5. HOW TO INSTALL THE SOFTWARE
Re er to the quick user’s guide or so tware installation.
6. OPERATING INSTRUCTIONS
6-1. Activation of the Software and Setting of the Tablet PC (Nexus 7)

VM-2012 Air2 13/52
(5) Select the “Air-II-xxxxxx” listed in the networks as the access point.
(“xx” will be displayed arbitrary in hex notation).
(6) Once the status o the “Air-II-xxxxxx” is indicated as connected, the connection is success ully done.
At this point, the LED indicator is still red and blinking.
6-2. Measurement Method
Air2 can measure the vibration in 2 modes:
(1) OA Measurement
OA values o vibration data, such as acceleration, velocity, and displacement can be measured
and displayed. This mode is loaded with ISO and bearing criteria or quick diagnosis.
(2) FFT/WV
The wave orm data o the speci ied time can be gained. The wave orm and FFT data are
displayed. Since this unction accommodates continuous monitoring, real-time FFT analysis is
possible.
See the chapter 6-2-2 and a ter or more detailed description o each measurement mode.

6-2-1. Connection with the Air2
CardVibroAir2 icon will appear in the tablet PC display once the program is correctly installed.
Go to the CardVibroAir2 main menu by touching the icon.

WiFi Portable Vibrometer
VM-2012 Air2 15/52
Touch “Scan” in the lower right corner o the main menu. Turn on the Air2 and make sure the red LED
indicator is blinking.
Active Air2 device number(s)* will appear. Select the device and touch “Connect.”
The selected device number will be indicated as Sensor Type in the top o main menu page.
*The device number is the SSID number indicated in the label on your Air2 body.
You can con irm the connection by the WiFi icon on the upper right corner o the display or in the
measurement page.

6-2-2. OA Vibration Measurement
Once the tablet PC is success ully connected to the Air2, touch the “OA Vib. Measure” icon in main menu.
Touching the icon will lead you to the OA vibration measurement page.
Be sure the message, “Ready,” is indicated below the device number in the display. I not, go back to the
main menu and establish the connection.
When the measurement is completed, the values o acceleration (A), velocity (V), displacement (D), and
either E1, E2, or E3 will be shown.
You can also save the results as you speci y the in ormation o the measured spot. Re er to the chapter
6-2-4 or more details. In addition, quick diagnosis unction is available to evaluate the measurement
results based on the ISO standard.
6-2-3. Quick Diagnosis
You can go to the diagnosis menu by touching “Judge” button in the measurement result page.
You will see three evaluation criteria:
1. ISO Evaluation
2. Bearing Evaluation
3. User Evaluation
ISO evaluation is a judgment based on the ISO standard. On the other hand, bearing evaluation is a
judgment based on the envelope acceleration (E3).
And On User Evaluation, you can de ine the criteria level or each three unctions, namely Acceleration,
Velocity and Displacement. How to de ine is showed in User Judgment Edit page.
Select and touch evaluation method to see the judgment.

6-2-4. Data Save
The measurement results can be saved by using the database o the measurement spots.
Touch “Save” to go the data save page. Then, touch “Hierarchy.”
Select the Plant, Machine, and Point rom pull-down menu; then touch “Select” at the bottom o the page.
You may select these in ormation be ore measurement. In that case, touch the “Hierarchy” button in the
initial OA Vibration Measure screen to go to the data save page.
Touch “Save” to save the data.
You can move on to the next measurement, i needed.
The saved data can be converted into a chart, etc by using the optional data management so tware
(available at IMV).

And also you can type a short sentence at the Note window, and you can ind this note on the optional data
management so tware(DB-2012).
6-2-5. FFT/Wav Analysis
Touch the “FFT/Wav Analysis” icon in the main menu.
Be sure the message, “Ready,” is indicated below the device number in the display at this point. I not, go
back to the main menu and establish the connection.
As you touch “Start,” the Air2 starts the measurement.
Once the measurement is completed, you will see the wave orm or FFT data in the screen.
FFT and WV can be switched as you press the “FFT” or “WVE” button in the top o the screen.
Also, you can save the data just like the OA vibration measurement. Re er to the 6-2-4 to save the data.
By checking the checkbox o “Continuous” in the FFT/Wave analysis main menu be ore measurement, the
screen will display the wave orm or FFT data continuously. However, please note you cannot save these
continuous data.
