Functions and technical features of the

device

Description

Spl-Lab Mini Bass Meter is a new device for measuring sound pressure and voltage. This device

is, probably, the most compact SPL meter of those available on the market today. The

uniqueness of this device is in its capability of simultaneously measuring sound pressure and

voltage. At the same time, it is possible to capture sound pressure at the moment of reaching the

highest SPL value. The measured signal can be provided by both industrial equipment and

acoustic systems. The device is simple in use and does not require additional settings and

calibration. It is enough to simply connect the device to a car cigarette lighter for measuring

sound pressure and voltage. The device can be attached to the windshield of a car and the

measurements taken while driving. The Mini Bass Meter is completely autonomous, which

eliminates inaccurate readings.

Ergonomics

Spl-Lab Mini Bass Meter has a compact case, including a four segment display, 3 control

buttons, Mini-USB slot for power supply and updating the firmware and an input for connecting

to a cigarette lighter socket. The design of the device allows it to practically fit into any car

interior.

Working with the device

Important safety information:

！The manufacturer does not bear responsibility for damage, caused directly or indirectly, as a

result of improper device use.

！Before using the device, examine its case for cracks and splits. Any depressurization of the

device will result in possible damage.

！To avoid the risk of electric shock, all connector cables should not have insulation defects.

！Avoid measuring load beyond its maximum limit.

！All operations of connecting and disconnecting cables should be performed with equipment

off.

！Do not use or store the device in areas with high humidity or heat, as well as, close to devices

generating a strong magnetic field.

！During the preventive maintenance of the device, do not use synthetic detergents or solvents.

Using wet wipes is more preferable.

Values on screen will blink if the Hold Mode is enabled.

Service mode

For entering Service Mode, press buttons #1 & #3 when switching the device on and wait until

the blinking text, “CFG”, appears on screen.

Select necessary parameter by pressing Functional button #3.

Set the necessary parameter value using Functional buttons #1 (decreasing value) and #3

(increasing value).

After setting the last parameter and pressing Functional button #2, the device will save

the selected parameters and will change to measuring mode.
