Before you begin read this manual
The VA4 unit is continuously developed and new functions and features are added often. Such additions also
require changes in manual and that changes can be very time expensive. That is why we do not change all
pictures in the manual so that are related to the latest version. Some pictures (which are usually only
backgrounds) remain in the manual although they were changed already. Certainly it is acceptable only on
places, where such background has no consequence.

Before Switching On
General warnings
Never connect higher then 30 V to the Analyzer !
Only suitable ICP powered sensors can be connected to the AC signal inputs.
If the measurement without ICP power is required, ICP power must be switched off. You can damage the
external signal source, which is not protected against ICP powering.
AC channels - voltage higher then
±
18 V (peak) can damage the instrument.
DC channels - voltage higher then
±
30 V (peak) can damage the instrument.
Always use only original cables designed for connection with sensor.
Long push and hold of POWER button evokes incorrect instrument switching off. Data could be lost.
If you are unsure, contact your distributor or the manufacturer.
PC USB connection warning
Switch off the A4400 instrument when you connect/disconnect it to/from computer by USB cable.
Ignoring any recommendations mentioned below may cause failure of the device.
Operating with a power higher then 24 V can cause an accident.
ADASH Ltd. Adash 4400 – VA4Pro

Battery charging
Charge the battery only at 0 - 40°C (30 - 100 °F) !
The unit uses Li-ION (LiON) batteries. This type of battery should not be discharged completely. If the battery is
discharged below certain Voltage, we call it deep discharging. The deep discharging shortens battery life. The
charging of deeply discharged battery takes much longer.
If the unit is not charged for longer period of time, then the deep discharge can occur. It is caused by self-
discharging of the battery. Another cause of deep discharge can be a situation when the unit is switched to the
SLEEP mode by the Power Off button (instead of switching off the unit).
When the battery is deeply discharged, it takes much longer to charge it again. Sometimes the indicator on the
charger does not light when the battery is deeply discharged – it does not mean it is not charging. Please keep
the battery charging even if the indicator does not light, the indicator will start light eventually.
To avoid deep discharge of the unit, charge the unit regularly, even when you don’t use it. We recommend you
to check if it is charged every 3 months.
WHAT TO DO WHEN YOU CANNOT SWITCH ON THE UNIT/ WHEN THE UNIT CANNOT BE CHARGED
NORMALLY:
-Discharged battery – battery needs to be charged (charging for approximately 3 hours), the unit can
be switched on normally with the charger connected
-Deeply discharged battery, when the unit wasn’t charged for longer period of time – the unit needs to
be charged completely until the indicator on the charger starts light green. It can take more than 12
hours. The indicator on the charged does not light from the beginning of charging process. Sometimes it
is not possible to switch on the unit even with the charger connected.
-Damaged charger – when the charger is connected, the indicator should start to light (green or orange
color), only with deep discharge the indicator does not light immediately.
-Sudden decrease of battery life – the unit needs to be charged and discharged completely few times
(usually 2-5 times). The battery lifetime should increase this way.

General information
The switch-on
Use the POWER button for switch-on (older versions had the button in different position as in the picture).
The green LED on the front panel ( right at the top) lights after switch-on.
The switch off
The switching off can be done by:
- Power Off button on the main screen,
- in the Global menu is the Power Off item available.
Auto switch off
If no button is pushed in 5 minutes from switching on, the unit will be switched off.
The emergency switch off
This is not correct method to switch off the instrument. Using it can cause data corruption. Use this method only
in case of emergency (eg. when the system freezes).
Push and hold the POWER button for about 5 seconds. Instrument will switch off.
Disc free capacity warning
If this warning message appears, you need to get free disc space by removing the measurements, routes or
records, which are not actual.

