INTRODUCTION
The V9000 Seismograph is an intelligent data logging Seismograph that
can be configured to perform various monitoring operations. It is a
lightweight, battery powered weather-proofed unit that is designed for use
in rugged conditions, from demolition / construction sites, to quarries and
underground locations. The V9000 Seismograph is also ideal for
monitoring in Commercial and Industrial locations as well as Residential
properties.
The V9000 Seismograph can store vibration data for all 3 axes at 1
millisecond intervals, and show frequency plots for the dominant
frequencies of each axis.
There are many options available for the V9000 Seismograph, such as the
air overpressure microphone, 2 stage audible / visual alarm, VDV (Vibration
Dose Value) monitoring, a twin channel upgrade, GPS module, the ability
to upload data remotely via the internet, and various text alarm functions.
The V9000 Seismograph can also be powered from an external power
source such as 240 v mains adaptor or a 12 v battery.
The basic operation of the V9000 Seismograph is the same, no matter
which options are fitted to the unit. For a full description of each function
please refer to the relevant section depending on the configuration and
options fitted to your V9000 Seismograph.

Seismographs can be extended by a further 10 years at
no additional cost (to the standard calibration cost)
providing the V9000 Seismograph is calibrated by Vibrock
Ltd every 12 months.

INST/MAN/V9000/06/23.02.21 Page 3
BASIC OPERATION
The V9000 Seismograph is powered by four ‘D’ Cell batteries, and has a 20
line x 40 character LCD together with 4 push-button switches. The display
has a backlight, so can be used where light conditions are poor. The push-
button switches correspond to the instructions shown on the LCD display.
Users will be familiar with this method of operation as it is the same as a
Bank a.t.m. machine (cash machine).
To switch on the Seismograph, press the Silver push-button.
The display will power up, showing Vibrocks’ contact details (and the MAIN
MENU option), and the Red light set in the Silver push-button will flash.
This Red light is to show there is sufficient power in the batteries.
Press the push-button for the MAIN MENU option and the unit will now go
into its start up page, with the top line showing date, time, battery voltage,
serial number, USB connection and modem status. The display will also
show:-
VIEW PILING BLASTING
SHIFT MEMORY MODE MODE
SHIFT - Pressing (and holding) this option allows the user
to select other options such as custom set up.
VIEW MEMORY - This option allows the user to view or delete ALL
the contents of the Seismograph’s memory.
PILING MODE - This option puts the Seismograph in the
continuous mode of operation where all vibration
levels are logged at 5 second intervals.
BLASTING MODE - This option puts the Seismograph in the trigger
mode of operation, where data is stored at 1
millisecond intervals for each axis. The default
trigger level is 0.5 mm/s.

INST/MAN/V9000/06/23.02.21 Page 4
SHIFT FUNCTION
When the user presses and holds down the SHIFT push-button, the display
will show a new set of options such as the examples shown below:
VIBROCK CONTACT - This option shows Vibrock Limited contact details.
CUSTOM MODE - This option allows the user to set the date and time
of the Seismograph and to set up the Seismograph
using its custom mode settings.
MAIN MENU - This option takes the user back to the main menu
screen.
Other options are shown when the user is setting up the Seismograph for
monitoring, etc.
STANDBY / SLEEP MODE
The V9000 Seismograph has a standby and sleep mode, which allows the
four ‘D’ cell batteries to last for 4-5 weeks.
The standby mode is when the unit is on but not monitoring, it will power
down after two and a half minutes if no push-buttons are pressed. This is
to save battery power. Pressing any button will power the Seismograph
back up to its on state.
When the unit is on and monitoring, the display backlight will turn off after
twenty five seconds, and the display will turn off after another two and a
half minutes, but the RED light on the Silver push-button will give a double
flash to indicate it is still monitoring. This is the sleep mode. Pressing
any push-button will wake up the unit and the monitoring screen will be
displayed.
NOTE: When the Seismograph is connected to a PC, the internal batteries
are switched off and the Seismograph is then powered by the USB socket.
Sleep mode is disabled whilst the Seismograph is connected to the PC.

TRANSDUCER MOUNTING
One of the most critical aspects of vibration monitoring is the placement
and coupling of the measurement transducer. The accuracy of any seismic
reading is only as good as the quality of the connection between the
transducer and the ground surface.
This connection, known as coupling, is vitally important in obtaining valid
results. While it may seem that placing a sensor on firm ground, and even
spiking it into the ground, should provide good coupling, often it does not.
In order to be sure that the seismograph is faithfully recording the actual
motion of the ground, the link between the ground and the sensor must be
no less than perfect.
The potential for decoupling becomes greater with high particle velocities,
associated with high-frequency vibration, i.e. high accelerations. Thus, the
problem of decoupling is most often seen when recordings are made at
short distances. This is when the highest frequencies are present, as well
as the highest particle velocities.
At acceleration levels greater than 0.2g the transducer should be buried
completely when the measurement surface consists of soil. When done in
a careful manner, this is probably the ultimate way of assuring that perfect
coupling with the ground is obtained. However, if not done properly, this
method can also lead to erroneous readings.
A sandbag can also be effective if used properly, being loosely packed and
large enough so that, when placed on the sensor, all sides of the bag are
resting firmly on the ground surface. When measuring on a firm surface,
attachment can also be by means of resin or bolting. When recording
within a building, bolting or high modulus resin should be used on vertical
surfaces.
Measurements on floors having compliant coverings should be avoided.
British Standard guide 7385: 1990 discusses the mounting of transducers
located within buildings in greater detail. The same document discusses
monitoring being undertaken at different levels within a building to identify
dissipation or magnification as well as simultaneous monitoring on the
building foundation and ground outside to establish transfer functions.

