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.
31.5 Hz – ± 3 dB, 63 Hz – ± 2.5 dB, 125 Hz – ± 2.0 dB
250 Hz – ± 1.9 dB, 500 Hz – ± 1.9 dB, 1 kHz – ± 1.4 dB
2 kHz – ± 2.6 dB, 4 kHz – ± 3.6 dB, 8 kHz – ± 5.6 dB
Characteristics of A & C.
Frequency A weighting – The characteristic is simulated as “Human Ear Listing” response. Typical, if
Weighting Network 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.
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.
Fast – t= 200 ms, Slow – t = 500 ms,
Time Weighting * “Fast” range is simulated the human ear response time weighting.
(Fast & Slow) “Slow” range is easy to get the average values of vibration sound level.
* The “Fast” & “Slow” time weighting range are designed to IEC 61672 class 2 requirement.
Calibration VR Build in external calibration VR, easy to calibrate on 94 dB level by screw driver.Standard Accessories ( termasuk )
Instruction manual 1 PC.
Separate sound probe 1 PC.
Probe holder 1 PC.
