A) Depends on material and size of the objects, as well as material
and condition of the substrate
B) Lower detection depth with non-live wires
C) Only non-conductive deposits occur, whereby occasional tem-
porary conductivity caused by condensation is expected.
The serial number (8) on the type plate is used to clearly identify your
measuring tool.
u
The accuracy and detection depth of the measuring
result may be negatively affected if the condition of
the substrate is unfavorable.
Assembly
Inserting/Changing the Battery
It is recommended that you use alkaline manganese batter-
ies to operate the measuring tool.
To open the battery compartment cover
(9) , push the lock-
ing mechanism (10) in the direction of the arrow and lift the
battery compartment cover. Insert the battery.
When inserting the batteries, ensure that the polarity is cor-
rect according to the illustration on the inside of the battery
compartment.
u
Take the battery out of the measuring tool if you do
not intend to use the tool for a long time.
When it is
stored in the measuring tool for longer periods, the bat-
tery can corrode and discharge itself.
Battery indicator
The battery indicator (g) on the display always indicates the
current battery status:

Operation
u
Protect the measuring tool from moisture and direct
sunlight.
u
Do not expose the measuring tool to any extreme tem-
peratures or variations in temperature. In case of
large variations in temperature, leave the measuring
tool to adjust to the ambient temperature before
switching it on.
The accuracy of the measuring tool and
the functionality of the display may be compromised if ex-
posed to extreme temperatures or variations in temperat-
ure.
u
Avoid hard knocks to the measuring tool or dropping
it.
After severe external influences and in the event of ab-
normalities in the functionality, you should have the
measuring tool checked by an authorised
Bosch after-
sales service agent.
u
Certain ambient conditions fundamentally impair the
measuring results. These include, e.g. the proximity of
devices that generate strong electric, magnetic or
electromagnetic fields, moisture, metal building ma-
terials, foil-laminated insulation materials or conduct-
ive wallpaper or tiles.
Therefore, also refer to other in-
formation sources (e.g. construction plans) before
drilling, sawing or routing into walls, ceilings or floors.
u
Hold the measuring tool by the intended gripping sur-
face (5) only, so as not to influence the measurement.
u
Do not attach any stickers or labels to the sensor
area
(7) on the rear of the measuring tool. Metal labels
in particular will affect measuring results.
Do not wear gloves when taking measure-
ments and make sure that you are properly
earthed.
If you are not properly earthed, the
identification of live wires may be impaired.
When taking measurements, avoid devices
that emit strong electric, magnetic or elec-
tromagnetic fields.
If possible, deactivate all
tools whose radiation could interfere with the
