Power Cable

The operating mode 

“Power cable”

 is suitable only for de-

tecting "live" conductors (110 – 230 V). 
Press button

 to activate the operating mode 

“Power cable”

. 

The illuminated ring

green.
When a “live” conductor is detected, indication 

f

 appears on 

the display 

3

. Move the measuring tool repeatedly over the ar-

ea to localise the “live” conductor more precisely. After mov-

ing over the “live” conductor several times, it can be indicated 

very accurately. When the measuring tool is very close to the 

conductor, the illuminated ring 

1

 flashes red and the audio 

signal beeps swiftly.

Notes: 

– “Live” conductors are indicated in any operating mode.

– “Live” conductors can be detected easier when power con-

sumers (e. g. lamps, machines) are connected to the 

sought conductor and switched on.

–

Under certain conditions (such as below metal surfaces 

or behind surfaces with high water content), “live” con-

ductors cannot be securely detected.

 The signal 

strength of a “live” conductor depends on the position of 

the cable. Therefore, apply further measurements in close 

proximity or use other information sources to check if a 

“live” conductor exists.

– Voltage-free conductors can be detected as metal objects 

in the operation mode 

“Metal”

. This does not apply for 

stranded conductors (contrary to solid conductors or 

cable).

– Static electricity can lead to inaccurate indication of elec-

tric lines, e. g., over a large range. To improve the indica-

tion, place your free hand flat on the wall next to the meas-

uring tool, in order to remove the static electricity.

Working Advice

f

Measuring values can be impaired through certain am-

bient conditions. These include, e. g., the proximity of 

other equipment that produce strong magnetic or elec-

tromagnetic fields, moisture, metallic building materi-

als, foil-laminated insulation materials or conductive 

wallpaper or tiles. 

Therefore, please also observe other 

information sources (e. g. construction plans) before drill-

ing, sawing or routing into walls, ceilings or floors.

Marking Objects

If required, detected objects can be marked. Perform a meas-

urement as usual. Once you have found the boundaries or the 

centre of an object, mark the sought location through the 

marking hole

.

Temperature Control

The measuring tool is equipped with a temperature control indi-

cator, as accurate measurements are only possible as long as 

the temperature within the measuring tool remains constant. 
When the temperature control indicator 

g

 lights up, the meas-

uring tool is not within the operating temperature range or 

was subject to large variations in temperature. 

Switch the 

measuring tool off and allow it to adjust to the ambient 

temperature before switching it on again.

Warning Function

When indicator 

b

 lights up on display 

3

 and indication 

4

 flash-

es above button 

10

, the measurement must be restarted. Re-

move the measuring tool from the wall and place it on the base 

material at a different location.
When indicator 

b

 flashes on display 

3

, send the measuring 

tool in the provided protective pouch to an authorised cus-

tomer services agent.

Recalibration

When measuring indicator 

i

 indicates a continuously high am-

plitude in the operating mode 

“Metal”

, even though there is 

no metal object near the measuring tool, the measuring tool 

can be manually recalibrated.
– Switch the measuring tool off.

– Remove all objects near the measuring tool that could be 

detected, including your wrist watch or rings made of 

metal, and hold the measuring tool up.

Pay attention that battery indicator 

h

 indicates at least 1/3 

capacity: 

Hold the measuring tool in such a manner that the type 

plate 

13

 faces toward the ground. Avoid bright light sourc-

es or direct sunlight from shining on the area 

12

 and 

13

, 

without covering off this area.

– Press and hold buttons 

5

 and 

7

 until the illuminated ring 

1

lights up red. Then release both buttons.

– When the calibration was successful, the measuring tool 

will automatically start after a few seconds, and will be 

ready for operation again.

Note: 

If the measuring tool does not automatically start, 

repeat the recalibration. If the measuring tool still does not 

start, send it in the provided protective pouch to an author-

ised customer services agent.

Maintenance and Service

Maintenance and Cleaning

f

Check the measuring tool each time before use. 

In case 

of visible damage or loose components inside the measur-

ing tool, safe function can no longer be ensured.

Keep the measuring tool clean and dry at all times to ensure 

proper and safe working.
Do not immerse the measuring tool in water or other fluids.
Wipe away debris or contamination with a dry, soft cloth. Do 

not use cleaning agents or solvents.
In order not to affect the measuring function, decals/stickers or 

name plates, especially metal ones, may not be attached in the 

sensor area 

12

 on the front or back side of the measuring tool.

Do not remove the contact pads 

11

 on the backside of the 

measuring tool.
If the measuring tool should fail despite the care taken in 

manufacturing and testing procedures, repair should be 

carried out by an authorised after-sales service centre for 

Bosch power tools. Do not open the measuring tool yourself.
In all correspondence and spare parts orders, please always 

include the 10-digit article number given on the type plate of 

the measuring tool.
