The 1.62-inch HD backlit display shows the current sound pressure level (SPL) in decibels (dB), along with indicators for selected frequency weighting (A or C), response time (FAST or SLOW), and MAX/MIN hold status. A dynamic scale also provides a visual representation of the sound level.

4. Setup

4.1 Instalasi baterei

The SW-524 requires three 1.5V AAA batteries (not included). To install:

1. Goleki tutup kompartemen baterei ing mburi piranti.
2. Geser utawa copot tutup tutup kanggo mbukak.
3. Lebokake telung baterei AAA, priksa manawa polaritas (+/-) sing bener kaya sing dituduhake ing njero kompartemen.
4. Ganti tutup kompartemen baterei kanthi aman.

4.2 Powering On / Off

Tekan ing Tombol Ngalih Daya (red button with power symbol) to turn the device on. Press and hold the same button for a few seconds to turn the device off.

5. Instruksi Operasi

5.1 Pangukuran dhasar

Once powered on, the device will immediately begin measuring sound levels. The current sound pressure level will be displayed on the screen in decibels (dB).

5.2 MAX/MIN Hold Function

Tekan ing MAX/MIN tombol kanggo muter liwat:

• MAX: Displays the maximum sound level recorded since the function was activated.
• MIN: Displays the minimum sound level recorded since the function was activated.
• Normal: Returns to real-time measurement.

5.3 A/C Frequency Weighting

Tekan ing A/C button to select the desired frequency weighting:

• A-bobot: Simulates the human ear's response to sound, commonly used for environmental noise measurements.
• C-bobot: Provides a flatter response, suitable for measuring peak sound levels or noise from machinery.

5.4 FAST/SLOW Response Time

Tekan ing CEPAT / Alon button to select the response time:

• CEPAT: (125ms) Captures rapid changes in sound level.
• Alon: (1 second) Provides an averaged reading, suitable for stable noise sources.

5.5 Kontrol Lampu Latar

Tekan ing Lampu Bohlam button to turn the display backlight on or off, improving visibility in low-light conditions.

5.6 Data Logging and PC Communication (SW-524 Only)

The SW-524 model includes advanced features for data logging and computer communication:

• Fungsi Memori: The device can continuously store data at 1-second intervals for up to 17 hours.
• Tampilan Wektu: The SW-524 can display the current time.
• Komunikasi PC: Connect the device to a computer via the MicroUSB port to download stored data, perform real-time sampling, and print reports using compatible software.
