1. ADASH Ltd Adash 4400 VA4Pro Before Switching On Never connect higher then 30 V to the analyser 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 agains 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 If you are unsure contact your distributor or the manufacturer 4 For further technical and contact information visit www adash eu email info adash cz ADASH Ltd Adash 4400 VA4Pro General information The switch on Use the POWER button for switch on older versions had the button in different position as in the picture Connection to the computer Use the USB cable which is the standard accessory of VA4 set The small plug connect to the USB socket see the image above Connect second plug to the computer The instrument contains the standard Remove able disc with the VA4Pro_disc name That is why the usual windows for e g flash disc connection appear on the computer Close those windows When the operation failed switch off the unit and try to connect it again The charging The socket for external charger instrument accessory is under the POW2. 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 For further technical and contact information visit www adash eu email info adash cz ADASH Ltd Adash 4400 VA4Pro Sensors properties When you connect the sensors to the instrument you have to tell what kind of sensors you use The Sensors button is on most screens in the bottom A _ Update Global _ Push the Sensors button In the next menu select channel sensor you want define Ch2 Ch3 Ch4 All AC Channels DC1 DC DCS DC4 All DC Channels AC sensors AC sensors are used for alternate current signals e g vibrations After selection of Ch1 Ch4 or All AC Channels item the sensor properties menu appears e g Ch1 Type acc Sensitivity mV g 100 Unit g Angle 0 OK ICP on off selection of required setting accordingly the sensor type Type acc acceleration vel velocity disp displacement voltage force
