4 Reference Level
The inclinometer has a mounting reference angle
(black line) for an optimal mounting, which is
parallel to the x-axis. This reference angle must be
placed exactly parallel to the object to be
measured, to prevent or minimize any mechanical
offset/cross sensitivity.

5 Mounting and Installation Instruction
The inclinometer is designed for a horizontal
mounting, i.e. the base plate of the inclinometer
with the three mounting holes needs to be placed
on the horizontal plane of the object to be
measured. It can be mounted with M4 screw or
smaller.
5.1 Installation
Prior to installation, please check for all connection
and mounting instructions to be complied with.
Please also observe the general rules and
regulations on low voltage technical devices. Avoid
shock and vibration during installation, as these
5.2 Measurement
The measurement of the tilt angle of the single
measurement axis is carried out over the
respective longitudinal and lateral axis of the

sensors that base on a fluidic measurement
principle are optimal for static measurements and
suitable to only a limited extent of dynamic
measurement.

7 Serial Interface RS 232
Communication with the sensor is done through a
standardized RS-232 interface. Data transmission
is effected in duplex mode. The baud rate is fixed
by 9600 baud. After Power On the sensor is
sending continuous the angle values in degrees
(°). In the setup level several settings can be
permanently modified. If the continuous mode was
permanently changed to the polling mode, the
sensor will send after Power On a start information
with actual parameters. On error no angle values
are sending and after Power On an error message
was add to the start information.

8 Programming Instructions
8.1 Basic Settings
After Power On, the sensor is in the user level. In
factory setting (=Free running mode) every 100ms
the current angle values are continuously supplied
with a baud rate of 9600 bd. In the Setup-level
several settings can be changed permanently such
as query or free running mode, output rate, baud
8.2 Interface parameter
- 9600 Baud , 8 data bits, parity even, 1 stop bit,
The baud rate can be adjusted to different values in the Setup-level.
Structure:
rate and angle offset. If query mode instead of free
running mode is selected, the sensor will send
start information with the current settings after
Power On. In case of errors no angle values will be
provided and after Power On an error message will
be added to the start information.
Baud rate: 9600 Baud (factory setting, changes in Setup-Mode possible)

9 Commands in User Level
1) In free running mode measurement data is continuously displayed. In query mode measurement and display is only once on
command.
2) After reset or new Power On after an interruption of power supply, the sensor will be in user-level again with the original setup or with
the setup changed in the setup level.
3) Only possible in query mode (=free running mode deactivated).
4) The Input of „prog“ must take place within 20 sec.

4) for Code transmission rate see
5) Table 1 <Code transmission rate>
6) for Code baud rate see Erreur ! Source du renvoi introuvable.
Attention! A reset of the baud rate to a default value is not possible. If the user forgets the adjusted baud rate, the new value must
be detected by testing.
7) this instruction is only effectual at sensors with switch output,
8) <switch angle>: three digits from “001” until “300” for the angle in tenths of a degree, max working range of the sensor. Default value
is 025 == 2,5°
9) <hysterese>: two digits from “01” until “99” for the stitching hysterese in tenths of a degree, max working range of the sensor, Default
value is 01 = 0,1°
10) Formulas for Filter :
- Moving Average Filter „M1“, „mm“ (possible values mm = 02 to 40, with mm = 00 is moving average filter deactivated): Output
value = Average over last mm values.
- Exponential Filter „M2“, „tt“ (first order low pass filter, possible values tt = 02 to 40, with tt = 00 is exponential filter deactivated):
Output value = ( old output value * (tt-1) / tt ) + (value / tt )
