Display1 8 mm (0.7″) LCD (Liquid Crystal Display), 3 1/2 digits
FunctionsdB (A & C frequency weighted), time weighted (Fast, Slow), Max. hold on, Max. hold reset, AC output
Measurement Range3 ranges (30 – 70 dB, 60 – 100 dB, 90 – 130 dB )
Resolution0.1 dB
AccuracyThe frequency weighting meets IEC 61672 Class 1, calibrating the input signal at 94 dB the frequency weighting accuracy is specified as follows:
31.5 Hz : ± 2.0 dB, 63 Hz : ± 1.5 dB, 125 Hz : ± 1.5 dB,
250 Hz : ± 1.4 dB, 500 Hz : ± 1.4 dB, 1 KHz : ± 1.1 dB,
2 KHz : ±1.6 dB, 4 KHz : ±1.6 dB, 8 KHz : +2.1 dB to -3.1 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-weighted – Characteristics approximate a “FLAT” response. Typical, suitable for checking engine noise (Q.C. check) & knowing the sound pressure level of the equipment under test.
Frequency31.5 Hz to 16 KHz. * Accuracy tested in the range of 31.5 Hz to 8 KHz
CalibratorB & K (Bruel & kjaer), multifunction acoustic calibrator, model: 4226
Microphone typeElectric condenser microphone
Microphone Sizestandard 1/2 inch size
Range Selector30 to 70 dB, 60 to 100 dB, 90 to 130 dB, 40 dB at each step, with over & under range indication
Fast & Slow Time Weighting (F & S )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 levelThe “Fast” & “Slow” time weighting ranges are designed for IEC 61672 Class 1 requirements
Output SignalAC output – AC 750 mVrms per step of range
