Specifications Lutron MSL-388SD Sound Level Data Recorder

CircuitCustom one-chip LSI microprocessor circuit
Featuring* LCD Size: 50 mm x 30 mm
* LCD with backlight (ON/OFF)
Measurement TypeSPL : Sound pressure level
Measuring RangeSPL:30-80.50-100.80-130 , Auto 30 – 130 dB
Resolution0.1 dB
Function* dB (frequency weighting A & C)
* Time weighting (Fast, Slow)
* Data hold, PEAK HOLD
* Record (Max., Min.)
Accuracy* The characteristics of the “A” frequency weighted network comply with IEC 61672-1-2013 class 2.
* Under 94 dB input signal, the accuracy is:
– 31.5 Hz reading ± 3.0 dB
– 63 Hz reading ± 2.0 dB
– 125 Hz reading ± 1.5 dB
– 250 Hz reading ± 1.5 dB
– 500 Hz reading ± 1.5 dB
– 1 KHz reading ± 1.0 dB
– 2 KHz reading ± 2.0 dB
– 4 KHz reading ± 3.0 dB
– 8 KHz reading ± 5.0 dB
Frequency Weighting Network* Characteristics A & C.
* Weighting : Characteristics simulated in response to “Listen to Human Ears”. Usually, when measuring environmental noise levels, always select the A weighting.
* Weighting C: Characteristics close to the response “FLAT”. Typical, suitable for checking engine noise (Q.C.check) & knowing the sound pressure level of the equipment being tested.
Data storageTo freeze measurement values
PEAK HoldTo Maintain the peak measurement value (max.)
Time weighting (FAST & SLOW)* Fast – t = 125 ms The “Fast” range is simulated by weighting human ear response times.
* Slow – t = 1 s The “Slow” range is easy to get the average value of the sound vibration level.
SPL selector function* Range: 30-80dB, 50-100dB, 80-130dB
* Auto range:30~130dB
Frequency31.5 to 8000 Hz
Microphone typeElectric condenser microphone
Microphone sizeOuter size, DIA 12.7 mm. (1/2 inch)
