Naudojimo instrukcijos

1. Ekrano supratimas

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:

• Data ir laikas: Dabartinė data ir laikas.
• Baterijos indikatorius: Rodo likusį akumuliatoriaus veikimo laiką.
• Matavimo diapazonas: Indicates the active decibel range (e.g., 30-130 dB).
• Fast / Slow Time Weighting: Displays the selected time weighting mode.
• Oro kondicionieriaus svertinis koeficientas: Shows whether A-weighting or C-weighting is active.
• USB jungties indikacija: Appears when connected to a PC.
• Duomenų sulaikymas: 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-Weighting (A): Imituoja žmogaus ausies reakciją į garsą, dažniausiai naudojamas aplinkos triukšmo matavimams.
• C-Weighting (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 A/C mygtuką.

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 mygtuką.

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.
