Käyttöohjeet

1. Näytön ymmärtäminen

Image: A detailed breakdown of the Benetech GT1355A Decibel Meter's LCD screen, highlighting elements such as Date & Time, Battery Indicator, Measurement Range, Fast/Slow Time Weighting, A/C Weighting, USB Connection Indication, Data Hold, Min & Max Values, and controls for Settings, A/C, F/S (Fast/Slow), and REC (Record).

The LCD screen provides real-time information about sound levels and device status:

• Päivämäärä ja aika: Nykyinen päivämäärä ja kellonaika.
• Pariston ilmaisin: Näyttää jäljellä olevan akunkeston.
• Mittausalue: Indicates the active decibel range (e.g., 30-130 dB).
• Fast / Slow Time Weighting: Displays the selected time weighting mode.
• Ilmastointikustannusten painotus: Shows whether A-weighting or C-weighting is active.
• USB Connection Indication: Appears when connected to a PC.
• Tietojen pito: Indicates if the current reading is frozen.
• Min & Max Values: Displays the minimum and maximum sound levels recorded during the current session.
• Real-time Graph: A dynamic graph showing sound level changes over time.

2. Selecting Weighting and Time Response

The meter offers A and C weighting, and Fast/Slow time response settings to suit different measurement needs.

Image: An illustration explaining A-weighted and C-weighted sound measurement. A-weighting (30-130dB) assesses human ear perceived noise, while C-weighting (35-130dB) measures equipment noise, showing the decibel meter's capability to measure sound closer to human ear perception.

• A-painotus (A): Simulates the human ear's response to sound, commonly used for environmental noise measurements.
• C-painotus (C): Provides a flatter response, suitable for measuring the true sound level of machinery or peak noise.
• To switch between A/C weighting, press the Ilmastointi -painiketta.

Image: An illustration demonstrating the Fast and Slow Time Weighted switching options on the decibel meter. Fast time weighting is for measuring fluctuating unsteady noise, while Slow time weighting is for measuring steady state noise.

• Fast (F): For measuring rapidly changing or impulsive noise.
• Slow (S): For measuring steady or slowly changing noise levels.
• To switch between Fast/Slow time weighting, press the F/S -painiketta.

3. Setting Visual Alarms

The GT1355A features a three-color visual alarm system to indicate noise levels relative to set thresholds.

Image: A visual representation of the decibel meter's three-color visual alarm system. It shows the device's indicator light and screen changing color based on noise levels: blue for "Not Exceeded Alarm Value," yellow for "Low Alarm Value Exceeded," and red for "Exceeding High Alarm Value."

Image: A close-up of the decibel meter's screen showing the menu for customizing alarm thresholds. It displays options to set "red alarm" and "yellow alarm" values, with a note that the high alarm value must be higher than the low alarm value for successful setting.

• Access the alarm settings through the menu.
• Set a "yellow alarm" threshold for a lower warning level.
• Set a "red alarm" threshold for a higher critical level.
• Ensure the red alarm value is higher than the yellow alarm value.
• The alarm setting range is 30 to 130dB.

Huolto

1. Puhdistus

• Pyyhi laite pehmeällä, kuivalla liinalla.
• Älä käytä hankaavia puhdistusaineita tai liuottimia.
• Ensure the microphone and screen are free of dust and debris.

2. Varastointi

• Säilytä laitetta viileässä, kuivassa paikassa, poissa suorasta auringonvalosta ja äärimmäisistä lämpötiloista.
• Jos säilytät akkua pitkään, varmista, että se on osittain ladattu (noin 50 %) sen käyttöiän pidentämiseksi.
• Keep the windproof sponge on the microphone to protect it.

3. Kalibrointi

The decibel meter is factory calibrated at 94 dB @ 1kHz. For professional applications requiring high precision, periodic re-calibration by a certified laboratory is recommended.