PILING (CONTINUOUS) MODE
In normal operations with one PPV (red) transducer pack, default settings
are pre programmed for this mode of monitoring.
The Transducer must be placed firmly in the measuring location and
levelled by the use of the adjusting legs. Always tighten the locknuts to
avoid any possibility of movement and hence erroneous readings. At
particle velocity levels above 5 mm/s the use of fixing methods is
recommended. Methods of fixing are gluing the levelling feet with rapid
epoxy, bolting a clamp over the transducer or placing a sandbag over the
transducer. Shallow burial can be used if no other method is possible. It is
important to ensure that the transducer is firmly fixed down. If this is not
done correctly, the transducer may bounce slightly during a transient
vibration. This will always give a HIGH reading.
The default settings for PILING MODE are:-
Transducer A
PPV Peak
Continuous mode
5 second data storage interval
0 - 200 mms-1 auto scale
No timer, text or alarm function
When Piling mode is selected, the Seismograph carries out an internal set-
up procedure and then displays the scanning screen. The Red light in the
Silver push-button will double flash. This double flash is to show the unit is
in monitoring mode.
The Seismograph will display data for all 3 axes at the pre-set scanning
interval (5 seconds). Data is also stored at this interval. The operator can
view the bar graph of the data by pressing BAR GRAPH.
To stop the monitoring session, press and hold the SHIFT push-button and
press the EXIT push-button. This procedure will take the operator back to
the main menu screen.

INST/MAN/V9000/06/23.02.21 Page 7
BLASTING (TRIGGER) MODE
In normal operations with one PPV (red) transducer pack, default settings
are pre programmed for this mode of monitoring.
The Transducer must be placed firmly in the measuring location and
levelled by the use of the adjusting legs. Always tighten the locknuts to
avoid any possibility of movement and hence erroneous readings. At
particle velocity levels above 5 mm/s the use of fixing methods is
recommended. Methods of fixing are gluing the levelling feet with rapid
epoxy, bolting a clamp over the transducer or placing a sandbag over the
transducer. Shallow burial can be used if no other method is possible. It is
important to ensure that the transducer is firmly fixed down. If this is not
done correctly, the transducer may bounce slightly during a transient
vibration. This will always give a HIGH reading.
The default settings for BLASTING MODE are:-
Transducer A
PPV
Trigger mode
0.5 mmS-1 trigger level
No timer, text or alarm function
When Blasting mode is selected, the Seismograph displays the scanning
screen and the Red light in the Silver push-button will double flash. This
double flash is to show the unit is in monitoring mode.
When the Seismograph detects a ground vibration at or above the preset
trigger level, the unit will trigger and the maximum vibration levels will be
displayed. The Seismograph will still carry on scanning for ground
vibrations until the operator stops the monitoring session.
To stop the monitoring session, press and hold the SHIFT push-button and
press the EXIT push-button. This procedure will take the operator back to
the main menu screen.

CUSTOM MODE
When custom mode is selected, the user can set the time and date of the
Seismograph as well as select custom settings such as changing the
trigger level, scan / storage interval, timer function, alarm function, entering
a location name, and setting the modem text alarms (if the modem option is
fitted).
CUSTOM MODE - SET CLOCK
Selecting the SET CLOCK option, allows the user to set the date, time and
day, by using the UP, DOWN and SELECT functions.
Once the correct information has been input, press the SHIFT and
UPDATE CLOCK option, and the date, time and day are set.
CUSTOM MODE - SET LOGGER
Selecting the SET LOGGER option, allows the user to select different
modes and units for vibration monitoring. The user can also select different
trigger levels and scan intervals, alarm trigger levels and the option to input
an SMS message which is transmitted when an alarm level is exceeded
(modem option required).
The V9000 Seismograph also has a timer function which allows the user to
set the monitoring times for each day of the week (this eliminates the
storage of unnecessary data). This function also extends battery life.
When the SELECT LOGGER option is selected, the user follows the on
screen instructions to choose their settings. Once all settings have been
input, the user presses and holds the SHIFT push-button and selects
START LOGGER. The Seismograph now enters the custom monitoring
mode.

INST/MAN/V9000/06/23.02.21 Page 9
CUSTOM MODE - SET MODEM (OPTION)
This option is visible if the modem is fitted, and allows the user to turn the
modem on or off, view signal strength, connection status and modem
battery charge level.
When the V9000 Seismograph is switched ON, the modem is also ON, and
will remain ON, until the operator switches it OFF in the custom set up, or
switches it OFF, when the V9000 Seismograph is switched OFF.
To turn OFF the modem, at the main menu screen, press SHIFT and SET
LOGGER, MODEM. Select MODEM DISABLE. The screen will now show
‘waiting for modem OFF’, then after a few seconds the screen will show
‘modem OFF’. Press EXIT and the main menu screen now appears.
The operator can now select the mode of monitoring required.
BATTERY POWER – IMPORTANT INFORMATION
If the V9000 Seismograph has the modem fitted, then please read the
following:
When the V9000 Seismograph is switched ON, the modem is also ON, and
will remain ON, until the operator switches it OFF as described above.
The modem is powered by a separate internal re-chargeable battery. When
the modem battery goes flat, the modem switches off, but the Seismograph
will carry on monitoring.
The V9000 Seismograph can be set to send a text message (see page 20
– status tab), warning the operator that the modem and / or the ‘D’ cell
batteries are about to run flat, and therefore require charging / replacing.
The modem battery can be re-charged using the supplied 12 volt battery
charger.
