To turn on the sound level meter without using the automatic shutdown function, press the Data hold/Backlight button and the Power button
simultaneously. To restore the automatic shutdown function, turn the meter off and on again.
MAX/MIN measurement
Pressing the MAX/MIN button once sets the device into the MAX mode [3]. In the MAX mode, the device shows the maximum data value
during the current measurement cycle.
Pressing the MAX/MIN button twice sets the device into the MIN mode [4]. In the MIN mode, the device shows the minimum data value
during the current measurement cycle.
To exit the MAX/MIN measurement modes, press the MAX/MIN button and hold it for 2 seconds.
FAST/SLOW time weighting
Press the F/S button to choose between fast (125ms) and slow (1s) time weighting modes. The display shows either FAST [14] or SLOW [8]
icon, depending on which mode is currently selected.
Select fast time weighting mode to capture noise peaks and quick-emerging noises. This mode is suitable for most applications.
Select slow time weighting mode to monitor sound sources with consistent noise levels and average out the quickly changing noises.
Data hold mode
Press the Data hold/Backlight button to hold the current measurement values on the display. The Data hold icon [2] will light up on the
display. In the Data hold mode, the device will show the last recorded sound, temperature, and humidity measurement values on the display.
To exit the Data hold mode, press the Data hold/Backlight button again.
Display backlight
Press the Data hold/Backlight button for two seconds to turn the display backlight on or off.
Relative humidity measurement
The sound level meter is equipped with a relative humidity sensor. The relative humidity measurement value (percentage) is shown in the
field [7] on the display.
Temperature units
The sound level meter is equipped with a temperature sensor. The temperature measurement value is shown in the field [16] on the display.
Use the °C/°F button to switch the temperature measurement unit between degrees Celsius (°C icon [15]) and degrees Fahrenheit
(°F icon [17]).
A- and C-weighted values
The sound level meter can measure both A- and C-weighted sound values. To switch between the weighting modes, press the °C/°F button
for two seconds. Icons A [9] and C [10] on the display represent the currently chosen mode.
In the A-weighting mode, the meter captures the sound level in approximately the same way as the human ear does, cutting off the lower
and higher frequencies. This mode is suitable for assessing the noise level of work environments and other public spaces to comply with the
occupational health and safety requirements.
In the C-weighting mode, the meter captures the sound level with a much flatter frequency response. This mode is used to analyze the
loudness of motors, machines, and other working equipment.
Low battery indication
When the battery voltage is low, the device shows the low battery icon [5]. It is recommended to replace the exhausted battery as soon as
possible to avoid inaccurate readings.
To avoid damaging the device, do not open the battery compartment cover when the device is turned on.
