Key specifications

 Frequency response: 31.5 Hz–8 kHz
 Measurement modes: continuous level and peak detection
 Weight and form factor: handheld, lightweight for portable use
 Output and display: real-time numeric display of sound levels
How to use
Power on the unit and select the desired measurement mode. Hold the meter at arm’s length with the microphone pointed toward the sound source, avoiding obstructions and reflective surfaces close to the microphone. Allow the instrument to stabilize to capture continuous readings, and switch to peak detection to record transient events. Record readings directly from the display or note peak values as required for reports and diagnostics.
Usage recommendations
Place the meter at a consistent distance from the source and avoid placing the microphone within a few centimeters of surfaces that can reflect sound. For workplace or environmental assessments, perform measurements at representative locations and at times that reflect typical operating conditions. Calibrate or verify the meter periodically according to relevant procedures to maintain measurement accuracy.
