Overview
LANDTEK SL-5868P multifunctional sound level meter is an instrument for environment, machinery, traffic, ship and Miscellaneous noise sound level measurement. It is suitable for industrial environmental protection, construction, teaching and research departments.
Features
1. Three weighted "A"/"C"/"F" options and time weighted "fast" and "slow" options.
2. Four measurement parameters: Lp ordinary sound level measurement, Leq equivalent continuous A sound level measurement, Lmax maximum sound level measurement, LN statistical sound level measurement.
3. With DC output of 10 mV/dB.
4. Can store 30 sets of measurement data and measurement status.
5. Equipped with functions such as "alarm value setting", "output", "automatic shutdown and manual shutdown".
6. Use "USB data cable output" and "RS-232 data cable output" to communicate with PC.
7. Also provide "Bluetooth Bluetooth ™ data output" selection.
Principle
The sound level meter converts the sound signal into an electrical signal through the built-in microphone (microphone). After being amplified by an amplifier, the sound level value is finally displayed by the display through the A, C or F frequency weighting network and fast and slow time weighting processing. It can measure various parameters such as instantaneous sound level, equivalent continuous sound level, maximum sound level and statistical sound level, and can transmit the measurement results to the computer for further analysis through the data interface.
Applications
Environment monitoring, mechanical noise measurement, traffic noise measurement, ship noise measurement, industrial environmental protection, construction, teaching and research
Steps
1. Install the battery and turn it on.
2. Select the frequency weighting (A, C, or F) and time weighting (fast or slow) as required.
3. Select the measurement mode (e.g. Lp, Leq, Lmax or LN).
4. Set parameters such as alarm values (if necessary).
5. Start the measurement, the instrument will display and record the sound level data.
6. After the measurement is completed, the stored data can be transferred to the computer via USB, RS-232 or Bluetooth.
Notice
Do not use in environments with extreme temperatures, humidity or strong electromagnetic fields.
• Avoid exposure to moisture, heat, or physical impact on the microphone.
Periodically calibrated to ensure measurement accuracy.
• Pay attention to the battery level, and remove the battery when not in use for a long time.
When transferring data, ensure that the connection is stable.
