Specifications Lutron SL-4001 Sound Level Meter

Display 18mm (0.7″) LCD (Liquid Crystal Display), 3 1/2 digits
Functions dB (A & C frequency weighted), time weighted (Fast, Slow), Max. hold down, AC & DC output
Measurement Range 3 ranges, 30 to 130 dB, input signal only
Resolution 0.1 dB
Accuracy The frequency weighting complies with IEC 651 type 2, calibrating the input signal at 94 dB(31.5 Hz to 8 kHz), then the accuracy of the A weighting is determined as follows:
31.5 Hz – ± 3 dB, 63 Hz – ± 2 dB, 125 Hz – ± 1.5 dB
250 Hz – ±1.5 dB, 500 Hz – ±1.5 dB, 1 kHz – ±1.5 dB
2 kHz – ± 2 dB, 4 kHz – ± 3 dB, 8 kHz – ± 5 dB
Frequency Weighted Networks 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-weighted – 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 Electric condenser microphone
Microphone size standard 1/2 inch size
Range selector 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,
* The “Fast” range is simulated with the response time of the human ear with a weight. The “Slow” range is easy to get an average value of the sound vibration level.
Calibration * Build in external calibration VR, easy to calibrate with external screw driver.
* Internal oscillation system, 1 KHz sine wave generator
Output Signal * AC Output – AC 0.5 Vrms corresponding to each step of the range.
* DC output – 0.3 to 1.3 VDC DC, 10 mV per dB.
* Output impedance – 600 ohms.
Output terminals 3.5 telephone output terminals are provided for connection with analyzers, level recorders, tape recorders
Operating Temperature 0℃ to 50℃(32℉ to 122℉)
Operating Humidity Less than 80% RH
Power Supply 006P DC 9V battery (heavy duty type)
Power Consumption Approx. DC 6mA
Dimensions 205 x 80 x 35 mm (8.1 x 3.2 x 1.4 inches)
Weight 280 g/0.62 lb (including battery)
