Using the device in different way, then described in the user’s manual or its non-intended use can pose a danger
or result in hardware damage. Before starting a measurement, it is strongly suggested to read carefully the user’s
manual.
Usage in environmental conditions that are not inconsistent with the specification can lower the safety level or
decrease device functional parameters. It is advised to pay attention to possibility of water condensation in case
of moving the device from a cold work environment to a warmer one.
One of the device applications is a vibration measurement of machines or devices. In case of technical state
investigation of devices which are powered by voltage higher that 60 VDC, 30 VACrms or having moving parts, it is
recommended to take special care.
If the device has been damaged, operates in a way inconsistent with the user’s manual or it’s been in
environmental conditions other than specified for a long period of time it is advised to stop using it immediately.
Next use can be possible after performing service work of the device by the manufacturer.
The device should be cleaned by a soft cloth. Use soft detergents (e.g. dishwashing liquids) if necessary.
It is advised not to use the device if any of its components has been damaged. It concerns especially the power
supply.

2. PRESERVATION OF ENVIRONMENT
The device is subject to a directive WEEE 2012/19/UE regarding waste electronic and electric devices.
A symbol of crossed waste bin means that the product has to be utilized separately and should be delivered
to the right waste collection point. It should not be thrown out along with a household waste.
If you would like to know more about it, contact a company representative or local authorities in charge of
waste management.

5. WIRELESS VIBRATION SENSOR MVIBE
mVIBE is a multi-parameter wireless sensor for technical state evaluation of industrial equipment, including moving components
of machines, its construction elements and construction objects. It is beyond a competition in the field of high performance,
exceptional functionality, as well as the price.
Piezoelectric accelerometers are a main source of signal, which measure vibrations in two directions. Their outstanding
parameters combined with 24-bit signal conversion allow to achieve accurate measurement results without necessity to change
measurement ranges. Wide frequency band (0,5 Hz to 20 kHz) satisfies requirements of the most applications connected with
technical condition assessment or damage diagnostics of machines and building constructions. Three-dimensional
measurements within 0Hz to 1,5 kHz frequency range can be made with a built-in MEMS sensor. In combination with 3D highly
sensitive silicon gyroscope it allows for determination of mVIBE movement in 6D space.
Measurement capabilities are complemented by an ultrasound microphone, which registers sound in range up to 51 kHz.
It’s a tremendous tool to detect shocks, which occur in damaged bearings and gearboxes. Together with the dedicated software
they allow to detect leakiness in compressed-air systems.
The measurement information from mVIBE sensor through WiFi interface is transmitted to a smartphone or a tablet.
In permanent monitoring systems it can be sent directly to local or external diagnostic cloud. The mobile device with dedicated
software installed acts as the user interface. Huge computing power and high-resolution screens combined with intuitive expert-
driven software make signal analysis easy and effective.
In the basic system version mVIBE operates with mVIBE Soft tool available in GooglePlay. It creates fundamental tool for machines
technical state evaluation and fault diagnosis. The advanced options covering signal storage in database, localization structure
with NFC identification, fully configurable detailed signal analysis functions are offered by mVIDIA software. It can be integrated
with cloud or server-based machine diagnostic environment VIDIA. Detailed information is available on manufacturer website
www.alitec.pl or www.vibrations.pl.

mVIBE is powered by internal Li-Ion rechargeable battery. Its high capacity ensures operating time up to 8 hours (continuous
measurement with data transmission). The sensor can be attached to the investigated object by magnetic holder or M6 screw
thread. As an option magnetic holder for curved surfaces is delivered.
The highest accuracy of the mVIBE sensor can be confirmed by piezoelectric sensor calibration certificate issued by Polish Central
Office of Measurement.
