1. INTRODUCTION
1.1. Principal description of the LEVELMETER 2000
The LEVELMETER 2000 was designed by WYLER AG, Switzerland as an intelligent display and measuring unit
in connection with the digitized sensor family ZEROTRONIC. It is also used as a display device for the electronic
inclinometers MINILEVEL and LEVELTRONIC "NT". Besides the excellent measuring performance the specialty
of the ZEROTRONIC as well as the "NT" family instruments is the use of the digital technology. This allows
transmitting the measuring signals over long distances without any loss of accuracy.
With the LEVELMETER 2000 all the sensors and instruments of the ZEROTRONIC and the "NT" family
instruments may be used. (See point 1.3. Possible configurations (instruments and sensors connections)
The LEVELMETER 2000 is a
- Display unit
- Interface between Measuring instrument and PC
- Control unit for calibrating (ZEROTRONIC sensors only) and identifying/addressing the
connected sensors and instruments
On the LEVELMETER 2000 the following parameters may be set or changed:
- Measuring unit
- Sensor address/port
- Type of damping filter
- Base length relative and many more
The LEVELMETER 2000 is fully interchangeable with the other ZEROTRONIC components. This means that the
LEVELMETER can be exchanged if necessary by any other family type instrument. All the relevant data, such as
- Calibration data
- Sensor address
- ZERO point etc.
are stored at the respective sensor heads. Through the RS 232 port the measuring data may be transmitted to a
PC/Laptop or to an other outlet as well as to the Measuring software LEVELSOFT of WYLER’s.
The measuring principle of the ZEROTRONIC family is based on a changing of the capacity of a condenser built
of two electrodes and a pendulum in form of a shield installed in between. The measured change of capacity is
directly influenced by the change of the inclination of the pendulum. This capacity change is the primarily used
signal for the angle to be measured. The measuring system is designed to be completely antimagnetic. The basic
signal received in the LEVELMETER 2000 will be computed into an angle by comparing the signal with a
reference curve stored and then displayed in the required unit.
1.2. Starting
Before working with the LEVELMETER 2000 it is strongly recommended to carefully read this manual
first.
This will avoid malfunctioning by making unsuitable manipulations like e.g. deleting the calibration date in the
sensor heads etc.

1.3. Possible configurations (instruments and sensors connections)
Possible connections of sensors and instruments:
ZEROTRONIC sensors
Inclination measuring instrument + CLINOTRONIC PLUS +
Inclination measuring instrument MINILEVEL NT Inclination measuring instrument LEVELTRONIC NT
All the displayed configurations are possible. For individual specifications see the respective data sheets.
On both of the ports ( A & B) up to 31 sensors/instruments may be connected.
This manual covers mainly the combination of the LEVELMETER 2000 with ZEROTRONIC sensors. For
other possible combinations such as together with the instruments MINILEVEL and LEVELTRONIC NT
please refer to the respective manuals.

2.1.2. Mounting of the sensors / codes
The following points must be observed:
2.1.2.1. Correct horizontal position
Sensor-Type
Codes:
XA-XXX Sensor type 1 Arcdeg.
XB-XXX Sensor type 5 Arcdeg.
XC-XXX Sensor type 10 Arcdeg.
XD-XXX Sensor type 30 Arcdeg.
XE-XXX Sensor type 60 Arcdeg.
The sensors are to be mounted so that the reading at the flange horizontally correct. The meaning of the coding is
the following.
The sensor measuring range is marked with the letters A to E. The other numbers are part of the identification
code
2.1.2.2. Angular position
The positive or negative inclination is according to the following definition (Looking at the sensor with the cable
connector to the right):
Inclination: positive
Inclination: horizontal (0 Degree)
Inclination: negative
ATTENTION / IMPORTANT for measurements with ZEROTRONIC sensors
For precise measurements it is important that the sensors have been in operation for at least 15 minutes (start
up time) before the first measurement with a LEVELMETER 2000.
After putting it in function the sensor is slightly heated up by some of the built-in electronic components. After the
start-up time mentioned above the system is stabilised and ready for measurements.
Disabling the automatic shut-off of the LEVELMETER 2000
When pressing the ON/MODE key for more than 3 seconds the display starts flashing and the automatic shut
off is disabled. In the standard mode the instrument shut off after about 10 minutes.
Exeption: In case the LEVELMETER 2000 is powered by a connection to a mains adapter, the instrument is
never shutting off automatically.

