Accuracy
(23 ± 5°C) Frequency weighting meet IEC 651 type 2, calibrating input signal on 94 dB(31.5Hz to 8kHz), then the accuracy of A weighting is specified as following:.
31.5Hz ~ ± 3dB, 63Hz ~ ± 2dB, 125Hz ~ ± 1.5dB, 250Hz ~ ± 1.5dB,
500Hz ~ ± 1.5dB, 1kHz ~ ± 1.5dB, 2kHz ~ ± 2dB, 4kHz ~ ± 3dB,
8kHz ~ ± 5dB
Time Weighting
(Fast & Slow) Fast - t=200ms, Slow - t=500ms
*Fast range is simulated the human ear response time weighting.
*Slow range allows you to get the average values of sound vibration
 level.
*The "Fast" & "Slow" time weighting range are designed to IEC 651
 Type2 requirement.
