Figure 1.1 Overall view of ZET 7152-N-VER.3
ZET 7152-N-VER.3 is a complex multi-functional measuring complex, which includes:
1. ZET 7156 digital short-period seismometer
Digital short-period seismometer ZET 7156 is used for vibration velocity measurements of
high structures (bearing and enclosure structures) and underground structures (foundations, piles,
etc.). The seismograph consists of three identical sensing elements and a measuring module. The
sensing elements detect low-frequency mechanical oscillations by three mutually transverse axes
(X, Y and Z) and convert them into analog signal. The measuring module, in its turn, performs
digital processing of the analog signals and transfers digital data via CAN 2.0 interface.
2. Digital accelerometer ZET 7152-N
Digital accelerometer ZET 7152-N is used for measurements and conversion of acceleration
into a digital signal and further transfer of the data in digital format. The accelerometer consists of
a vibration sensor with integrated triaxial sensing element, which converts acceleration value into
a digital code by three mutually transverse axes X, Y and Z.
3. Off-line recorder ZET 7173
Off-line recorder ZET 7173 is used for recording the data obtained from digital sensors of
ZET 7152-N-VER.3. Data recording starts automatically as ZET 7152-N-VER.3 is switched on.
The data is saved to a microSD card as files in special format.
4. Synchronization module ZET 7175

LLC "ETMS"

Synchronization module ZET 7175 is used for synchronization of sensors time with global
time.
5. Interface converter ZET 7176
Interface converter ZET 7176 is used to connect the digital sensors of ZET 7152-N-VER.3
to PC via Ethernet interface as well as to configure digital sensors parameters.
6. Integrated battery
ZET 7152-N-VER.3 has an integrated battery allowing to record the registered signals to
non-volatile memory for further analysis by means of PC. ZET 7152-N-VER.3 data is transmitted
via Ethernet in real-time mode. Battery capacity enables measurements during 18 hours.

2.4 Connecting ZET 7152-N-VER.3 seismograph to PC
The PC should have Windows OS and ZETLAB software installed. It is also necessary to
connect ZETKEY (which is included into delivery scope) to USB port.
ZET 7152-N-VER.3 is connected to PC via Ethernet interface. In order to connect the
ZET 7152-N-VER.3 to PC via Ethernet interface, connect the cable PatchCord UTP (Cat. 5е) to
Ethernet port of ZET 7152-N-VER.3 and free Ethernet port of the PC. As ZET 7152-N-VER.3 is
connected to the PC, enable “Power” key at the top panel of ZET 7152-N-VER.3. The system will
find and install the corresponding driver.
IP address of the PC should be in the same network with IP address of interface converter
ZET 7176 (included into seismograph). Local network should not block UDP (multicast).
Note: By default, interface converter has IP-address 192.168.1.76 with mask 255.255.255.0.
Configuring of the devices included into the scope of ZET 7152-N-VER.3 is performed in
“Device manager” program from “Service” menu of ZETLAB panel. (Figure 2.1).
Figure 2.1 ZETLAB panel

The program “ZET Device manager” will search for available devices in the local network
and depict them in the list of devices (Figure 2.2).
Figure 2.2 “ZET Device manager”: list of devices
The devices in the list are shown in grey color, which means that they are available, but not
active. In order to connect to the interface converter, activate it from the menu with right click on
its serial number. (Figure. 2.3).
Figure. 2.3 Connecting to the interface converter
Note: Serial number of interface converter is specified in its product certificate.
During connection process, the device name will be highlighted with bold type. If the device
name is depicted in bold type for a long time, it means that it is impossible to establish connection,
Main reasons for that are as follows:
IP-address of the PC connected to ZET 7176 is not in the same network with IP-
address of the interface converter;

LLC "ETMS"
Tel./Fax.: [phone], www.zetlab.com
16
There is a conflict of IP-addresses: in the local network there is a device with IP-
address, identical with that of the interface converter.
In order to check current IP-address of the interface converter, enter the menu (with right
click on the interface converter), enter “Properties” menu and go to “Device” tab (Figure 2.4). The
parameter «IPv4 Address» will indicate the current IP-address of the interface converter.

As the connection is established, there will be formed a list of digital sensors connected to
the interface converter (Figure 2.5).
Figure 2.5 Active ZET 7176 and corresponding list of the sensors connected
The left section of the window depicts tree of devices, that are connected to the PC. The first
level depicts interface converters and devices, that are connected to PC. The second level shows
sensors, that are connected to a particular interface converter. To the right from the digital sensor
one can see device address in the measuring network (Figure 2.6).
Figure 2.6 Addresses of the devices in the measuring network
In the case if detailed display mode is enabled, the right section of the window will display
basic parameters of measuring channels.

Select the bit rate in accordance with the applicable requirements in the “Bit rate, kbps”
field of “CAN” tab (Figure 2.8).
Figure 2.8 «CAN» tab.
Note: After changing the bit rate of interface converter it is necessary to cycle power ZET
7152-N-VER.3. The system will automatically change the bit rate of digital sensors, which are
connected to the interface converter.

2.6 Configuring sensors included into the scope of ZET 7152-N-VER.3
Before starting to use ZET 7152-N-VER.3, it is necessary to configure corresponding digital
sensors.
Note: primary configuration of ZET 7152-N-VER.3 is performed by the manufacturer.
Please, note that in the field “Node 2 ÷ 63” of “Information” tab there should be set a unique
address of each device of the measuring network. All the devices within the scope of the
seismograph should have unique address –it is an obligatory condition for normal operation of
ZET 7152-N-VER.3. The nodes are set in the range from 3 to 63. Figure 2.9 shows an example of
“Information” tab of digital accelerometer ZET 7152-N with «3» node set.
