2 PRESENTATION
2.1 General
description
TESA CLINOBEVEL are electronic inclinometers specially designed for direct
measurement of any angle of inclined surfaces up to ± 60°. Since they make use of the
force of gravity, these instruments also serve as precision levels for accurate levelling on
machines, devices etc. Both measuring faces that are arranged horizontally and vertically
on the solid instrument body serve as resting points on the inclined surface to be inspected.
Due to their possible orientation in any direction, every TESA CLINOBEVEL is also suited
for comparative measurement where the difference between both values obtained from
two successive measurements is shown on the display. In addition, these electronic
inclinometers also permit straightness and flatness inspection of scales, surface plates or
machine parts through single measurements performed step by step according to a
defined grid combined with value processing.
Providing ease of handling, TESA CLINOBEVEL 3 is the favourite for checking horizontal
and vertical surfaces.
TESA CLINOBEVEL 3 is available with 3 measurement zones: ±1°, ±10°, ±60°.
TESA CLINOBEVEL 3 with the measuring ranges ±10° and ±60° is available in cast iron
and aluminium.
The version with the measuring range ±1° is only available in cast iron and its measuring
bases on the left and bottom are precisely scraped.
The TESA CLINOBEVEL 3 allows wireless data transmission to an
Android device. The app can be downloaded from the Play Store.
Various parameters can be set and changed in the TESA CLINOBEVEL 3 like
- Various colour profiles
- Various display methods, including bar graphs or precision levels
- Measuring mode
etc.
can be set and changed.
The TESA CLINOBEVEL 3 contains a high-precision inclination sensor which is
optimized for the measuring range of the instrument. The measuring principle of this
sensor is based on the deflection of a membrane suspended between two electrodes,
which functions as a pendulum. The membrane builds a differential capacitor with the two
electrodes.
Inclining the sensor respectively the measuring instrument moves the pendulum which
changes the capacities. This change of capacities is used as the primary signal for the
calculation of the inclination angle. The system is insusceptible to external
electromagnetic influences. In the TESA CLINOBEVEL 3 this primary signal is
transformed into an inclination value basin

6.7 Care of the
batteries
Make sure that the batteries are inserted properly. Follow the symbols showing you the
correct way to position the POSITIVE (+) and NEGATIVE (-) ends of the batteries. Keep
battery contact surfaces clean by gently rubbing with a clean pencil eraser or cloth. Remove
all used batteries from the device at the same time, then replace them with new batteries of
the same size and type. Store batteries in a cool, dry place at normal room temperature.
Remove batteries from devices that will be stored for extended periods. Don't dispose of
batteries in a fire - they may rupture or leak. Don't recharge a battery unless it is specifically
marked "rechargeable."
Operating temperature (min/max): 0°C to +40°C
relative humidity: max. 85%

7 FUNCTIONS
7.1 Functions List
Selection
The TESA CLINOBEVEL 3 offers a wide range of functions and adjustment possibilities.
The list of functions appears when the key is pressed. With the keys
the desired function can be selected and with it will
be started. If during 10 seconds no further key is operated, the function list will be left. With
the key a function selected can be abandoned. Already entered changes
of parameters will be rejected and the TESA CLINOBEVEL 3 will return to the previously
used display mode.
Here after the sin
g
le functions will be described.
7.2 Set absolute zero Absolute Zero means that the instrument shows the measuring value "0" if the measuring
surface of the instrument is aligned exactly according to gravity.
The absolute zero is used as the base for absolute inclination measurements. In order to
achieve the best possible precision please observe that the measuring object (support) and
the TESA CLINOBEVEL 3 have the same temperature and that the instrument is in operation
for several minutes before starting a measurement. Mark the precise position and particularly
the direction of the TESA CLINOBEVEL 3 in order to be able to turn the instrument by 180
degrees and to put it in opposite direction at the very same spot.
The absolute zero will be determined from a
reversal measurement (two measurements
in opposite direction but at the same spot).
Use for this procedure an adequate surface
(rigid and stable support, as flat as possible
and as horizontal as possible), where you
put the TESA CLINOBEVEL 3. Mark the
position and the direction of the TESA
CLINOBEVEL 3 precisely and turn it on the
same spot by 180 degrees.

During the measurement the display will graphically show
the current measurement.
Complete the measurement with the key
or with the remote control. After 15 seconds the measuring
value will automatically be read.
After a successful reading of the first measuring value the
position of the instrument for the second measurement will
appear in the display.
Put the TESA CLINOBEVEL 3 to the second position (turn
the instrument by 180 degrees in the horizontal).
Start the second measurement as well pressing the key
or with the remote control.
During the measurement the display will graphically show
the current measurement.
Complete the measurement with the key
or with the remote control. After 15 seconds the measuring
value will automatically be read.
After termination of the reversal measurement the display
for the actual measurement under consideration of the
ZERO OFFSET will appear on the screen.
The value of the “Zero-Offset” determined by a reversal measurement
corresponds to the deviation of the zero point of the TESA CLINOBEVEL 3
compared to the absolute Zero. The displayed measuring value
corresponds to the value of the TESA CLINOBEVEL 3 minus the Zero-
OFFSET.
Value displayed = Value of the TESA CLINOBEVEL 3 - “Zero-Offset”
The reversal measurement described above should be repeated periodically in order to
achieve a high measuring precision, particularly when the TESA CLINOBEVEL 3 has not been
in use for a longer period.
