6. Operation
6.1. Switching on/o
On:
Press the “On/o switch / Display light“ to switch on the gradient module.
O:
Press the “On/o switch / Display light“ for at least 2 seconds to switch o the gradient module.
6.2 Display
If the gradient 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.
The display switches o automatically after 5 minutes, as soon as the device is no longer being moved.
6.3 Display light

2. Press the “On/o switch / Display light“ to switch the light on and o.
6.4 Acoustic signal
The acoustic signalling is switched on by pressing the “On/o switch for acoustics“. The closer the
gradient spirit level gets to the standard position, the more rapid the frequency of the acoustic signal.
This function assists you with levelling work, where it is not possible for you to read the measurement

6.5 Hold function
The current measurement is frozen by pressing the “Hold function“ once.
A previously measured value can be “frozen“ on the display using this function. The measurement
remains unchanged until the “Hold function“ button is pressed again.
6.6 Toggling between ABS and INC
You can toggle between ABS (absolute) and INC (incremental) by pressing the “Hold function“ for more

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
