General Information
The Wireless Bass Meter noise meter (Second Edition) is intended for measuring the noise level
and sound pressure at the low frequency. The measured signal can be provided by both the
industrial equipment and the acoustic systems. The distinctive feature of the noise meter is its
ease of use and mobility. No more wires! It allows taking measurements in complex
environment, where use of wired devices is problematic. Owing to the built-in ADC measured
signal is digitalized inside the device and sent to your PC or smartphone/tablet PC via wireless
network (WiFi) without alterations. Usage of the solid-state pressure transducer allows receiving
results with high accuracy of 0.1 dB.
Ergonomics
The Wireless Bass Meter (Second Edition) device is performed as a monoblock, combining the
high-frequency solid-state sensor, ADC module and WiFi module. The device has Power button,
LED, USB port and a feature button. There is of charging completion indication and low battery
level indication. At the back cover there are vacuum suction cups for affixing the device on any
smooth surfaces, for example, glass. The case of the device is made of shockproof plastic
material.
Package Contents
Wireless Bass Meter (second edition) Noise Meter
Spl-Lab Measuring Center software for Windows
Audio-CD with audio tracks for tuning (sine, sweep-tones, noise)
USB cable for charging

Working with the device
Important safety information:
！The manufacturer does not bear responsibility for damage, caused directly or indirectly, as a
result of improper use of device.
！Before using the device, examine its case for cracks and splits, because any depressurization
of the device will result in its breakage.
！To avoid the risk of electric shock all the connector cables should not have insulation defects.
！Avoid measuring load beyond the maximum limit.
！Do not use or store the device in the areas with high humidity or heat, as well as, close to the
devices, generating strong magnetic field.
！During the preventive maintenance of the device do not use the synthetic detergents, do not
apply solvents. Using wet wipes is more preferable.
！Before starting the device and a system on the whole, ensure that all the connection cables
are plugged in correctly.
