SL-4013 - Digital Sound Level Meter with Separate Microphone Features: - Separate sound probe, easy operation.- Large LCD display, easy to read.- Frequency weighting meets IEC 61672 type 2.- Auto range & manual range.- A & C frequency weighting.- Fast & Slow time weighting. Specifications: Display52 mm x 32 mm LCD (Liquid Crystal Display), 5 digits FunctiondB (A & C frequency weighting), Time weighting(Fast, Slow), Hold, Memory (max. & min.), Peak hold, AC & RS232 output. Measurement Range 30 - 130 dB Resolution 0.1 dB. Accuracy (23 +-5 C) Frequency weighting meet IEC 61672 class 2, calibrating input signal on 94 dB ( 31.5 Hz to 8 KHz), then the accuracy of frequency weighting is specified as following: 31.5 Hz: +- 3 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 dB2 kHz: +- 2.6 dB, 4 kHz: +- 3.6 dB, 8 kHz: +- 5.6 dBFrequency Weighting Network A weighting: The characteristic is simulated as "Human Ear Listing" response. Typical, if making 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. Calibrator B & K (Bruel & kjaer), multifunction acoustic calibrator, model : 4226. Microphone Electric condenser microphone. Size of microphone 1/2 inch standard size Range selector Auto range : 30 to 130 dB. Manual range : 3 range, 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 & Slow) Fast - t= 200 ms, Slow - t = 500 ms, a)"Fast" range is simulated the human ear response time weighting.b)"Slow" range is easy to get the average values of vibration sound level.c) The "Fast" & "Slow" time weighting range are designed to IEC 61672 class 2 requirement Output Signal a) AC output - AC 0.5 Vrms corresponding to each range step. Output impedance - 600 ohm. b) RS232 output.