Connection to the computer
The instrument contains the flash memory (VA4_DISC), which is accessible from external computer.
Use the USB cable, which is the standard accessory of VA4 set. Connect the small plug to the USB socket (see
the image above). Connect second plug to the computer.
The charging
The socket for external charger (instrument accessory) is above the POWER button. The BAT LED on the
upper panel lights orange during charging. When the battery is fully charged, it lights green.
The DSP board - monitoring and reset
The DSP board is the most important part of the instrument. The special chip provides all necessary operations,
which are required for achieving of 4 channel synchronous data.
The STAT LED is on the top panel and enables to monitor the DSP board (older versions had the button in
different position as in the picture). Several states can appear:
- Green with 0.25sec time interval (4Hz, four times per sec) - the measurement is running.
- Green with 1 sec time interval - STANDBY, the measurement is not running.
- Red - the DSP board does not work properly.
When the red STAT occurs, do the reset of DSP board. Do not switch-off the instrument. Use the slim not sharp
thing (e.g. paper clip) and push the button, which is hidden in the RST hole.
Next LED is near each input connector:
- green – OK
- no light – no measurement is taken in this input
- red – error (usually ICP error).
Note: During the measurement are functional only LEDs for inputs used for measurement (e.g. red LED ends
the lighting during the measurement and starts again after it).
Virtual Analyzers Data Processing
When older Analyzers would take more measurements, they took them step by step. If the user wanted e.g.
acceleration overall, velocity overall, velocity time signal and velocity spectrum from one sensor, then the
Analyzers took first overall, then second overall with integration, then time signal and finally spectrum. The time
which was required for all 4 measurements was the sum of 4 individual times.
The instrument includes high speed chips and it uses the much more advanced concept. For every individual
measurement is created one virtual Analyzer in the instrument memory. All virtual Analyzers read data from
input DSP board and perform required data acquisition.
What does it mean? It means, that the total required time is not equal the sum of all individual times, but it is
equal the time required for the longest measurement.
Run the instrument on your computer
The A4410 Virtual Unit you can download from the producer’s website. Easily unzip the zip file and run the bat
file. Now you can easy try to work with all functions in your computer. Do not forget define the record as signal
source. You can also download the next records from that website. See the A4410 Virtual Unit chapter for more
details.

How to work with Menu
For the taking of measurements you have to define many parameters. All those definitions are providing by
menu items. The procedure for operation with all menu items is the same. We describe it on example - the
sensor properties definition.
Item selection
The sensor properties first menu appears after you push the Sensors button.
Use the arrow buttons for one item selection, e.g. AC2. Then push OK button. The second menu appears.
Again use the arrow button for one item selection. Then push the right arrow button to display possible
parameters of selected item. E.g. for Sensitivity you see this picture:
User defined values
Again use the arrow button for one sensitivity selection (1,10,100). In most of cases you want to enter the user
sensitivity according to the real sensor sensitivity of your sensor (e.g. 96,8 mV/g). Select the user and push OK.
The next window appears and the buttons get the numerical values entry functions.
ADASH Ltd. Adash 4400 – VA4Pro
13
Use the buttons and enter required value (e.g.45). If you need to edit the value, push the Shift button. The
buttons change the functions of buttons.
ADASH Ltd. Adash 4400 – VA4Pro
14
Now you can move the cursor, to use the Delete function. Press the Shift again and the buttons functions
change back. When the value is correct, push OK. The menu with new value appears.
Use the arrows and select the Save item. Press the OK button and the working with sensors menu will close.
Also you can use the Save button with the same function. When the Cancel button is used, then nothing is
saved.
As we mentioned the value entry, also the text has to be entered in some menu items. The screen looks similar
to the numerical screen. The only difference is the characters selection on buttons. It works like mobile phones
keypad, for second character selection you must press the button two times.
Multi-selection of items
Sometimes you could need to work with more then one item together. The usual example is the deleting of more
items in one step.
The left bottom button Multi on enables to select more items at once. Press the Multi on button. When you
move in the list by arrows, the items remain selected (red color) or unselected (black color). Press the same
button (now the Multi off) again for ending of multi-selection.
Example of multi-selected items. It needs a short time to play with and to find the right understanding of this
feature. The item with the cursor (the full blue field) can be selected or unselected too. The standard yellow
color means unselecting and the red color means selecting.
Searching of item
If the list is to long or you know the name, then use the Find button. Enter the name or part of name and
confirm.

Input channels
All input sockets are in the top panel. The versions older then 0200 had only 3 sockets in the panel.
The input sockets labeled IN1, IN2, IN3, IN4 are used for AC or DC signals. The input socket labeled TRIG is
used for trigger signals, usually tacho. All sockets have several pins. It enables to connect more signals to one
socket (see wire diagrams).
The AC inputs enable to measure max voltage peak +/-12V. The DC channels enable to measure max +/-24V.

Standard cable wiring
The standard cable, which are the part of the unit, have the sensor signal connected to the pin number 1. The
second sensor wire is connected to the ground (pin 2).
When you use this cable:
In IN1 socket, the signal will be measured on CH1.
In IN2 socket, the signal will be measured on CH2.
In IN3 socket, the signal will be measured on CH3.
In IN4 socket, the signal will be measured on CH4 (ver. 2.0 and higher).
If you want to use the 3-direction sensor, then you should use the IN2 socket ( pins 3,1,5) + ground (pin 2). You
need the special cable for this purpose.

A4409 - BNC Box
This box can simplify the connection of more cables to VA4Pro inputs. The BNC input connectors are used on
the top panel for connection of 4 AC channels and 4 DC channels. On the side panel are two Binder connectors,
which enable to connect all 4 AC channels to IN2 input and all 4 DC channels to IN3 input.
See the wiring diagram of IN2 and IN3 in previous chapter. You see, that all 4 AC channels can be connected to
one input IN2. In the same way all 4 DC channels can be connected to one input IN3.
