noyafa NF-517 Multifunctional Wall Detector

Products overview

This stud detector quickly locates wood, metal and AC wires hidden in the walls, floors, and ceilings of the house. It can work on different wall surfaces, such as lath, wallpaper wood flooring, acoustic ceiling, painted walls, etc. helping you avoid danger when installing TVs, cabinets, garage racks, etc.

Product description

Product function description

Metal detection function

Metal detection instruction Signal strongth digital range: 0~100%

•  Metal detection display & calibration processinstruction

Note: During the calibration process,keep the product as far away from metal as possible

Self-calibration process description

1. During the self-calibration process, the two symbols of will always flash at the same time.
2. Once the calibration is complete, the display will be solid.
3. Each time the device is powered on or enters metal detection mode, it will self-calibrate once.
4. Calibration can be performed again by pressing the key.

Metal detection process description

1. The digital display value of signal strength is proportional to the analog bar of signal strength.
2. The higher the analog bar and the larger the digital display value, the closer it is to the directly above the measured object.
3. When the signal analog signal bar (100%) appears in it means it is directly above the detected object

Wood detection function

Wood detection Instruction

1.  Wood detection
2. Signal strength digital range: 0-100%

Wood detection working process

Self-calibration process description

1. During the self-calibration process, the two symbols of will always flash at the same time.
2. Once the calibration is complete, the display will be solid.
3. In wood detection mode, the device will self-calibrate once when it is close to a wood wall.
4. Calibration can be performed again by pressing the key.

Wood detection process description

• The digital display value of signal strength is proportional to the analog bar of signal strength.
•  The higher the analog bar and the larger the digital display value, the closer it is to the directly above the measured object.
• When the signal analog signal bar (100%) appears in , it means it is directly abovethe detected object

AC Detection (NCV)

AC detection instruction

1. The AC detection function is divided into 3 gears.
2. Press the AC detection mode button to enter the AC detection, the sensitivity gear is02 (default).
3. Short press again to switch to AC detection sensitivity 03.
4. Short press again to switch to the AC detection sensitivity 01 gear, and the detection gear can be switched in turn

AC detection working process

Note Short press the AC detection D button in turn to switch back and forth between 3rd gear or 1st gear

AC detection instruction

1. During AC detection, when the instrument detects AC, the instrument interface will display the icon. When the instrument does not detect AC power, the instrument interface will not display the icon. And the digital display value of signal strength is proportional to the analog bar of signal strength.
2. Signal strength digital range: 0-100%, corresponds to analog bars.
3. Sensitivity level: 01-02-03, the default is 02, sensitivity cycle mode: 02~>03~>01~>02~>03.Level 01 has the highest sensitivity and the farthest detection distance

LED signal indicator description

1. No signal is detected and the LED light does not light up.
2. When the detected signal value s30%, the LED light turns green.
3. 30%Sdetected signal values60%, the LED light turns on.
4. 70%Sdetected signal value, the LED light turns red.

Backlight function

The backlight will automatically turn on when powered on. If there is no operation for 3 minutes, the backlight will automatically turn off.

Automatic shutdown function

After turning on the device, if there is no operation within 5 minutes. it will automatically shut down.

Replacement battery reminder function

After the instrument is turned on or during operation, the battery power symbol on the interface displays D›, which means that the current battery power is exhausted and the battery should be replaced immediately.
