Multifunction Wall Detector Scanner Large Area Sensor For Metal Nonmetal AC Wire Finding With LCD Display And Beep
Test operation:
After the sampling is successful, do not release the power switch and move along the surface to be tested. When the instrument detects a foreign object, the red indicator light starts to light up in sequence. When the LED is all on and makes a “dripping” sound, use a pencil to do the next step. Check and release the power switch.
Put the instrument in the opposite direction of the surface to be sampled and approach the marking position. When the instrument detects a foreign object, the Red indicator lights begin to illuminate in sequence. When the LEDs are all on and make a “dripping” sound, use a pencil to mark the next mark and release the power switch.
Repeat the test several times, if the alarm is issued, that is, there may be support pillars (foreign objects) under the middle area.
When there are no metal objects or other foreign objects under it, it will not flash or sound. To get the accuracy of the test results, you can test it several times.
