Introdución
The PREXISO 5-in-1 Multi-Purpose Detector is a versatile tool designed to assist with various home improvement and construction tasks. It combines the functions of a stud finder, metal detector, AC wire detector, laser level, and ultrasonic distance measurer. This manual provides detailed instructions for safe and effective use of the device.
Información de seguridade
- Seguridade con láser: This product is a Class II laser with an output power less than 1mW. Avoid direct eye exposure to the laser beam.
- Sharp Needles: The auxiliary laser marking stud button features sharp needles. Exercise caution when pressing this button to prevent injury. These needles are intended for use on wallpaper and wooden surfaces only. Do not use on stone, metal walls, or low-density plasterboard.
- Detección de cables de CA: Always be aware of the potential presence of live AC wires behind walls. The device will provide an audible and visual warning when AC wires are detected. Take appropriate precautions to avoid electrical hazards.
- Factores ambientais: Increased moisture on wall surfaces can affect the device's conductivity and may lead to inaccurate readings. Ensure surfaces are dry for optimal performance.
- Ultrasonic Measurement Accuracy: The ultrasonic distance measure function is intended for rough reference only and may not be as accurate as a laser distance measure.

Instrucións de funcionamento
1. Calibración
Before each use, especially for stud and metal detection, the device requires automatic calibration for maximum reliability and accuracy.
- Turn on the stud finder.
- Place the device flat against the wall surface where you intend to scan.
- Press and hold the scan button (usually on the side) until calibration is complete. The display will indicate when it's ready.
- Keep the button pressed down during the entire scanning operation.
2. Stud, Metal, and AC Wire Detection
This device offers three scanning modes to locate concealed objects:

Figure 2: Locating Concealed Objects
- Seleccionar modo: Use the Material Switch to select between STUD, AC WIRE, or METAL mode.
- Calibrar: Perform calibration as described above.
- Escanear: While holding the scan button, slowly slide the device horizontally across the wall surface.
- Detección: When an object is detected, the LCD screen will display arrows indicating its location, and an audible beep will sound. The center of the object is indicated by a solid dot on the screen.
- Marcación: Use a pencil to mark the detected location.
Detection Depths:
- Wood Studs: Up to 1 inch (24mm) deep in drywall.
- Metal Objects: Up to 1-1/2 inches (38mm) deep.
- Live AC Wires: Up to 1-3/8 inches (35mm) deep.

3. Laser Marking
The device can project a horizontal laser line for accurate leveling, useful for hanging pictures or shelves.

Figure 4: Laser Marking in Use
- Seleccionar modo: Slide the Function Switch to the LASER position.
- Dispositivo de posición: Place the device against the wall at the desired height. Use the built-in bubble vial to ensure the device is perfectly horizontal.
- Adjust Laser: If needed, use the plastic flip on the back to adjust the laser line position for uneven walls.
- Marca: The laser line will project across the wall, providing a guide for marking.
Caution: The stud button with needles is for auxiliary laser marking on wallpaper and wooden surfaces only. Do not use on stone or metal walls, or low-density plasterboard. Ensure the stud pins protector is engaged when not using the needles.

4. Ultrasonic Distance Measurement
This function allows for measuring distances, areas, and volumes using ultrasound.

Figure 6: Ultrasonic Distance Measure Functions
- Seleccionar modo: Slide the Function Switch to the DISTANCE position.
- Distancia de medida: Point the ultrasound sender/receiver towards the target surface. Press the measurement button. The distance will be displayed on the LCD.
- Medición de área/volume: Follow the on-screen prompts to take multiple distance measurements to calculate area or volume.
- Addition Measurement: The device supports adding multiple measurements.
- Interruptor de unidades: Use the appropriate button to switch between metric (m) and imperial (ft/in) units.
Note: Ensure there are no objects positioned within the measurement area that could obstruct the ultrasonic waves. This function is for rough measurements and may not be as precise as laser distance measurement.
Mantemento
- Manteña o dispositivo limpo e seco. Limpe cun pano suave e seco.amp pano. Non use produtos de limpeza ou disolventes abrasivos.
- Retire a batería se non vai usar o dispositivo durante un período prolongado para evitar fugas.
- Store the device in its protective carrying case in a cool, dry place.
- Regularly check the contact pads for wear and ensure they are clean for accurate detection.
Resolución de problemas
- Lecturas inexactas: Ensure the wall surface is dry. High moisture levels can interfere with electromagnetic fields and cause false readings. Re-calibrate the device on a clear section of the wall.
- Sen detección: Verify that the correct mode (STUD, AC WIRE, or METAL) is selected. Ensure the scan button is continuously pressed during scanning.
- Ultrasonic Measurement Errors: Confirm there are no obstructions between the device and the target surface. The ultrasonic function works best on reflective surfaces.
- Laser Not Visible/Level: Check the battery level. Ensure the device is placed on a stable, level surface or adjusted using the plastic flip for leveling.
