1.3 Hints for the use of sensors and cables
Sensors and cables can be damaged
• Protect the sensors from the exceeding of the allowed power supply range,
mechanical overload and wrong pin assignment.
• When using sensors without ISDS (Intelligent Sensor Detection System), you have
to enter the sensor parameters error-free into the instrument.
• The measuring cables MK01 and MKS may not be lengthened, otherwise the
shielding will be interrupted.
• The data of an ISDS sensor will be read into the instrument after it is switched on.
When you connect new sensors, the instrument must be switched off and on to
write the sensor data into the device memory.
1.4 Hints for the connection of printers
Not all printers are supported
The measuring instrument supports printers with centronics interface, only. Due to the
large variety it is not possible to support all printers in the market. This is why
Hydrotechnik only assures the complete support of those printers contained in the
printer selection list of the instrument. Please contact our customer support for
questions, whether your printer is supported.
1.5 Hints for the use of the touchpanel
Treat the touchpanel carefully
The measuring instrument is equipped with a touch-sensitive monitor. By touching
certain parts of the display, you can give commands of activate settings.
• Touch the monitor gently! Let your finger rest a moment on the surface to trigger
the desired function.
• Never knock on the monitor with impetus or force. This will damage the surface!
• Keep the monitor clean. Never use aggressive or strong detergents or solvents.
Normally, a slightly dampened soft cloth is sufficient for the cleaning, persistant

3 Description of the measuring instrument
3.1 Qualities of the MultiSystem 8050
The MultiSystem 8050 is a practice oriented, user-friendly measuring system that supports the user in his daily
measuring tasks efficiently. When using ISDS sensors, the MultiSystem automatically detects the connected
sensors during the start-up and reads in all parameters: measuring range, physical measurand, units, output
signal and characteristic curve (linearisation). A mix up of the sensor and the manual entry of the sensor data
are things of the past. But you are always free to connect sensors withóut ISDS signal to the instrument. Then
you can use clearly arranged operation menus for the input of the parameters.
The saved measuring data can be transferred fast and easy to a PC by using the USB interface. The evaluation
software HYDROcom is delivered free of charge with the instrument and allows the comprehensive, detailed
and professional evaluation and presentation of the measuring data.
You may connect up to 32 (40 at the special version “40 channels”) sensors and save all measured values.
Various calculations with pre-defined or freely programmable formulas can be assigned to special channels that
can be displayed and/or saved. The minimal and maximal values of all channels are stored permanently and
can be displayed at any time.

4 Operation of the measuring instrument
Differing screenshots
In this manual screenshots are shown that were taken with a special software.
Sometimes they look slightly different than what is displayed at the MultiSystem 8050,
but the contents are always identic.
The operation of the measuring instrument is almost completely done with operation menus displayed on the
touch-sensitive monitor. Only the switching on and off is done using the switch at the left side of the device.
4.1 Switch instrument on and off
Connect ISDS sensors first
If you use sensors with Hydrotechnik ISDS (Intelligent Sensor Detection System), you
will have to connect them to the instrument before you switch it on. During the launch
sequence the sensor data will be read and applied to the channel settings. If you
connect ISDS sensors to a running instrument, you will have to switch it off and on to
let the device read the sensor data.
The following preconditions must be fulfilled, before you switch the instrument on:
• an original power pack must be connected to the instrument and the supply voltage
• all desired ISDS sensors must be connected to the instrument
Now press the main switch (see position 8 in Pic. 2 on page 9) and switch it into position “I”. The instrument
starts a self-test and this screen will be displayed (among others):

Here you may display up to 30 measured and/or calculated values at the same time. The number is selected in
the display menu. Up to five information elements are shown for each channel:
1 channel name
2 channel number
3 minimal value (in MinMax mode, only)
4 current value
5 maximal value (in MinMax mode, only)
6 measurand with index and units
The function bar contains two (in measured value mode) or three (in MinMax mode) buttons:
Meas.val./MinMax toggles between the modes; in MinMax mode, the minimal and maximal values since the
last deletion are displayed together with the current measured value
Delete (in MinMax mode, only) deletes the minimal and maximal values
Hold displays the last measured value („freezes“ the display)
More buttons
In the memory mode the function bar contains more and different buttons. These will
be explained in chapter 6 starting on page 42.

