7. Operation
7.1. Switching on/off
On:
Press the “On/Off switch / Display light” to switch on the gradient module.
Off:
Press the “On/Off switch / Display light” for at least 2 seconds to switch off the gradient module.
7.2 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 off automatically after 5 minutes, as soon as the device is no longer being moved.
7.3 Display light
1. Switch on the gradient module (display light is active)
2. Press the “On/off switch / Display light” to switch the light on and off.
7.4 Acoustic signal
The acoustic signalling is switched on by pressing the “On/off 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
from the display.
7.5 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.
7.6 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.
