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)

Frequency Weighting Network Characteristics 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.
