Overview
AMITTARI AS-126P Multifunctional Sound Level Meter is a portable device for environment, machinery, traffic, ship and Miscellaneous noise sound level measurement, suitable for industrial environmental protection, construction, health, teaching and research and other fields. It supports a variety of measurement parameters and weight selection, with data storage and communication functions.
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 10mV/dB; can store 30 sets of measurement data.
4. Equipped with alarm value setting, automatic shutdown and manual shutdown functions.
5. Use USB cable and Bluetooth data output to communicate with PC.
Principle
The sound level meter collects sound signals through a 12.5mm condenser microphone and makes measurements in the frequency range of 20 to 12,500Hz. The signals are weighted by A/C/F frequency and fast/slow time, and parameters such as Lp, Leq, Lmax, LN are calculated. The built-in calibrated signal ensures accuracy.
Applications
Environment, machinery, transportation, shipbuilding, industrial environmental protection, construction, health, teaching and research
Standards
IEC 651.2、ANSI 1.4.2
Steps
1. Install 4 AA batteries or connect an external 6V DC power supply.
2. Select frequency weighting (A/C/F) and time weighting (fast/slow).
3. Set measurement parameters (such as Lp, Leq, Lmax, LN) and alarm values (30~ 130dB).
4. Start measurement, data is automatically stored or output via USB/Bluetooth.
5. Use the built-in calibrating signal to calibrate regularly.
Notice
Make sure the battery is fully charged before use to avoid low voltage affecting the measurement.
• Regularly calibrate with ND9 acoustic calibrator to ensure accuracy.
• Operate within the measurement range to avoid over-limit use.
When storing data, pay attention to the capacity limit (30 sets).
• Optional accessories need to be connected correctly, such as a USB cable or Bluetooth adapter.
