Figure 3: High-definition backlit display showing a sound level reading.
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. Seadistamine
4.1 Aku paigaldamine
The SW-524 requires three 1.5V AAA batteries (not included). To install:
- Leidke seadme tagaküljelt patareipesa kate.
- Avamiseks libistage kaant või tehke sellest lahti klõps.
- Sisestage kolm AAA-patareid, jälgides õiget polaarsust (+/-), nagu on näidatud sahtlis.
- Asetage patareipesa kate kindlalt tagasi.
4.2 Sisse-/väljalülitamine
Vajutage nuppu Toitelüliti võti (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. Kasutusjuhised
5.1 Põhimõõtmine
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
Vajutage nuppu MAX/MIN nuppu, et läbi vaadata:
- MAKS: Displays the maximum sound level recorded since the function was activated.
- MIN: Displays the minimum sound level recorded since the function was activated.
- Tavaline: Returns to real-time measurement.
5.3 A/C Frequency Weighting
Vajutage nuppu A/C button to select the desired frequency weighting:
- A-kaalumine: Simuleerib inimese kõrva reaktsiooni helile, mida tavaliselt kasutatakse keskkonnamüra mõõtmiseks.
- C-kaalumine: Provides a flatter response, suitable for measuring peak sound levels or noise from machinery.
5.4 FAST/SLOW Response Time
Vajutage nuppu KIIRE AEGLANE button to select the response time:
- KIIRE: (125ms) Captures rapid changes in sound level.
- AEGlane: (1 second) Provides an averaged reading, suitable for stable noise sources.
5.5 taustvalgustuse juhtimine
Vajutage nuppu Lambipirn 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:
- Mälu funktsioon: The device can continuously store data at 1-second intervals for up to 17 hours.
- Aja kuvamine: The SW-524 can display the current time.
- PC Communication: Connect the device to a computer via the MicroUSB port to download stored data, perform real-time sampling, and print reports using compatible software.

5.7 Alarm Function (SW-524 Only)
The SW-524 allows you to set a high limit alarm. If the measured sound level exceeds this preset limit, the device will provide an alert. Refer to the device's on-screen menu or accompanying software for specific instructions on setting the alarm threshold.
5.8 AC/DC Signal Output
The device features dual analog signal outputs (AC and DC) to connect to external recording devices, data loggers, or analyzers.
- DC väljund: 10mV/dB, output impedance approx. 100Ωhm.
- AC väljund: 0.65Vrms/full scale per gear, output impedance approx. 600Ωhm.

6. Hooldus
6.1 Puhastamine
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the microphone and sponge ball are kept clean and free from dust or debris.
6.2 Säilitamine
Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, remove the batteries to prevent leakage and potential damage to the device.