Pic. 9 Display mode „GRAPHIC“
Here you may display up to 30 measured and/or calculated values at the same time. The number is selected in
the display menu. Three information elements are shown:
1 current position (current measured values)
2 curves of the measured values
3 numerical display of the current measured values or of the graphic scaling
The function bar contains three buttons:
Meas.val./MinMax toggles the display modes
Values/Scaling toggles between the numerical measured value display and the graphic scaling
Hold displays the last measured value („freezes“ the display)
Hint
When displaying MinMax values graphically you will mostly get a broad band of
curves. These are the minimal and maximal values that appeared within the set
display rate.

5.1 Channel menu
Pic. 12 Channel menu
All channels of the MultiSystem 8050 are displayed in this overview. Eight different types of channels can be
distinguished:
Analog inputs ch1 ... ch10; inputs for analog sensors, connected to the analog input jacks
at the rear side of the instrument (see pos. 23 and 24 in Pic. 4 on page 9)
Inputs for current/voltage ch11 and ch12; inputs for sensors connected to the input jacks at the rear
side of the instrument (see pos. 20 and 21 in Pic. 4 on page 9)
Frequency inputs ch13 ... ch16; inputs for sensors connected to the frequency input jacks at
the rear side of the instrument (see pos. 22 in Pic. 4 on page 9)
Trigger input/output ch17 and ch21; input or output for external trigger; connected to the jack at
the right side of the instrument (see pos. 18 in Pic. 3 on page 9)
Digital inputs ch18 ... ch20; inputs for digital signals, connected to the terminal at the right
side of the instrument (see pos. 17 in Pic. 3 on page 9)

5.1.1 Configuration of analog inputs (ch1 ... ch10)
No programming required for ISDS sensors
The analog input channels must only be configured, if sensors without ISDS are
used. ISDS sensors must be connected to the instrument before it is switched on.
Then the sensor data will be read during the start-up sequence.
Pic. 13 Configure analog inputs
Variable touch the yellow box to open a screen with the available measurands; touch the desired
measurand (observe units!) and then [OK]
Name touch the entry box and use the virtual keyboard to enter the desired channel name
Index variable this will be assigned to the selected measurand automatically; all channels with identic
measurand will be numbered consecutively
Possible disadvantages of automatic indexing
The automatic indexing may influence the settings of different channels. If e.g. channels 1 and 4 are set to
“p”, channel 1 is “p1” and channel 4 is “p2”. If you now set channel 2 to “p”, the numbering will be updated:
ch1 = p1, ch2 = p2, ch4 = p3. If you do not want this, you may switch off the automatic indexing in the
device menu and assign the index numbers individually.
Sensor type select the output signal of the sensor connected to the channel
Measuring range touch the two entry boxes and enter the measuring range of the sensor
Zero point the value of the last zero point alignment is displayed here (see below “Execute zero point

3. The new value will be displayed after the alignment has been completed.
Use linearisation tables
The measuring accuracy of a sensor can be increased by using a linearisation table. The correction values
determined during a sensor calibration will be taken into a table. These correction values should be contained in
the calibration protocol of the sensor. You may enter max. five linearisation tables per channel.
1. Touch the button [Use linearisation]. The linearisation function is active as long as the button is green:
Pic. 15 Linearisation function
The buttons for the selection of the linearisation table 1 to 5 are yeloow now and can be selected. The
values of the selected table are displayed in the rectangle. Table 1 is selected in the shown example.
2. Touch the button of the linearisation table that you want to use. If you want to create a new table, you
should touch an “empty” button (here buttons 2 to 5).
3. Touch the button [Edit lin. table]:
