Specifications Lutron SL-4012 Sound Level Meter

  • Display: 52 mm x 32 mm LCD (Liquid Crystal Display), 5 digits.
  • Functions: dB (A & C frequency weighted), Time weighted (Fast, Slow), Hold,
  • Memory (max. & min.), peak hold, AC & RS232 output.
  • Measurement Range: 30 – 130 dB.
  • Resolution: 0.1 dB.
  • Accuracy: The frequency weighting complies with IEC 61672 class 2, calibrating the input signal at 94 dB(31.5 Hz to 8 kHz), then the frequency weighting accuracy is determined as follows:

31.5 Hz – ± 3.5 dB, 63 Hz – ± 2.5 dB, 125 Hz – ± 2.0 dB
250 Hz – ±1.9 dB, 500 Hz – ±1.9 dB, 1 kHz – ±1.4 dB
2 kHz – ± 2.6 dB, 4 kHz – ± 3.6 dB, 8 kHz – ± 5.6 dB

  • Frequency Weighting Network:

* Characteristics A & C.

Weighting – Characteristics are simulated in response to “Human Ear Listing”. Usually, when measuring environmental noise levels, always select the A weighting.
C weighting – Characteristics close to a “FLAT” response. Typical, suitable for checking engine noise (Q.C. check) & knowing the sound pressure level of the equipment under test.

  • Frequency: 31.5 Hz to 8,000 Hz.
  • Calibrator: B & K (Bruel & kjaer), multifunction acoustic calibrator, model: 4226.
  • Microphone type: Electric condenser microphone.
  • Microphone size: standard 1/2 inch size.
  • Range selector:

* Auto range: 30 to 130 dB.
* Manual range: 3 ranges, 30 to 80 dB, 50 to 100 dB, 80 to 130 dB, 50 dB at each step, with over & under range indication.

  • Time Weighting (Fast & Slow): Fast – t= 200 ms, Slow – t = 500 ms,

* “Fast” range simulated human ear response time weight.
The “slow” range is easy to get an average value of sound vibration level.
* The “Fast” & “Slow” time weighting ranges are designed for IEC 61672 class 2 requirements.

Output Signal:

* AC Output – AC 0.5 Vrms corresponding to each step of the range.
Output impedance – 600 ohms.
* RS232 output.

  • Output terminals:

Terminal 1 : RS232 computer interface terminal.
Terminal 2 : AC output terminal.
* Terminal socket size: 3.5mm diameter. telephone socket.

  • Operating Temperature: 0℃ to 50℃(32℉ to 122℉).
  • Operating Humidity: Less than 80% RH.
  • Power Supply: 006P DC 9V Battery (Alkaline type or heavy duty).
  • Power Consumption: Approx. DC 6mA.
  • Dimensions: 268 x 68 x 29 mm ( 10.6 x 2.7 x 1.1 inches).
