11
NOTE
is device produces and uses radio-
frequency energy and can also emit it.
If it is not installed and used according
to the instructions, it may cause harmful
interference to radio communication.
However, there is no guarantee that
interference will not occur in a particular
installation.
If this equipment does cause harmful
interference to radio or television
reception, which can be determined by
turning the equipment o and on, the

have been installed correctly in the device.
Inserting batteries
1. Open the battery compartment cover.
2. Insert battery making sure that the poles
of the battery are in the right position.
3. Close the battery compartment cover.
Only use type AA batteries!
Remove the batteries if the instrument is not
used over a longer period of time.
6. Operation
6.1 Switching On/O
On:
Press the “On/O switch” to switch on the
gradient module.
O:
Press the “On/O switch” for at least 2 seconds
to switch o the gradient module.
6.2 Display
If the spirit level is used in the inverted position
(upside down – above your head), the display
screen turns too so that the measurement can
be read easily.

13
e display switches o automatically aer
5 minutes, as soon as the device is stationary.
6.3 Acoustic signal
Press and hold the "Mode button" for 2 seconds
to activate/deactivate the sound signal (signal at
0 °and 90 °). e closer the spirit level gets to the
standard position, the more rapid the frequency
of the acoustic signal.
is function assists you with levelling work,
where it is not possible for you to read the
measurement from the display.
6.4 Hold function
e current measurement is frozen by pressing
the “Hold function” once.
A previously measured value can be “frozen”
on the display using this function.
e measurement remains unchanged until
the “Hold function” button is pressed again.
6.5 Toggling between ABS and INC
You can toggle between ABS (absolute) and
INC (incremental) by pressing the “Hold function”
for more than 2 seconds.
In “ABS” (absolute) mode, the measurement
result is displayed based on the device calibration.
In contrast, in “INC” (incremental) mode,
the measurement result is displayed based
on a relative reference level.
For example, you can take a measurement on a
5° inclined plane in “ABS” mode and then toggle
to “INC” function. In doing so, the measurement
display is set to 0°. You can now take additional
measurements based on this new zero value.
To leave “INC” mode, press the button again for
2 seconds.
6.6 Changing measurement display
• Press the "Mode button" to switch between
units; ° / mm/m / % / in/.
6.7 Changing the display resolution
Press the “Hold function” and the “On/O switch /
Display light” button at the same time to change
the resolutions between: 0.00° and 0.0°.
6.8 Bluetooth
Fast and ecient data transfer of measured
values can be made directly to a smartphone
via Bluetooth.
NOTE
To pair with a smartphone,
launch the Hultafors measures
app and connect using one of
the function options.
