5.2. Note at initial startup
b
After starting the device for the first time, the message “SET TIME”
appears on the display. However, no settings need to be made directly
on the device. The time synchronises itself with the PC time automatically when
connected to the SmartGraph software for the first time.
6. Operation
The PC software SmartGraph is the central configuration interface for your data
log
ger. All additional configuration and visualisation specifications can only be
set by software.
Basic settings can be directly configured with one-button operation by using
the mode selection button on your data logger.
You can restrict the one-button operation with the mode selection button from
your software if necessary (key lock). It is not possible to operate your data
logger with the mode selection button in this case.
6.1. S
witching on and off
When current is being supplied, the data logger cannot completely switch off,
but can only be set to an operating mode with minimal energy consumption
(M1). In this mode, measured value detection, measured value display and data
recording are inactive. An overview of the four various operating modes is pro-
vided in the next chapter.
6.2. B
asic settings and operating modes
Eleven basic settings can be configured by using the mode
selection button. These include the four various operating
modes, the network function, a global reset of settings, the
acoustic function and various settings for configuring external
sensors.
Briefly pressing the mode selection button changes to the
current setting level.
Briefly pressing the mode selection button allows navigation
through the individual setting modes.
Each chosen mode is shown for four seconds and
can be selected.
Within this time, the mode marker flashes in the bottom left
corner of the display (M1, M2, M3, M4, M51, M52, M53, M6x,
M7x, M81 (An0), M81 (An1)).
Pressing the mode selection button for 1 second confirms
your selection.
The data logger then changes to the selected mode.
If no selection is confirmed within the four second period, the
setting level is left and the display returns back to the original
mode without making changes.
* This function is only available if a BUS sensor has already
been registered (M61).

5. Preparation before starting
5.1. Software
5.1.1. Installation conditions
To configure your data logger and read the recorded measured values, the
SmartGraph software must be installed on a PC with the following minimum
requirements.
Supported operating systems:
• Windows XP from Service Pack 3 (32 bit or 64 bit version)
•
Windows Vista (32 bit or 64 bit version)
• Windows 7 (32 bit or 64 bit version)
Hardware requirements:
• Processor speed: 1 GHz, min
imum
•
CD-ROM drive
• USB or network connection RJ45
• 512 MB RAM, minimum
• 4 GB of free hard disk space, minimum
• Adobe Acrobat Reader software
5.1.2. Installation of the SmartGraph software
Insert the CD-ROM into your PC drive and install the software by following the
instructions in the installation wizard.
5.1.3 Preparing data logger configuration
If necessary, connect the external sensors which are needed for detecting
measured values to the external connections of your data logger.
Information about connecting and configuring suitable sensors is provided
in chapters 7 and 11. Follow the instructions in chapter 7 for connecting ex-
ternal sensors and then continue with startup.
Afterwards, connect the data logger to your PC via the USB cable provided in
the scope of supply. The measuring device is automatically detected by the
SmartGraph software.
Alternatively, you can configure your data logger via a LAN connection over
your local network if the network function is enabled. Further information about
the network function is provided in chapter 6.2.2.
Start the SmartGraph software. The program automatically detects the connected
data logger and adds it to the list of available data loggers. The data logger can
now be configured via the software.
Further detailed information about using the software is provided in the
software manual which you can open from the help function of the Smart-
Graph software.
.2.1. The four operating modes
6
Operating mode M1
Selection of the operating mode M1 Display of the operating mode M1
Measured value recording is inactive. “OFF” is shown in the second measured
value row. The STOP symbol is shown.
In this operating mode (data logger delivery state), the power consumption is
minimal because measured values cannot be requested or shown.
Measured values are not shown in any of the three measured value rows. Still,
in this operating mode, up to twenty measuring channels, which can be selected
in the SmartGraph software, are stored in the measured value memory. The
display for measured value recording thus shows REC (data recording).
6.2.2. Network function (M51)
Requirements for connecting over a IPv4 network.
To automatically identify the IP configuration of a data logger (which has received
an IP address in the IP network via DHCP for example), it is necessary that UDP
broadcasts are allowed through the network.
Note: Based on their concept, UDP broadcasts do not operate

the data logger is outside of the network, using fixed IP addresses through a
system administrator is highly recommended.
through a router (NAT), but instead only within its own network. If
Operating mode M2
Selection of the operating mode M2 Example display of the operating mode M2
Measured value detection is active. The measured values which have been con-
figured in the SmartGraph software are shown in all three measured value rows
at the selected sensing rate.
In this operating mode, data recording is inactive; the displayed measured
values are not saved in the memory. The display for measured value recording
thus shows STOP (no data recording).
Operating mode M3
Selection of the operating mode M3 Example display of the operating mode M3
Connect to the network
Selection of the network function M51
If the data logger is connected to a local network and the network function is ac-
tivated, then software configuration and data reading from the data logger can
be carried out over the network.
A signal which is broadcast from the data logger over UDP allows the SmartGraph
software to automatically find the measuring device in the local network.
The first time that the data logger is connected to the network (add network
device), it may be necessary to adjust the data logger's network settings to the
configuration of the available network in the SmartGraph software. The factory
preset is DHCP.
Further information about the network function is provided in the
software manual which you can open from the help function
of the SmartGraph software.
With the professional version of the SmartGraph software, it is also possible to
retrieve and log current and saved measured values of the data logger in ad-
justable request intervals over the network.
Example display of the network function M51
Measured value detection and data recording are active. The measured values
which have been configured in the SmartGraph software are shown in all three
measured value rows at the selected sensing rate.
Additionally, in this operating mode, up to twenty measuring channels, which can
be selected in the SmartGraph software, are stored in the measured value memory.
The display for measured value recording thus shows REC (data recording).
Operating mode M4

Use in network mode
For continuous use of the network card, the data logger must be mounted on
a wall. There must be a free air convection within a gap of a half metre and the
zone must not be interrupted by external sources of convection (fans, lighting
etc.).
Power supply in network mode
Using the network card, which is built into the data logger, raises the power con-
sumption of the measuring device.
When the device is running on batteries alone and not connected to an external
power supply, it automatically deactivates the network function after 12 minutes
pass without communicating with the network. In this case, the network function
must be restarted by an external power supply either manually or automatically.
When using the data logger in LAN mode, the power should thus
