Instruccions de funcionament
1. Comprensió de la pantalla
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 i hora: Data i hora actuals.
- Indicador de bateria: Mostra la durada restant de la bateria.
- Interval de mesura: Indicates the active decibel range (e.g., 30-130 dB).
- Fast / Slow Time Weighting: Displays the selected time weighting mode.
- Ponderació del aire condicionat: Shows whether A-weighting or C-weighting is active.
- Indicació de connexió USB: Appears when connected to a PC.
- Conservació de dades: 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): Simulates the human ear's response to sound, commonly used for environmental noise measurements.
- 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 botó.
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 botó.
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.
