6. Istruzzjonijiet Operattivi
6.1 Power On/Off
Agħfas il- ⑂ button to turn the meter on. Press and hold the ⑂ agħfas il-buttuna għal ftit sekondi biex titfiha.
6.2 Kejl Bażiku
Once powered on, the meter will immediately begin displaying real-time sound pressure levels in dBA. Position the microphone towards the sound source for accurate readings.
6.3 Funzjoni MAX/MIN
Agħfas il- MIN / MAX buttuna biex tiċċirkola bejn il-modi ta' wiri li ġejjin:
- Qari kurrenti: Real-time sound level.
- MAX: Displays the maximum sound level recorded since the meter was powered on or the MAX/MIN function was reset.
- MIN: Displays the minimum sound level recorded since the meter was powered on or the MAX/MIN function was reset.
To reset the MAX/MIN values, turn the meter off and then on again.
6.4 Funzjoni HOLD
Agħfas il- ŻOMM button to freeze the current reading on the display. The 'HOLD' indicator will appear on the LCD. Press the ŻOMM button again to release the reading and return to real-time measurement.
6.5 Dawl ta 'wara
The backlight typically activates automatically in low light or can be toggled by a short press of the power button (if available on your model, refer to specific device markings).
6.6 Datalogging via App
With the meter connected to the 'dB Tester' app:
- Navigate to the recording section within the app.
- Set desired recording intervals and duration.
- Initiate data logging. The meter can store up to 20,000 data points internally, which can then be uploaded to the app for review, analysis, and export.
7. Nifhmu l-Qari
Sound pressure levels are typically measured in decibels (dB). The Landtek MILA37900 measures in dBA, which is a weighted scale that approximates the human ear's response to sound. Refer to the chart below for common noise ranges and their implications.
Figure 9: Noise level chart.
| dB Range | Deskrizzjoni |
|---|---|
| 15dB | Skiet |
| 15 sa 20dB | Kwiet |
| 20 sa 40dB | Whispering |
| 40 sa 60dB | Konversazzjoni normali |
| 60 sa 70dB | Noise (e.g., busy office) |
| 70 sa 80dB | Very Noisy (e.g., vacuum cleaner) |
| Aktar minn 100dB | Damage to Hearing (prolonged exposure) |
