Understand the Device Specifications

Before you start calibrating, gain knowledge of your metal detector wall scanner specifics. Review the manual and identify the device’s sensitivity levels, detection modes, and the types of metal it can detect. By understanding these specifications, you can effectively operate your device and achieve accurate scanning results.

Familiarize Yourself with the Device Settings

Dive into understanding the functionalities of your scanner. Adjust the sensitivity levels, switch between detection modes, and identify what each type of metal detection symbol or alert indicates. Regular practice will enhance your skill set and ensure you get the most out of your device.


Check the Battery Level

Ensure your device has a full charge before starting any calibration process or accuracy check. Operating on a low battery can lead to inaccurate results due to insufficient power. For example, if you’re tuning a musical instrument with a digital tuner or mapping a route on a GPS system, the device’s readings might be off if the battery is nearly depleted. Prioritize charging your device fully to uphold its operational efficiency and accuracy.


Select the Appropriate Detection Mode

Opt for the detection mode that aligns with the specific metal you aim to scan. Many devices incorporate unique modes tailored for diverse metals like steel, copper, etc. Carefully read the user manual to fully discern and understand the different modes available on your particular device. Remember, correctly selecting the detection mode will result in a more accurate and efficient scanning process.


Adjust the Sensitivity Level

  • Set the Sensitivity Level: Firstly, it is critical to correctly set the sensitivity level of your device to match your specific needs. Remember, higher sensitivity results in the device being capable of detecting metals that are buried deeply within walls.

Example: If you are looking to detect pipes or wires that are embedded deep within a concrete wall, tuning your device to a higher sensitivity level would be ideal.

  • Surface Scan Settings: Alternatively, a lower sensitivity level is most suited for surface scanning, giving you just enough reach without causing unnecessary disturbances.

Example: When scanning for nails or screws in wooden planks, set your device to a lower sensitivity level to accurately target those items without going deeper into the material.

Follow these guidelines to maximize the potential of your scanning device and ensure an accurate detection based on your specific requirements. Utilize the correct imperative verbs and setting measures to facilitate precise control over your device sensitivity levels. Your scanning experience will significantly improve once you master these settings.


Perform a Test Scan

Initiate your test scan with a well-known metal object. This could be something as simple as a coin or a metal key. Position the object within the scanning field and execute the scan as usual. Observing the device’s response to this known metal object allows you to assess its capability and verify functionality. Should the device fail to recognize the metal object, this may indicate an issue that requires troubleshooting or device calibration.


Evaluate the Results

After the test scan is performed, carefully analyze its results. If your device fails to detect the known metal object, this may be indicative of the device requiring further calibrations. Make sure to adjust the device settings accordingly, paying attention to the calibration instructions as provided in the user manual. Regularly perform test scans and make necessary adjustments to ensure optimal performance of the device.


Re-adjust the Sensitivity Level

Should the device fail the initial test scan, immediately proceed to adjust its sensitivity level. Locate your device’s settings menu, find the sensitivity sliders or indicators, and modify to a desirable level. Once completed, conduct another test scan to assess if the adjustments have improved the device’s accuracy. Remember, the optimal sensitivity level varies per device and use case; therefore, iterative testing could be necessary to achieve the best results.


Contact Manufacturer Support

Should your device continue to struggle with detecting a known metal object, kindly reach out to the product’s manufacturer support team immediately. Begin by noting the model number and any specific issues you have experienced. This information is crucial in helping the technical team assess your problem. Then, locate the manufacturer’s support contact details from the device’s manual or official website. Call or email them, detailing your problem and any troubleshooting steps you have already taken.


Regularly Recalibrate the Device

Prioritize the regular calibration of your metal detector wall scanner to maintain its optimal functioning. The necessary frequency for this process may vary based on how frequently the device is used and the specific guidelines recommended by the manufacturer. Depending on these variables, establish a consistent recalibration schedule. Follow this schedule rigorously, as the performance and accuracy of your wall scanner are directly tied to its proper calibration.


Maintain the Device

Keep your device free from dust and dirt by cleaning it regularly. Use a soft, lint-free cloth to clean the exterior of the device. Avoid the use of harsh cleaners or excessive moisture to prevent damage.

Store Your Device Properly

Always store your device in a cool, dry place to prevent overheating and moisture damage. Avoid placing your device near heat sources or in direct sunlight. When not in use, it is advisable to keep it stored in a protective case for added protection.

Keep Your Software Updated

Ensure your device runs smoothly by keeping its software updated. Regularly check for updates and install them promptly. This not only enhances the functionality of your device but also can fix any potential security issues.

Manage Your Device’s Battery Life

Optimize the lifespan of your device by appropriately managing its battery life. Avoid overcharging and fully depleting the battery. Regularly recalibrate your battery by allowing it to drain completely and then fully charging it once every month or two.

Conclusion: Ensuring Optimal Calibration

Remember, calibration isn’t a one-time act but a consistent practice that guarantees long-term success. Continuously keeping a check on your metal detector will not only prolong its life but also enhance operation effectiveness. Armed with the information from this blog post, you are now capable of maximizing your wall scanner’s potential for high-level detection tasks with ease and precision.

Frequently Asked Questions on Metal Detector Wall Scanners

Can the scanner identify the type of metal it has detected?

The capability of a scanner to identify the type of metal it has detected largely depends on the specific model and technology of the scanner. While basic metal detectors can simply identify the presence of a metallic object, advanced scanners such as spectrometers or X-ray fluorescence (XRF) analyzers can accurately determine the composition of the metal detected. Please refer to the specifications of the particular scanner you are using for accurate information.

How deep can a metal detector wall scanner detect objects in the wall?

The depth at which a metal detector wall scanner can detect objects in the wall varies depending on the specific model and the type of material being scanned. However, on average, most devices can detect metal objects up to 3 inches (approximately 7.6 cm) deep, while for live wiring or plastic pipes it usually is within 2 inches (approximately 5 cm). For more accurate results, it is important to refer to the specifications provided by the wall scanner’s manufacturer.
