Key Function
ON/MODE
Function 1
Switch on CLINOBEVEL 2.
Pushing the key ON/MODE to switch on the inclinometer, all icons on the screen are showed. As
soon as releasing the key of CLINOBELVEL 2, the display switches to « Measure ». The current
angle will be showed in the last used measuring unit. In case of interference, an error message
will appear.
If the key ON/MODE is pushed for more than 3 seconds, the display starts blinking and the au-
tomatically blockage is rescinded. In normal mode, the inclinometer stops automatically after
5 minutes without pushing a button. Exception: In case the inclinometer is externally (cable)
connected, it will never switch off automatically.
Function 2
The key ON/MODE can be used as well to commande the cursor on the bord of the screen. Push
several times on the key in order to get to the desired position.
Function 3
To switch off CLINOBEVEL, keep pushed the key at least 3-4 seconds.
Function 4
Reset of the save-function « REL ZERO ». In case a value is showed, it can be reset to 0 by pushing
the botton ON/MODE. By pushing ENTER you confirm this operation and reset the inclinometer
to 0.

6 Display settings
Before your start measuring with your electro-
nic inclinometer, be sure your settings are made
according to your inspection job. There are
three types of initial settings and one further
temporary setting of display. With respect to
this, continue reading the next pages.
It is advisable to check your settings at regular
intervals, but in any case after the instrument
was not used for a long period of time or ex-
posed to a severe impact. Should any correction
be needed, proceed as described thereafter.
So as to get the best results – i.e. to achieve the
lowest deviation from the theoretical zero – the
following precautions should be taken:
Initial display setting on the centre of gravity through a reverse measurement (See chapter 6.2)
– Function mode « ABSOLUTE »
1. Reverse measurement 2. Zero-setting
6.1 Summary of the possible display settings
– Carefully clean the two measuring faces and
the surface plate as well.
– If your display settings are based on the
centre of gravity, align the reference face as
much as possible.
– If necessary, wait until the temperature
between the inclinometer and the reference
surface has stabilised. This is a relevant
condition for reliable measurements.
– Switch the instrument on preferably before
beginning your dsplay settings and leave it at
rest on the surface plate for a few minutes.
Absolute zero-point: CLINOBEVEL 2 displays
the value « 0 » if the ground measurement of the
inclinometer is connected and precisely poin-
ting the geocenter. (Procedure 6.2)
Virtual zero-point: CLINOBEVEL 2 displays the
value « 0 » for each defined position.
(Procedure 6.3 et 6.4))

Initial display setting on the centre of gravity through a reverse measurement, then in a given
angle α(ZERO-OFFSET function) (See chapter 6.3)
Mode « ABSOLUTE »
Initial display setting on a given reference surface (See chapter 6.4)
– Function mode « ABSOLUTE »
1. Reverse measurement 2. Zero-setting in ZERO-OFFSET mode
Notes:
– The reference against the centre of gravity is
ignored.
– (Zero) setting that might be based on the centre
of gravity is lost.

11
Temporary zero-setting based on a given correction value (angle α) with reference to the initial
setting (ZERO-OFFSET function) (See chapter 6.5)
– Function mode « REL ZERO »
Temporary display setting to zero based on a given reference surface (See chapter 6.6)
– Function mode « REL ZERO »
Notes:
– The initial display setting based on the centre of
gravity allows a temporary zero set in any angular
position.
– Any initial (zero) set stored in the memory
remains unchanged.
Notes:
– The reference against the centre of gravity is
ignored.
– Any initial (zero) set stored in the memory
remains unchanged.
– Function mode « ABSOLUTE »
Absolute zero point setting by rotary measurement
This setting is based on a stable, highly reliable
and moreover, free of charge measuring base
– the centre of the earth. Gravitation is used to
measure the position of the pendulum against
the measuring faces mounted on the instrument
body.
6.2 Initial display setting on the centre of gravity through a reverse measurement
For this operation, two measurements are taken
at the same spot but in opposite di-rections
whilst display is being set. This is called a « re-
verse measurement ».
