2. Outline
2-1. SmartVibro
SmartVibro is an acceleration meter placing emphasis on analysis, which is equipped with functions of
H-function measurement, i.e., envelope processing. This machine serves various uses in measurement
including checking the machines and equipment from various points of view. With SmartVibro, you can not
only analyze the bearing, but also measure the acceleration amount and check fluctuation components in
low-speed rotating machinery bearings.
2-2 Features
■Analysis Capability
RMS value of acceleration and H-function measurement enables precise data gathering that benefits
your decision-making process.
■Simultaneous Measurement
High-speed processing CPU enabled simultaneous display of acceleration, velocity and displacement of
velocity signal coming from the sensor.
■LCD Screen
Various settings like measurement conditions are possible by a touch panel.
■FFT Analysis Function (VM-4424H Only)
Real-time FFT analysis is possible with a minimum condition setting to check vibration frequency
components.
■Waveform Data Save (VM-4424H Only)
Waveform can be stored.
Stored data in the SD card can be exported to a personal computer.
■Language
SmartVibro can be operated in Japanese or English by changing the setting.
■Volume Control
Volume is controllable with the digital volume.

3.1 Before Getting Started
(1) You can select the computing method for velocity, acceleration, and displacement. Refer to the
Chapter 4-2 for more details. Initial settings are as follows:
■Acceleration : rms
■Velocity : rms
■Displacement : EQP (Equivalent Peak)
(2) Check the polarity carefully, and set two (2) AA batteries in the battery box. (NiCd or Alkaline)
For the use with the AC adaptor, connect the AC adapter cable to the power connector in the
bottom of the device.
(3) Connect the pickup cable to the pickup connector.
Refer to the following chapters for measurement.
The pickup needs to touch the subject for measurement.
★For the method to fix the pickup, refer to the page 25.
(4) Language Setting
You can select Japanese or English to be displayed on the screen. Refer to the Chapter 4-9 for
details.

You can operate the device by using the touch screen and two function buttons.
Japanese English
Fig 2 Initial Screen
(1) Standard Measurement Mode
VM-4424S is equipped with this mode only.
(2) Measurement Range Bar
This shows the level of measurement data. The data is not absolute, but rough indication.
(3) Function Indicator
Valid functions are indicated. In the Fig 2, “Start” and “Setting” are operative.
(4) Battery Indicator
This appears when the battery level is low.
(5) Function Button (L)
In the measurement mode, you can start or hold measurement when you press this button. In the
setting mode, you can check the battery level. (Chapter 4)
(6) Function Button (R)
In the measurement mode, range display will appear when you press this button. In the FFT mode
(available only with the VM-4424H), this button would switch the display from detailed to simple
indication of the result, and vice versa. (Chapter 5) As for the range setting, refer to the Chapter 4.
