Lutron SL-4001 Sound Level Meter
Measurement Range 3 ranges, 30 to 130 dB, input signal only.
Resolution 0.1 dB.
Accuracy Frequency weighting meet IEC 61672 class 2, calibrating input signal on 94 dB(31.5 Hz to 8
(23 ± 5 ℃) kHz), then the accuracy of frequency weighting is specified as following:
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
Characteristics of A & C.
Frequency A weighting - The characteristic is simulated as "Human Ear Listing" response. Typical, if making
Weighting Network the environmental sound level measurement, always select to A weighting.
C weighting - The characteristic is near the "FLAT" response. Typical, it is suitable for checking the
noise of machinery (Q.C. check) & knowing the sound pressure level of the tested
equipment.
Frequency 31.5 Hz to 8,000 Hz.
Range selector 30 to 80 dB, 50 to 100 dB, 80 to 130 dB, 50 dB on each step,
with over & under range indicating.
Time weighting Fast - t= 200 ms, Slow - t = 500 ms,
(Fast & Slow) * "Fast" range is simulated the human ear response time weighting.
"Slow" range is easy to get the average values of vibration sound level.
DC 9V battery(heavy duty type).
Power Consumption Approx. DC 6mA.
