Aligning the measuring tool for calibration:
Align the measuring tool so that the X-axis indicator imprin-
ted on the measuring tool with the "+" side is pointing to the
laser receiver. For this, the X‑axis must be perpendicular to
the laser receiver.
To start calibration:
– For calibration via the Bosch Levelling Remote App:
Switch on the measuring tool. Start calibration in the app.
Follow the instructions in the app.
– For calibration without the app: Switch on the measuring
tool and the laser receiver. Make sure that both of these
are connected via Bluetooth®. Start calibration by press-
ing the on/off button on the laser receiver and the
CenterFind mode button on the laser receiver at the
same time. "CAL" will appear on the display of the laser
receiver.
Press and hold the CenterFind mode button on the laser re-
ceiver to cancel the calibration, if required.
To perform calibration without the app:
In the menu that appears in the meas-
uring tool display after starting calib-
ration, select the existing distance
between the measuring tool and the
laser receiver. To do this, press the ▲
button (4) or the ▼ button (3). Con-
firm your selection with
the slope button (14).
To confirm the selected measuring
distance including the corresponding
levelling accuracy ( ), press the
slope button (14) in the menu which
subsequently appears. To go back to
selecting the measuring distance (
), press the line operation button (5).
Align the height of the laser receiver so that the variable
laser beam (8) on the laser receiver is indicated as
"centred" (see operating instructions for the laser receiver).
Secure the laser receiver at this height.

Check whether the measuring tool and
laser receiver are aligned with each
other, as illustrated on the display
(the "+" side of the X-axis is aligned to
the laser receiver). Start calibration of
the X-axis with by pressing the
slope button (14).
If this step appears on the display, ro-
tate the measuring tool 180° so that
the "–" side of the X‑axis is directed at
the laser receiver. For each rotation,
take care not to change the height and
inclination of the measuring tool. Con-
firm the rotation with by pressing
the slope button (14). Calibration of

To calibrate the Y-axis, rotate the
measuring tool 90° in the direction of
the arrow so that the "+" side of the
Y‑axis is directed at the laser receiver.
Confirm the rotation with by press-
ing the slope button (14).
If this step appears on the display, ro-
tate the measuring tool 180° so that

calibrated with the levelling accuracy
selected at the beginning. End the cal-
ibration with by pressing the slope
