Home Improvement:：How does an electronic stud finder work?
They are normally handheld devices, which are used to sense where the material behind the device is denser.
And the electronic stud finder works using changes in capacitance generated by density difference to determine where the stud is. When the plate inside the stud finder is over the wall, it senses one dielectric constant, but when it is over a stud, the dielectric constant changes. The circuit in the stud finder senses the change and shows it on its display.
When you start a home project such as hanging pictures, mounting your new TV, or renovating your house，the stud Finder can reduce unnecessary losses and damages, and the Tavool stud finder should be one of the helpful tools you certainly need. Tavool stud finder can make difference when you want a simple and successful DIY home project.
Tips and tricks for using Tavool stud finders-TH511:
Step 1: Calibrate the device before every scan
After choose the mode, press and hold the scan button (on the side) to calibrate it. Wait until the reducing bars disappear completely and the beep sounds, and then the calibration is completed.
Note: If you want a stud mode, calibrate it on the wall where you want to detect; For AC/Metal mode, please hold it in the air to calibrate it.
Step 2: Scan the wall
Hold down the button, then move the stud finder along the wall slowly. You should re-calibrate it when the scanner gets a shake or lift accidentally
The narrow on the screen together with the beep signal changing, would direct you to find the exact location of the targets.
Tips: If the scanning doesn’t work well, please switch to a proper depth mode, re-calibrate and scanning again for a better location
Step 3: Find the location of the stud
When the signal bar is full and the beep alarm is loudest, it means you find the center of an object. Mark it with your pencil.
Then you can switch to the Metal Scan mode to test whether it is a metal. You could also confirm the metal with the magnet at bottom of this device. If not a metal, it indicates that you find the center of a stud. Then you can drill it to hang something
Tips: For a more accurate metal location range, you can re-calibrate the device at the edge you’ve marked and then scan again.
