Overview
Feature:
1. Power supply: 6F22 type 9V battery
2. Product size: 145x62x25 mm
3. Product weight: about 71g (without battery)
4. This instrument is designed based on the principle that the change in the detector frequency changes due to the change in the density of the material below the surface of the detected object.
5. Advantages of the product: Suitable for use in interior decoration structures. It can detect the position of metal and wood in the wall. When metal and wood are sensed, the instrument will flash and sound. It can also detect other foreign objects in the same object
Test sampling:
Place the instrument on the surface to be tested, press the power switch, at this time the first indicator red and green lights are on, and a “drop” sound is emitted, then the red indicator light goes out, indicating success. When the first red The indicator light is always on and a short “dipping” sound is emitted, indicating that the sampling is unsuccessful, there is interference or the measured object exceeds the built-in allowable value.
Test operation:
1. After the sampling is successful, do not release the power switch and move along the measured surface. When the instrument senses a foreign object, the red indicator lights will start to turn on sequentially. When the LED is fully lit and a “drop” sound is emitted, use a pencil. Make a mark and release the power switch.
2. Place the instrument in the opposite direction of the surface for sampling, and approach the marked position. When the instrument senses a foreign object, the red indicator lights will start to turn on sequentially. When the LED is fully lit and a “drop” sound is made, use a pencil Make a note and release the power switch.
3. Repeat the test several times, if all alarms are issued, that is, there may be support columns (foreign objects) between the middle areas.
4. When there is no metal or other foreign matter underneath, it will not flash or sound. In order to test the accuracy, you can test more times.
