Product Specifications

Display1 8 mm (0.7") LCD (Liquid Crystal Display), 3 1/2 digits.
Measurement Range3 ranges ( 30 - 70 dB, 60 - 100 dB, 90 - 130 dB ),
Resolution0.1 dB.
AccuracyFrequency weighting meet IEC 61672 Class 1, calibrating input signal on 94 dB the accuracy of frequency
weighting is specified as following:
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 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.
Range selector30 to 70 dB, 60 to 100 dB, 90 to 130 dB, 40 dB on each step,
with over & under range indicating.
Frequency31.5 Hz to 16 KHz. * Accuracy is tested within 31.5 Hz to 8 KHz.
Microphone typeElectric condenser microphone.
