• depending on material and size of the objects as well as material and condition of the base material (walls, ceilings, floors) ** less scanning depth for wires/conductors that are not “live” In terms of accuracy and scanning depth, the measurement result can be infe- rior in case of unfavourable surface quality of the base material. The measuring tool can be clearly identified with the serial number 6 on the type plate.

Do not subject the measuring tool to extreme temperatures or var- iations in temperature. As an example, do not leave it in vehicles for a long time. In case of large variations in temperature, allow the meas- uring tool to adjust to the ambient temperature before putting it into operation. In case of extreme temperatures or variations in tempera- ture, the accuracy of the measuring tool can be impaired. Avoid heavy impact to or falling down of the measuring tool. Switching On and Off Before switching the measuring tool on, make sure that the sensor area 7 is not moist. If required, dry the measuring tool using a soft cloth. To switch on the measuring tool, slide the On/Off switch 3 downwards. After a short self-test, the tool is ready for use. The readiness of use is indi- cated when the signal LED 2 illuminates. If the signal LED 2 fails to illumi- nate after switching on the tool, you must replace the batteries. To switch off the measuring tool, slide the On/Off switch 3 upwards. When no measurements are carried out for approx. 10 minutes, the measuring tool switches off automatically in order to extend the service life of the batteries. Note: The on/off switch 3 will remain in the “on” position when the measuring tool switches itself off automatically. To switch the measuring tool back on, switch it off first before switching it on again.

Detecting Metal Objects After switching on, the signal LED 2 lights up green. Position the measuring tool on/against the surface being detected and move it sideways. – If no metal object is visible in the base material, then the signal LED 2 continues to illuminate green and no signal tone sounds. – When the measuring tool comes closer to a metal object, the signal LED 2 first lights up yellow and changes to red the closer it comes to the metal object. As soon as the signal LED lights up red, a signal tone is also emit- ted, the pitch of which rises the closer it comes to the metal object. – Over a metal object, the signal LED 2 illuminates red and a signal tone is emitted at maximum pitch. Even with a yellow signal LED 2, a metal object may be located be- low the sensor area. Small or low-lying metal objects are located in the vicinity of the sensor or the wall material impairs the measurement results. Signal LED Explanation green no object detected yellow – metal object in the vicinity of the sensor – small or low-lying metal object within the sensor area or – impairment of the sensor due to unfa- vourable wall material red and continuous tone metal object detected in the sensor area red flashing (fast) and intermittent sound “live” wire/conductor detected OBJ_BUCH-2841-002.book Page 20 Thursday, August 4, 2016 6:22 PMEnglish | 21 Bosch Power Tools 1 609 92A 3FC | (4.8.16) After moving over the surface the first time, the posi- tion of the metal object is only roughly indicated. If you move the measuring tool over the metal object several times, the object detection will become increasingly precise. After moving over the metal object several times (without lifting the measuring tool from the base material), its position can be indicated very accu- rately: if the signal LED 2 illuminates red and the signal tone sounds, the metal object is below the sensor area. When the pitch of the signal tone is highest, the metal object is located below the centre of the sensor. Scanning for “Live” Wires The measuring tool indicates wires, which carry voltage between 110 V and 240 V and a frequency corresponding to the widely used standard (AC with 50 or 60 Hz). Other wires (carrying DC, higher/lower frequency or voltage) as well as non-“live” wires/conductors cannot be found relia- bly, but are possibly indicated as metal objects. The detection for “live” wires/conductors takes place automatically with every measurement. When a “live” wire/conductor is detected, the signal LED 2 flashes red and an intermittent signal tone sounds with rapid tone sequence. Move the measuring tool repeatedly over the surface to locate the “live” wire/conductor more precisely. After moving over the surface several times, the position of the “live” wire/conductor can be indicated very accurately. It is easier to find live cables if electricity consumers (e.g. lights, appliances) are connected to the cable being searched for and are switched on. Switch off electricity consumers before drilling, sawing or milling into the wall. Note: Always ensure that you hold the measuring tool firmly without gloves to enable a good grounding. Also ensure that ladders/scaffolding must be grounded. Avoid ladders/scaffolding whose supports have plas- tic caps underneath them. Do not wear insulating footwear. It may not be possible to find live cables in certain conditions (e.g. behind metal surfaces, behind surfaces that are very dry or very damp). If the in- dicator LED 2 lights up yellow or red over a large area, the material is elec- trically shielded and you will not be able to find live cables accurately.

This will enable you to obtain more accurate measure- ment results. Marking Objects Detected objects can be marked as required. The outer edges of an object are indicated by the colour change of the signal LED 2 from yellow to red. The centre of the metal object can be determined by the pitch. Using a pen, mark the sought after location at the top and the side marker aids 1. Continuous Flashing Green/Yellow/Red If the signal LED 2 flashes alternately green, yellow and red, even when no metal object or no “live” cable is in the vicinity, the measuring device must be sent in for service. Maintenance and Service Manual Calibration If the signal LED 2 illuminates red or yellow, even when no metal is in the vicinity of the measuring tool, the tool must be recalibrated. – To do this, switch the measuring device on using the On/Off switch 3. – Remove a battery from the switched on measuring device. – While the battery is removed, switch the measuring device off using the On/Off switch 3. – Reinsert the batteries into the measuring device (pay attention to the polarity!). – Now remove all objects in the vicinity of the measuring device (includ- ing wrist watches or rings of metal) and hold the measuring tool up in the air. – Switch the measuring device on using the On/Off switch 3 and off again within 3 seconds. The signal LED 2 of the measuring device will flash red in slow succession during the 3 seconds to indicate that it is ready to calibrate. – Switch the measuring device back on within 0.5 seconds. The calibra- tion is initiated and takes about 6 seconds. The signal LED 2 will flash green for 6 seconds in quick succession, the calibration is being per- formed. Now the device is once more ready for operation and the signal LED 2 illuminates solid green.
