Digital detector
– BRA
A) Depends on material and size of the objects, as well as material and condition of the substrate
B) For a copper pipe with a 15 mm diameter
C) For reinforcing steel with a 12 mm diameter
D) Lower detection depth with non-live wires
E) Only non-conductive deposits occur, whereby occasional temporary conductivity caused by
condensation is expected.

The serial number (19) on the type plate is used to clearly identify your measuring tool.
The accuracy and detection depth of the measuring result may be negatively af-
u
fected if the condition of the substrate is unfavorable.
Measuring Tool Power Supply
The measuring tool can be operated either with a Bosch lithium-ion battery pack (12),
with commercially available non-rechargeable batteries or with commercially available
NiMH rechargeable batteries.
Note: Never store the measuring tool without an inserted battery compartment
cover (16) or lithium-ion battery pack (12), particularly in dusty or humid environments.
The battery charge indicator (d) will indicate the state of charge of the lithium-ion bat-
tery pack (12), non-rechargeable batteries or NiMH batteries on the display.
Operation with Lithium-Ion Battery Pack
Inserting/Replacing a Lithium-Ion Battery Pack
To switch from non-rechargeable or NiMH batteries to a lithium-ion battery pack (12),
press on the locking mechanism (15) of the battery compartment cover. Remove the
battery compartment cover (16) and the inserted non-rechargeable or rechargeable bat-
teries.
Insert the lithium-ion battery pack (12) and let the locking mechanism (11) click into
place.
To remove the lithium-ion battery pack (12), press the locking mechanism (11) and take
the lithium-ion battery pack out of the measuring tool.
Charging a Lithium-Ion Battery Pack
For charging, use the recommended USB power supply unit or a USB power sup-
u
ply unit whose output voltage and minimum output current comply with the re-
