Specifications

Specifications
Display18mm (0.7") LCD (Liquid Crystal Display), 3 1/2 digits.
Measurement Range3 ranges, 30 to 130 dB, input signal only.
Resolution0.1 dB.
FunctiondB (A & C frequency weighting), Time weighting(Fast, Slow), Max. hold, AC & DC output.
AccuracyFrequency weighting meet IEC 61672-1-2013 class 2, calibrating input signal on 94 dB(31.5 Hz to 8; (23 ± 5 °C) kHz), then the accuracy of frequency weighting is specified as following: 31.5 Hz -reading ± 3.0 dB, 63 Hz -reading ± 2.0 dB, 125 Hz -reading ± 1.5 dB; 250 Hz -reading ± 1.5 dB, 500 Hz -reading ± 1.5 dB, 1 kHz -reading ± 1.0 dB; 2 kHz -reading ± 2.0 dB, 4 kHz -reading ± 3.0 dB, 8 kHz -reading ± 5.0 dB
Frequency Weighting NetworkCharacteristics of A & C.; A weighting - The characteristic is simulated as "Human Ear Listening" 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.
Time weightingFast - t= 125 ms, Slow - t = 1 sec.; * "Fast" range is simulated the human ear response time weighting.; "Slow" range is easy to get the average values of vibration sound level.
Range selector30 to 80 dB, 50 to 100 dB, 80 to 130 dB, 50 dB on each step; with over & under range indicating.
