Description

Features: 1. 100% brand new and high-quality products. 2. Made of high-quality materials, durable and practical. 3Suitable 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, and it can also detect other foreign objects in the same object. 4 Ergonomic design, comfortable to use. 5. Look for the edges of wood or metal rivets up to 3/4 inch (20 mm) deep. Test sampling: Place the instrument on the surface to be tested and press the power switch. At this time, the first indicator red and green lights are on, and a beep sounds, and then the red indicator turns off, indicating success. When sampling, the first red indicator is red. The indicator light is always on and emits a short beep, indicating that the sampling is unsuccessful, there is interference, or the measured object exceeds the built-in allowable value. 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 red indicator light starts to light up in sequence. When the LED is all on and emits a "drip" sound, use a pencil to do the next step. Mark and release the power switch. Place the instrument in the opposite direction of the surface for sampling, and approach the marking position. When the instrument senses a foreign object, the red indicator lights start to light up in sequence. When the LEDs are all on and make a "drip" sound, use a pencil to make the next mark , 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 underneath, it will not flash and make no sound. For the accuracy of the test results, you can test several times. The main parameters: Power supply: 6F22 type 9V battery (this product does not have a battery) Product size: 145x62x25mm Product weight: about 71g (without battery) 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. The maximum detection depth is 19mm below the surface of the uniform object, the detection range error is 3mm, and the range of the detected object cannot be less than 1200mm2 Package list: 1* Bare watch (without battery)  1* Manual  1* Carton packaging
