1. Introduction

We truly appreciate your purchase.
Please read this manual carefully before use and follow the cautions below for your safety.

Should you have any inquiries or find a problem during use, please consult our sales office near you or IMV
quality assurance department.

1. If the subject of the measurement could be hot, rotating, or near the movable
parts, assure the safety and fix the pickup for measurement.
Do NOT hold the pickup manually in these cases to avoid any possible accidents;
including burning yourself, and entangled cables.

2. Follow the instructions printed on the battery for replacement and disposal of used
batteries. Pay attention to the polarity of the battery for installation.

2. Outline

2-1. SmartVibro

SmartVibro is a portable vibration meter with high-sensitivity and accuracy to measure micro vibration
of super low frequency. Its application varies widely; measuring and analyzing vibrations, evaluation
and maintenance of the ground and/or floor of various architectural constructions, precision machines
in the laser and semiconductor industries, and low-speed machineries in energy harvesting and
hydroelectric generation.

2-2 Features

■Frequency Range

0.3 – 100Hz; Sensitivity: Full scale 0.1m/s2 (Equivalent to 0.01G, 10Gal)

■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.

■Acceleration Pickup

Square pickup can be attached to the subject of measurement in any orientation.

Durable acceleration: 300m/s2 (30G)

■FFT Analysis Function

Real-time FFT analysis is possible with a minimum condition setting to check vibration frequency

components.

■Waveform Data Save

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.

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)

★ If you are familiar with our VM-7000L, EQP setting for the displacement is highly recommended.

Since the measurement data with the VM-7000L is indicated in EQP, you may easily compare the
data with the same setting.

★ For measurement of the vibration severity, velocity setting needs to be “rms.”

(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 30.

(4) Language Setting

You can select Japanese or English to be displayed on the screen. Refer to the Chapter 4-9 for
details.

3-2. Measurement Screen

Turn on the SmartVibro by sliding an orange switch on the left side of the device. Initial screen
(Fig 2) will appear.
You can operate the device by using the touch screen and two function buttons.

Japanese English

Fig 2 Initial Screen

(1) Standard Measurement Mode

You can measure the OA value of acceleration in this mode.

(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) 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)

(5) 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-3024H), 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.

(6) Battery Indicator

This appears when the battery level is low.

(7) FFT

FFT mode starts when this tab is activated. (Chapter 5-1)

(8) Data Save

Data save mode starts when this tab is activated. Waveform will be stored in the SD card as plain
text. (Chapter 5-2)

3-3. Operations during Measurement

Touching “Start” on the touch screen or press the function button L in the Figure 2 would start
measurement. The screen displays measurement status. (Fig 3)
Once you press the same function button or touch the “Hold” on the touch screen would hold
measurement and the display.

How to Change the Range
When the Auto Range function is OFF (as described in Chapter 4), the range key will be activated
during measurement. (Fig 3) Touching “Range” on the touch screen or pressing the function button
R 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.
