. Misinterpret the signals communicated by the tool
Not knowing or misinterpreting the signals emitted by the tool During the location of materials, it can lead us to a path of continuous errors that could seriously harm our work.
It is imperative to know each of the commands, settings and signals of the material detector before using it on a new project.
Currently most brands have dynamic online presentations, video tutorials and downloadable manuals to learn everything about each model, a great advantage for users.
6. Make a home repair
Another mistake is to perform a repair to the tool with personnel not competent for the task. Repair the tool Only by qualified specialists using original spare parts.
7. Damages caused by maintenance or storage
The tools The measuring devices should be protected from moisture and direct sunlight. Do not submit the tool measurement at extreme temperatures or sudden temperature variations.
In case of extreme temperatures or variations in temperature, the accuracy of the measuring tool and the display indication may be impaired.
In the event of large temperature variations, it allows the detector Adjust to room temperature before use.
8. Place metal objects on the tool
Attaching any metal identification adhesive or sticker affects the measurement results on metal plates.
Other types of magnetic identifiers could also affect the sensor.
9. Not taking into account the depth of the building
For thin walls the material detectors with electronic technology, which detect all kinds of materials in plaster walls quite accurately.
But if we want to identify deeper objects, knowing how deep they are, or if, for example, we need to locate plastic water pipes, it will be highly recommended to acquire one tool with radar technology.
10. False positives
One of the recurring failures in material detectors are the false positives. The erroneous detection of non-existent objects.
This happens due to unfavorable conditions or interference at the measurement site or because the tool it is being used on an unsuitable surface.
Therefore, it is always recommended to read the instructions and check that the device’s sensors are compatible with the surface we are going to work with.
Helpful Tips to Improve Detector Performance
- Si the tool does not turn on, it may just be a problem of batteries. Check by inserting the batteries again with the correct polarity, if they don’t work, replace them.
- If the instrument is too hot or too cold, wait for it to acclimate to the correct temperature for operation.
- Check the detector every time you use it. In case of visible damage or loose components within the tool measurement, its accuracy can no longer be guaranteed.
- Keep the tool clean and dry measuring tube to ensure proper and safe work. Clean up debris or contamination that covers the tool With a dry cloth, do not use cleaning agents or solvents.
- Do not submerge the tool measurement in water or other fluids.
A material detector is a tool extraordinary that allows us to locate essential elements for construction.
However, we must bear in mind that there are a number of factors that can affect the measurement results, so we must be very careful and responsible in their use. On our experience depends a clear and accurate measurement.
