| 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 evel of the tested equipment. | |
| Time weighting (FAST & SLOW) | * Fast – t = 125 ms @”Fast” range is simulated the human ear response time weighting. * Slow – t = 1 s @”Slow” range is easy to get the average values of vibration sound level. | |
| Data hold | To freeze the measurement value | |
| Function selector SPL, DOSE | * Auto range：30～130dB * Threshold Level (Thr)：70～90dB in 1dB steps * Criterion Level(Crit)：80、84、85、90dB * Exchange Rate：3, 4, 5 or 6 dB | |
| Frequency | 31.5 to 8,000 Hz | |
