Operation - Bosch Professional D-tect 200 C Original Instructions Manual

The accuracy and detection depth of the measuring result may be negatively af-
u
fected if the condition of the substrate is unfavorable.
For the signal test, which checks whether the measuring tool is receiving a faulty signal,
the conductivity criterion and level are used that are defined in ETSI TS 103 361
(V1.1.1) section 9.4.1 for an object depth of d = 60 mm.

Operation

Protect the measuring tool from moisture and direct sunlight.
u
Do not expose the measuring tool to any extreme temperatures or variations in
u
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 exposed to
extreme temperatures or variations in temperature.
Avoid hard knocks to the measuring tool or dropping it. After severe external influ-
u
ences and in the event of abnormalities in the functionality, you should have the
measuring tool checked by an authorised Bosch after-sales service agent.
Certain ambient conditions fundamentally impair the measuring results. These
u
include, e.g. the proximity of devices that generate strong electric, magnetic or
electromagnetic fields, moisture, metal building materials, foil-laminated insula-
tion materials or conductive 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.
Hold the measuring tool by the intended gripping surface (11) only, so as not to
u
influence the measurement.
Do not attach any stickers or labels to the sensor area (19) on the rear of the
u
measuring tool. Metal labels in particular will affect measuring results.
Do not wear gloves when taking measurements and make sure
that you are properly earthed. If you are not properly earthed, the
material identification of "live" wires may be impaired.
When taking measurements, avoid devices that emit strong elec-
tric, magnetic or electromagnetic fields. If possible, deactivate all
tools whose radiation could interfere with the measurement and
switch off the corresponding functions or tools.
