MultiFinder Plus - Hand tool Laserliner - Free user manual and instructions

USER MANUAL MultiFinder Plus Laserliner

Function/Application Multiple integrated sensors make MultiFinder Plus by Laserliner a highly efficient detecting device for locating metal, finding wall beams and joists in drywall structures and detecting live lines. The MultiFinder Plus is equipped with an VTN display with user guide, ensuring easy and reliable operation. Acoustic and optical detection signals to locate objects facilitates handling and ensures a high level of functional reliability.

Always switch off the power supply when working in METAL- and STUD-SCAN mode in the vicinity of electric conductors.

Calibration Auto-Calibration The automatic calibration is performed in METAL-SCAN and AC-SCAN measurement immediately when the device is switched on and when the measuring mode is switched. Auto-Cal Plus When an object has been found, the device performs another automatic calibration in METAL-SCAN measurement. This simplifies the process of isolating objects to be measured and adjusting the device to different surfaces. metal, wire, object found metal, wire, object is nearby METAL-SCAN and AC-SCAN mode Green: metal or live wire is nearby Red: metal or live wire found STUD-SCAN mode Red: object is nearby Green: object found Symbols Operation Red = Live wire warning Switch on: Briefly press the On/Off button (4). Switch off: Keep the On/Off button (4) pressed for 4 seconds. AutoShutOff: The device will automatically switch itself off about 2 minutes after the last measurement.

Open the battery compartment on the housing‘s rear side and insert a 9 V battery. Correct polarity must be observed. Insert battery13 MultiFinder Plus

Briefly press the Mode button (4). METAL-SCAN: Detecting metal in all non-metallic materials AC-SCAN: Locating live lines directly under non-metallic cladding STUD-SCAN: Detecting wooden wall beams and joists as well as metal in drywall structures under non-metallic cladding The device and the wall must maintain contact during calibration in STUD-SCAN mode and throughout the entire measurement process. A hand should remain at the device the entire time as well.

Manual calibration Pressing the CAL button (5) manually cali- brates the device. This allows measurements to be restarted and objects to be isolated more precisely. Maximum sensitivity is achieved when the device is held in the air while calibrating. This can be useful for METAL and AC-SCAN measurements. The tool is able to detect hidden metal in all non-metallic materials, e.g. brick, concrete, screed, wood, plaster fibre- board, gas concrete, ceramic and mineral building materials. – Select METAL-SCAN (button 4). – As soon as the display switches from CAL to CAL OK, you can move the device. – MOVE: Move the tool slowly across the surface. Measuring in METAL-SCAN mode Select measurement mode GB14

Isolate an object to be measured by passing over it several times. Manual calibration Tip 1: The position between the two markings is the mid-point of the metal object. Through the high measuring sensitivity, thick metal objects appear broader than they are in real life. Therefore move the device over the newly found object as shown in Image B. The device is calibrated automatically during this process. Manual calibration should be performed near the place found last as shown in Image C. Repeat this step as needed. GB15 MultiFinder Plus

Detecting wooden wall beams and joists as well as metal in drywall structures, e.g. under gypsum fibreboard, wood panels or other non-metallic cladding. – Select STUD-SCAN (button 4). – Now follow the instructions on the VTN display. – ON WALL: Place the tool against the wall. – PRESS CAL: Press the calibration button (5) and wait until calibration is completed: CAL OK – MOVE: Move the tool slowly across the surface. Measuring in STUD-SCAN mode Manual calibration Tip 2: The position where you start is important: First place the device in a position where you know there is no metal. Otherwise, the message “ERROR” will appear in the display. To remedy: Move the device to another position a few centimetres away and start measuring again. Tip 3: In the case of complicated applications, e.g. ribbed steel, scan the surface both horizontally and vertically. Tip 4: Flexible floor and wall heating pipes which contain a metal foil and are located near the surface may also be detected. Test for this function in places where you know the position of such pipes. Note: If an object is deep inside a wall, the device may not indicate it clearly. GB16 Special things to note with various materials It may not be possible to detect wooden studs or joists through the following materials: – Ceramic floor tiles – Fitted carpeting with padded backing – Wallpaper with metal fibres or metal foil – Freshly painted, damp walls. These must have dried for at least one week. – In problem cases, use METAL-SCAN to localise nails or screws in dry walls that line up vertically where a stud is located. If electric wires or metal or plastic pipes are located near or in contact with a plaster fibreboard panel, they may be identified by the MultiFinder Plus as studs.

Tip 1: The position between the two markings is the mid-point of the stud. Tip 2: The position where you start is important: First place the tool in a position where you know there is no stud. Otherwise, the message “ERROR” will appear in the display. To remedy: Move the tool to another position a few centimetres away and start measuring again. Tip 3: To avoid interference while scanning, keep your free hand and other objects at least 15 cm away from the MultiFinder Plus. Tip 4: The MultiFinder Plus will only find the outside edge of double studs and headers which may be fitted around doors, windows and corners. Tip 5: Ensure that you have really detected a stud. To do so, check on both sides whether other studs are present at equal distances, usually at 30, 40 or 60 cm. Also check that it is a stud by scanning at several places directly above and below the position of the first find. Tip 6: Textured ceilings: The ceiling must be covered with card- board to protect it. Note: If an object is deep inside a wall, the device may not indicate it clearly. GB17 MultiFinder Plus

Isolate an object to be measured by passing over it several times. Manual calibration

For localising live wires directly beneath the plaster or behind wooden panels and other non- metallic panelling. It is not possible to detect live wires in dry walls with metal studs. – Select AC-SCAN (button 4). – As soon as the display switches from CAL to CAL OK, you can move the device. – MOVE: Move the tool slowly across the surface. AC-SCAN GB18

Always switch off the power supply when working near electric wires.

Tip 1: Manual calibration should be performed near the place found last as shown in Image B/C. Repeat this step as needed. Tip 2: Because of static charges, electric fields may be detected at the side of the actual position of the wire. To carry away these charges, lay your free hand on the wall. Tip 3: Move the tool slowly as friction can generate interfering electric charges. Tip 4: If you suspect that wires must be present but cannot find any, this may be because they are shielded in conduits. Use METAL-SCAN in order to localise conduits. Tip 5: Metal in walls (e.g. metal studs) transmit electrical fields and may therefore cause interference. In this case, switch to METAL-SCAN in order to find the wire. Tip 6: The position where you start is important: To achieve maximum sensitivity, start by placing the device in a position which is known not to be near live wires. Wires which are at a depth of more than 4 cm may not be detected.

Continuous current monitoring in unshielded wires as soon as an electrical field is detected. STUD-SCAN / METAL-SCAN Current monitoring The device features backlighting. GB19 MultiFinder Plus
