3 in 1 Multi-function Wall Tester Stud Finder Wooden Column Voltage Density

Feature
Advantages of the product:Suitable for use in interior decoration structures. It can respectively detect the position of metal, wood, and live circuits in the wall. When metal, wood, and live circuits are sensed, the instrument will have an analog bar display and sound prompts.
Product technical features
This instrument is designed using the principle that the change in the density of the substance below the surface of the detected object causes the frequency of the detector to change. It can test metal, wood, and charged circuits separately, and the maximum detection depth is under the surface of a uniform object
Wood 30*30mm:≤18mm
Metal detection depth:iron pipe Φ25mm, ≤30mm
AC poweriline:90 ~ 250V≤50mm
Test sampling
Place the instrument on the surface of the object to be measured, lightly press the power switch next to it for 2 seconds to turn on, press the middle selection key to select the type of object to be measured, press the power key to sample, and a beep will sound, indicating successful sampling.
Test operation
After the sampling is successful, do not release the power switch and move along the surface to be tested. When the instrument senses a foreign object, the analog bars on the LCD screen will start to display one by one. When the analog bars are fully lit and make a “drip” sound, use a pencil to do it. Make the mark and release the power switch.
Place the instrument on the opposite direction of the surface for sampling, approaching the position where the mark is made. When the instrument senses a foreign object, the analog bars on the LCD screen begin to display in sequencie. When the analog bars are fully lit and make a ‘drip’ sound, use a pencil to do the next step. Mark and release the power switch.
Repeat the test several times, if the alarm is issued, that is, the object under test may be under the middle area.
When there is no corresponding test object below, it will not display or sound. In order to test the results accurately, you can test several times.
Note
-The size might be slightly different due to manual measurement. Your kindly understanding would be appreciated.
-The color of the item may vary slightly due to photography and different PC monitor.
