GENERAL SPECIFICATIONS

Display 52 mm x 32 mm LCD (Liquid Crystal Display), 5 digits.
Function dB (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 ℃) Frequency weighting meet IEC 61672 type 2, calibrating input signal on 94 dB(31.5 Hz to 8 kHz), then the accuracy of A weighting is specified as following:
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, 2kHz - ± 2 dB, 4 kHz - ± 3 dB, 8 kHz - ± 5 dB.
Frequency Weighting NetworkCharacteristics of A & C.
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.
Frequency 31.5 Hz to 8,000 Hz.
Calibrator B & K (Bruel & kjaer), multi-fuction 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,
  • "Fast" range is simulated the human ear response time weighting.
    "Slow" range is easy to get the average values of vibration sound level.
  • The "Fast" & "Slow" time weighting range are designed to IEC 61672 type 2 requirement.
Output Signal
  • AC output - AC 0.5 Vrms corresponding to each range step.
    Output impedance - 600 ohm.
  • RS232 output.
Out terminal Terminal 1 : RS232 computer interface terminal.
Terminal 2 : AC output terminal.
  • Terminal socket size : 3.5 mm dia. phone socket.
