Calls attention to a procedure, practice, or condition that could possibly
cause bodily injury or damage to instrument.
Represent handling precautions or notes on product specifications.
Indicates product specification information and actual usage information.
●For safe use
In case of the place of objective instrument is high temperature, near rotating
shaft and near a moving element, the mounting of pick-up, please go to when
the machine is stopped.
In such a place, measuring the vibration with pick-up in one’s hand, it causes
burn injury and cable engulfment. It is very dangerous, please stop

2. Outline
2-1. SmartVibro Overview
SmartVibro is a portable digital vibrometer designed to measure the displacement,
velocity, and acceleration of vibration of various machineries such as machine tools,
rolling mills, forge rolling machines, pumps, air blowers, compressors, electric motors, and
turbines. Ideal for JIS standard inspection, quality control, and maintenance inspection.
In addition, vibration severity can be measured in accordance with “Instrument for
measuring vibration of rotating machines and reciprocating machines (ISO2954 *)” defined
by ISO (International Organization for Standardization).
* ISO2954 is available from ISO website.
(https://www.iso.org/home.html)
2-2. Features
■Frequency Range
10Hz to 1kHz
■Simultaneous Measurement
High-speed processing CPU enabled simultaneous display of acceleration, velocity and
displacement of velocity signal coming from the pickup.
■LCD Screen
Various settings like measurement conditions are possible by a touch panel.
■Electrodynamic Velocity Pickup
The electrodynamic velocity pickup complies with the ISO2954.
High-sensitive measurement is possible.
■FFT Analysis Function (Only VM-3024H)
Real-time FFT analysis is possible with a minimum condition setting to check vibration
frequency components.
■Waveform Data Save (Only VM-3024H)
Waveform can be stored.
Stored data in the SD card can be exported to a personal computer.
■Language
VM-3024 can be switched freely between Japanese and English.

3-1. Before Getting Started
(1) You can select the computing method for velocity, acceleration, and displacement.
Refer to section 4-2 for more details. Initial settings are as follows:
■Acceleration (ACC): rms
■Velocity: rms
■Displacement: EQP
(1) If you are familiar with our VM-3004 or VM-
3304, EQP setting for the
displacement is highly recommended. Since the measurement data with the VM-
3004 and VM-3304 is indicated in EQP, you may easily compare the data with the
same setting.
(2) For measurement of the vibration severity, velocity setting needs to be “rms.”
(2) Check the polarity carefully, and set two AA batteries in the battery box (Ni-Cd or
Alkaline) (Fig.3-2).
For the use with the AC adaptor, connect the AC adapter cable to the power connector
in the bottom of the device.
(a) Installing AA batteries (b) Attaching the AC adapter
Fig.3-2 Power Supply Method
Pay attention to the polarity of the battery.
(3) Connect the pickup cable to the pickup connector.
In addition, when measuring, pickup installed or fixed for object. For actual measurement,
refer to the following sections.
Refer to section 10 when fixing the pickup.
(4) Display Language Setting
VM-3024 can switch between Japanese and English as needed. Refer to section 4-6.

3-3. Operations during Measurement
Touching “Start” on the touch screen or press “Measurement Button” in Fig.3-3 would
start measurement. The screen displays measurement status (Fig.3-4).
Once you touch “Hold” on the touch screen or press “Function Button” would hold
measurement and the display (AC output when stopped is not retained).

(1) How to change the Range
When the Auto Range function is “OFF” (refer to section 4-4.), the range key will
be activated during measurement (Fig 3-4).
Touching “Range” on the touch screen or pressing “Function Button” will show the
range setting display. You may adjust the range accordingly.
The icon will appear on the upper right corner of the screen when the value is
over the range (Fig.3-5).
(2) About Excessive Input State (Measurement Impossible State)
When is displayed on the upper right of the screen, regardless of main unit
version, input speed value exceeds the hardware range (amplifier gain), and the
waveform is distorted and unsuitableness state.
In this case, do not use it as a measurement value because it is not possible to
measure accurately.

(1) A brief Description of each Calculation Method
rms: “rms” is “Root Mean Square”. This is the square root of the mean of the squares
of the time-series data gathered from measurement. ISO standard sets RMS as
evaluation criteria of the vibration velocity, which is also known as vibration
severity.
EQP: EQP is a value gained by “rms”× √2
. This formula is suitable to use for
measurement of sine vibration generated by rotational machines, for example.
Peak: The maximum value of the time-series data.
For detailed explanation, refer to the definitions in Section 10.
(2) Setting of VM-3004 and VM-3304
When had used VM-3004 and VM-3304 in past, should not use “Peak” setting, but use
the same setting as VM-3004 or VM-3304.
Recommended settings for VM-3024 are as shown in the table below.
