Grade measurement/digital spirit level
Select the inclination measurement/digital spirit level
The measuring tool automatically switches between two
states.
The digital spirit level is used to check the hori-
zontal or vertical alignment of an object (e.g.
washing machine, refrigerator, etc.).
1° 2° 3°
When the inclination exceeds 3°, the ball in the
display lights up red.
The bottom of the measuring tool is used as
the reference level for the digital spirit level.
Grade measurement is used to measure a
slope or incline (e.g. of stairs, railings, when
fitting furniture, laying pipes, etc.).
88.0°
The left-hand side of the measuring tool serves
as the reference level for grade measurement.
If the display flashes during measurement, the
measuring tool has been tipped too heavily to the side.
Memory functions
The value or end result of each completed measurement is
automatically saved.
Tip: When the camera is switched on, the photo is saved
automatically, together with the measuring result. The fol-
lowing information is printed on the photo:
– Measuring result
– Individual measurements (required to determine the
measuring result)
– Measuring function used
– Reference
– Date and time
– Tilt angle (only with spirit level switched on).
If the photo is intended to be used for documentation pur-
poses and transferred via micro USB cable, we recommend
disabling the zoom function.
When the measuring tool is connected to an end device by
micro USB cable, a csv file with all saved measured values is
additionally created.
Memory value display
A maximum of 50 values (measured values or photos with
measured values) can be retrieved.

the newest value is in position 50 (when 50 memory values
are available). When a further value is saved, the oldest
value in the memory is always deleted.

Bluetooth® interface
Transmitting data to other devices
The measuring tool is fitted with a Bluetooth® module which
enables wireless data transfer to certain mobile devices with
a Bluetooth® interface (e.g. smartphone, tablet).
Information about the system requirements for a Bluetooth®
connection can be found on the Bosch website at
www.bosch‑pt.com
Further information can be found on the Bosch
u
product page.
When transmitting data by means of Bluetooth®, time lags
may occur between the mobile device and the measuring
tool. This can be due to the distance between the two
devices or the measurement object itself.
