Why can't I detect wood, metal and wires behind the wall, I'm sure it's inside?
Please make sure you are using the correct mode, there are three thickness detections in STUD mode, 0.5 inch, 1 inch, 1.5 inch thickness; another case is that your wall thickness has exceeded the detection range of the detector.
Why are the test results different in the same place, sometimes it can be detected, sometimes it does not respond?
Please keep the same hand position from the beginning of the calibration to the end of the measurement, do not shake, tilt or press the product during the movement, move the product horizontally or vertically to scan.
Why can't I scan for wires and how can I be sure there are wires inside?
Use AC mode to detect the location of the marker and around the marker point. If AC mode detects an object, it means the metal is a wire. If there is no response, it may be other metals, please cooperate with other functions to accurately detect.
Why do I still have to scan wires in non-ac mode?
In any mode when real-time AC voltage is detected, an AC alert indicator will appear on the display. In this case, or when field AC wiring is present, use extreme caution. This feature is a wire safety alert.
I don't quite understand how to operate this instrument, how to use it?
Please read the second to fifth points of the manual in detail to explain the specific use and functions of the instrument in detail. Please read the brochure "HELPFUL HINTS"