2.2. Panel/Functions
2.2.1. Description of the key functions
ON/MODE - Key
Function - 1 - Pressing the ON/MODE key starts the LEVELMETER 2000. When keeping the key
pressed all the LCD elements are lighted. After releasing the key the instrument
switches to the measuring mode if a sensor is connected and the calibration data of this
sensor has been collected. After a short period of time the actual angle will be displayed
in the last used measuring unit. In case of trouble an error message will be displayed.
(See point 5)
Disabling the automatic shut-off of the LEVELMETER 2000
When pressing the ON/MODE key for more than 3 seconds the display
starts flashing and the automatic shut off is disabled. In the standard mode the
instrument shut off after about 10 minutes.
Exeption: In case the LEVELMETER 2000 is powered by a connection to a
mains adapter, the instrument is never shutting off automatically.
Function - 2 - The ON/MODE is also used for moving the selection pointer on the lower display
area. By pressing this key the selection pointer moves from one position to the next.
Function - 3 - For shutting off the LEVELMETER 2000; the ON/MODE key needs to be pressed for
a few seconds until the displayed figures disappear. If the key is pressed min.
15 seconds a date and a 4 digit number appears. This is the status of the software
release of the Levelmeter.
Function - 4 - Used for „ZERO-Setting“ of saved (memory) values in the functions „REL ZERO“ and
„ZERO“ To set the memory in these two functions to ZERO press the ON/MODE
key, the displayed values will become ZERO. This has to be confirmed by pressing
ENTER
ENTER – Key
The key ENTER is used to save an entered value or to accept a selected function.
When using the Software LEVELSOFT the key <ENTER> has the identical function
as the push button of the connecting cable (Dongle cable) or the push button of the
infrared sender unit for data collection.
SEND/ESC- Key
Function - 1 - The key SEND is used for the transmission of a measuring value through the RS232
port or to send the value to a printer or another connected system. Through the same
port the values may also be transmitted to a PC or Laptop for further treatment of the
data.
Function - 2 - Also used for canceling any „HOLD“ function and return to the measuring mode.
Function - 3 - Canceling any task not yet finished.

ZERO/SELECT "+/-" - Key
Function - 1 - The key ZERO/SELECT "+/-" can be used to change a number of possible
parameters like e.g.
- Measuring units
- Measuring units, respectively ports ( „A“ / „B“ / „A+B“ / „A B“ )
- Changing of the measuring range
- Changing of the instruments address
- Set up the relative base length
- Set up of the „Zero-Offset“
- Set up of the „REL Zero-Offset“ etc.
Function - 2 - In the mode „A B“ the measured value of the instruments connected on Port “A” and
Port “B” are displayed alternatively. The changing speed is depending on the Baud rate
of the connected instrument.
(MINILEVEL / LEVELTRONIC change time is approx 8 seconds, ZEROTRONIC
sensors change time is approx 4-5 seconds)
The alternating display can be stopped and the instrument’s value connected to port “B”
is constantly seen when the key ZERO/SELECT "+" is pressed.
to change to the value of the instrument connected to port “A” the key
ZERO/SELECT "-" must be applied.
By pressing both keys ZERO/SELECT "+/-" simultaneously for approx
5 seconds the alternating display mode is activated again.
HOLD - Key
Function - 1 - With the HOLD key a measured value may „frozen“. This value will be displayed
until by pressing the key SEND the LEVELMETER 2000 will return to the measuring
mode.
Function - 2 - When using the mode REL ZERO and ZERO the actual measuring value can be
accepted by pressing the HOLD key
