2.1 બેટરી ઇન્સ્ટોલેશન

1. ઉપકરણની પાછળ બેટરી કમ્પાર્ટમેન્ટ કવર શોધો.
2. કમ્પાર્ટમેન્ટ ખોલવા માટે કવર સ્લાઇડ કરો અથવા અનક્લિપ કરો.
3. Insert two (2) AAA 1.5V batteries, ensuring correct polarity (+/-).
4. બેટરી કમ્પાર્ટમેન્ટ કવર સુરક્ષિત રીતે બદલો.

Note: Batteries are included with the device. Please ensure they are installed correctly before first use.

2.2 પ્રારંભિક પાવર-ઓન

After installing the batteries, press the power switch (labeled '3' in Figure 1) to turn on the device. The LCD display will illuminate, and the device will be ready for measurement.

3. ઓપરેટિંગ સૂચનાઓ

3.1 પાવર ચાલુ/બંધ

• ચાલુ કરવા માટે: દબાવો પાવર સ્વિચ.
• બંધ કરવા માટે: દબાવો પાવર સ્વિચ again. The device also features an automatic power-off function to conserve battery life.

3.2 માપ લેવું

Hold the sound level meter with the microphone (1) pointed towards the sound source. The current decibel level will be displayed on the LCD screen (6).

3.3 FAST/SLOW Time Weighting

દબાવો ઝડપી ધીમુ button (4) to select the desired time weighting:

• ઝડપી: Measures sound levels with a 125ms time constant, suitable for capturing sudden noise changes.
• સ્લો: Measures sound levels with a 1-second time constant, suitable for averaging fluctuating noise levels.

3.4 MAX/MIN Value Display

દબાવો MAX/MIN button (5) to cycle through the display modes:

• Current real-time measurement.
• Maximum (MAX) decibel value recorded since power-on.
• Minimum (MIN) decibel value recorded since power-on.

૫.૬ ઓટોમેટિક બેકલાઇટ

The device features an automatic LCD backlight sensor (2). The backlight will automatically illuminate in low-light conditions, making the display clearer and easier to read, especially at night or in dim environments.

Figure 3: The automatic backlight sensor ensures clear readability of the LCD display in various lighting conditions.

3.6 Windscreen Usage

When measuring in environments with wind speeds exceeding 10 meters per second, it is recommended to use a wind cover (MIC Enclosures Wind, 1) over the microphone. This helps to reduce wind noise interference and improve measurement accuracy.

3.7 Decibel Level Interpretation

• 1-15 ડીબી: શ્વાસ
• 15-20 ડીબી: Faint
• 20-40 ડીબી: Whisper
• 40-60 ડીબી: મધ્યમ
• 60-70 ડીબી: Affects sleep
• 70-90 ડીબી: Very noisy
• 100 ડીબી કરતાં વધુ: Damage hearing

4. જાળવણી

4.1 સફાઈ

To clean the device, use a soft, dry cloth. Do not use abrasive cleaners or solvents. Avoid immersing the meter in water or exposing it to excessive moisture.
