5. Operating Instructions

5.1 Power On/Off

• To power on the device, press the ON-OFF button. The LCD display will illuminate.
• To power off the device, press and hold the ON-OFF button until the display turns off.

5.2 Taking Measurements

Once powered on, the meter will immediately begin displaying the current sound level in decibels (dB).

• Hold the meter with the microphone pointed towards the sound source.
• Ensure no obstructions are blocking the microphone.
• The measurement range is 30dB to 130dB. Readings outside this range may not be accurate.

5.3 Fast/Slow Mode Selection

The FY8862 offers two response modes for different measurement needs:

• Press the FAST/SLOW button to toggle between modes.
• FAST Mode: Displays sound levels in real-time (125ms response time). Suitable for capturing sudden noise peaks or rapidly changing sound levels.
• SLOW Mode: Displays the current average sound level over a longer period (1000ms response time). Ideal for measuring stable noise levels or when noise fluctuations are less frequent.
